VPRAŠANJE
Dear sirs
Were bidding your tender and we have few concerns related to the draft contract;
Can you clarify the few following topics please?

- Art. 13, art. 14 and art. 15, isnt exactly clear the kind and the limit of the tenderer liabilities:
We assume that they relate to direct damages only, not indirect ones; is it correct?
We assume that, in any case, the related indemnifications will never exceed the contract amount value; is it correct?

- Art. 22 and art. 23: is valid and applicable the following statement?
In the event of cancellation or termination of the contract, the Contracting Authority may require to the Contractor to transfer title and deliver any of the following items specifically produced or acquired under the contract: (i) completed or partially completed goods, (ii) work in process, and (iii) materials, parts, tools, dies, jigs, and fixtures.


ODGOVOR

Dear Sir/Madam,

1. The contractual penalty may be set at a maximum of 10% of the total contract value. While in the event of damage caused by Contractor, the Contracting Authority may claim compensation for any damage also above the amount of the contractual penalty (i.e. in the amount of the damage incurred). Also the contract does not specifically stipulate only direct damages, so both direct and indirect damages can be taken into account if they occur.

2. Articles 22 and 23 contain provisions that the contracting authority must include in every public procurement contract in accordance with the provisions of Slovenian public procurement legislation. Therefore, the statement as you state in this case is not applicable.

Kind regards.

VPRAŠANJE
We understood that the contractual penalty has a cap at 10% of the contract value;
We also understand that the damages eventually caused by the supplier have to be indemnified to the Contracting Authority and that can be higher than the 10% penalty;
The question is: what is the limit of the possible indemnification? It is limited to the value of the contract?
thanks

ODGOVOR

There is no value limit under the contract regarding possible liability. In accordance with the contract, the contracting Authority is obliged in such case to comply with applicable regulations or. principles regarding liability for damages, which is determined by the model contract in the third paragraph of Article 13.

It is essential for the contracting authority that the tenderer fulfills the contractual obligations by the deadline required by the contracting authority, as the contracting authority cannot extend the delivery period. If tenderer's obligations are fulfilled in accordance with the contract and by the deadline, there is no reason to impose any contractual penalty or any indemnification.

Kind regards.

VPRAŠANJE
Spoštovani,

po pregledu razpisne dokumentacije je bilo ugotovljeno, da navedene tehnične specifikacije Sklopa 1 »Sistem SEC« ustrezajo samo enemu ponudniku in s tem omejujejo konkurenco. Prosim za spremembo sledečih tehničnih specifikacij, ki same po sebi ne prispevajo k pridobitvi boljših rezultatov eksperimentov, ampak zgolj omejujejo možnost ponudbe drugih instrumentov.

1. Zahteva 3: »Diferencialni detektor refrakcijskega indeksa (valovna dolžina 640 nm)« - prosim, da se briše zahteva po valovni dolžini, kajti diferenčni način delovanja detektorja temelji na merjenju razlike lomnega količnika medija med referenčno in merilno celicama zato valovna dolžina optičnega vira ne vpliva na rezultat meritve, ter tudi ne prispeva k njegovemu izboljšanju. Predlagam, da se zahteva glasi »Diferencialni detektor refrakcijskega indeksa«.

2. Zahteva 4: »Spektrometer UV/Vis z diodno letvico (valovno območje: 190-900 nm)« - prosim, da se zahtevano valovno območje spremeni tako, da ustreza UV/Vis spektralnemu območju - t.j. 190-700 nm. Daljše valovanje namreč spada v NIR območju in ni del UV/Vis detektorjev. Predlagam, da se zahteva glasi »Spektrometer UV/Vis z diodno letvico (valovno območje: 190-700 nm)«.

3. Zahteva 5: »Detektor sipanja svetlobe z delovnimi koti 90 ° in 7 °, z visoko občutljivostjo (valovna dolžina 640 nm)« - prosim, da se iz zahteve umakneta zahtevi po valovni dolžini optičnega vira in po nižjem delovnem kotu 7 °, ker le-ti omejujeta ponudbo na samo enega proizvajalca opreme in ne prinašata prednosti. Rezultat merjenja molskih mas polimerov je odvisen od števila senzorjev v detektorju sipanja svetlobe in ne od delovnih kotov. Senzor z nizkim delovnim kotom ima slabo razmerje signal/šum v vodnih raztopinah, kar je bistveno za naravne polimere. Predlagam, da se zahteva glasi »Detektor sipanja svetlobe z visoko občutljivostjo z vsaj dvema senzorjema kotne odvisnosti sipanja svetlobe, en od katerih je pri delovnemu kotu 90 °«

4. Zahteva 7: »Območje nadzora temperature detektorja 20 - 65 ° C (za detektorje in med detektorji)« - prosim, da se zahteva briše, oz. specificira za detektorja, delovanje katerih pri višjih temperaturah lahko izboljša rezultate (viskozimeter in diferencialni detektor refrakcijskega indeksa), pri čimer se temperatura omeji na 55 °C za DRI in 65 °C za viskozimeter.

5. Zahteva 11: »Opremljenost z avtomatskim vzorčevalnikom z območjem nadzora temperature (4-60ºC), z visoko natančnostjo vbrizgane prostornine« - prosim, da se spremeni zahteva po termostatiranju vzorcev na relevantne delovne temperature (4 - 40 °C).

6. Zahteve 13 - 19, 22 (kolone) - zahtevajo se kolone določenega proizvajalca s komercialnimi imeni. Prosim, da se zahteve spremenijo tako, da se lahko ponudijo ekvivalentne kolone drugih proizvajalcev.

7. Zahteve 23, 24 (standardi) - prosim za obrazložitev zahteve »ozko + široko« in natančno določitev specifikacij standardov.

8. Zahteva 27: »Usposabljanje strank Viscotek« - omenjeno je komercialno ime programske opreme proizvajalca Malvern, kar je nedopustno. Prosim, da se zahteva briše, oz. spremeni v »Usposabljanje strank za delo s sistemom«.


ODGOVOR

Spoštovani.

Naročnik podaja naslednji odgovor in pojasnila vezana na zastavljena vprašanja v sklopu 1:

1. Zahteva 3 / Requirement 3:

Za izračune končnih rezultatov bomo združili podatke iz Light scattering detektorja in RI kot detektorja za koncentracijo, zato je izredno pomembno da je valovna dolžina obeh LS in RI detektorjev ista. Zaradi tipa naših vzorcev mora biti valovna dolžina v rdečem območju, zato je za naročnika sprejemljiv razpon valovnih dolžin od 625 - 670 nm. / As we will combine the light scattering data with data from the RI as concentration detector and use both sets of information in our calculations it is of great importance that light sources of the RI and LS have the same wavelength. Due to nature of our samples, the light source needs to be in the red region, and we will accept all sources that are within 625 - 670 nm range.

2. Zahteva 4 / Requirement 4:

Za naročnika je sprejemljiv predlog spremembe območja valovnih dolžin za UV detektor, zato se zahteva sedaj glasi: UV/Vis z valovno dolžino v območju od 190 do 700 nm. / We accept to change the range to 190 - 700nm.

3. Zahteva 5 / Requirement 5:

Za izračune končnih rezultatov bomo združili podatke iz Light scattering detektorja in RI kot detektorja za koncentracijo, zato je izredno pomembno da je valovna dolžina obeh LS in RI detektorjev ista. Zaradi tipa naših vzorcev mora biti valovna dolžina v rdečem območju zato bomo sprejeli razpon valovnih dolžin od 625 - 670 nm. Prav tako želimo, da LS detektor meri intenziteto razpršene laserske svetlobe čim bližje kotu 0° in s tem omogoča, da je vrednost izračunane molekulske mase zelo blizu realni vrednosti molekulske mase molekul (Zimm plot, y-intercept). Lahko sprejmemo manjše napake pri izračunu molekulske mase, zato dovoljujemo dva kota detekcije od katerih je eden 90° drugi pa 10° ali manj. / As we will combine the light scattering data with data from the RI as concentration detector and use both sets of information in our calculations it is of great importance that light sources of the RI and LS have the same wavelength. Due to nature of our samples, the light source needs to be in the red region, and we will accept all sources that are within 625 - 670 nm range. Furthermore, the LS detector should be able to measures the intensity of light scattered at an angle that is as close as possible to 0° in order that the calculated molecular weight will be very close to the actual molecular weight of the molecule (Zimm plot, y-intercept). We can accept slightly bigger errors in calculated molecular weight and alter the detection angle requirement to 90° and 10° or lower.

4. Zahteva 7 / Requirement 7:

Vsi štirje detektorji (popolnoma integriran RI, Light scattering, UV in viskozimeter) naj bodo v istem temperaturno kontroliranem ohišju, saj je s tem dosežena minimalna razdalja med detektorji in tako minimizirana možnost band broadening-a in tailing-a. Za naročnika je sprejemljiva razširitev temperaturnega razpona za ohišje, kjer so locirani vsi detektorji, na 20 - 55°C. / Fully integrated RI, Light Scattering, UV detectors and viscometer detectors housed in a single temperature-controlled compartment with absolute minimal distance between the detectors will minimize the level of band broadening and tailing. We accept to alter the detector compartment temperature control range to 20 - 55°C.

5. Zahteva 11 / Requirement 11:

Naročnik spreminja temperaturno območje avtomatskega vzorčevalnika na 20 - 55°C, kot velja za ohišje z detektorji. Zgornja meja temperature je potrebna za izboljšanje disolucije različnih polimerov. / We will change the temperature range to 20 - 55°C as for the detector compartment. The upper limit of autosampler temperature is needed to improve the dissolution of different polymers.

6. Zahteve 13 - 19, 22 (kolone) Requirements 13 - 19, 22 (rows):

Specificirane kolone so bile izbrane na podlagi dobrih rezultatov, ki smo jih dobili z opravljenimi meritvami naših vzorcev. S tem smo potrdili ustreznost kolon za naš tip vzorcev. Za naročnika so sprejemljive kolone tudi od drugih proizvajalcev, dokler usterzajo navedenim tehničnim specifikacijam. Naročnik je namreč v zvezi s tem tudi v razpisni dokumentaciji v poglavju Tehnične specifikacije določil, da blago, ki s svojim opisom v tehničnih specifikacijah kaže na točno določeno blago ali blagovno znamko, tip ali proizvajalca, se skladno s šestim odstavkom 68. člena ZJN-3 obravnava kot blago z obvezno dodano navedbo »ali enakovreden«, kot sinonim kakovostne ravni blaga. / The specified columns were chosen because they were already tested on our samples and gave us satisfying results. For our type of samples these columns are the right selection. We will accept columns from other providers as long as they meet the requested specifications. In this regard as well, the contracting authority also stipulated in the tender documentation in the chapter Technical specifications that In accordance with paragraph 6 of Article 68 of the ZJN-3, goods which, with their description in the technical specifications, indicate exactly the specific goods or brand, type or manufacturer, are treated as goods with a mandatory addition of the words "or equivalent" as synonyms of the quality level of goods.

7. Zahteve 23, 24 (standardi) / Requirement 23, 24 (standards)

Standardi, ki se bodo uporabljali za kalibracijo naj pokrivajo območje od 1kDa do 4MDa. / Standards used for column calibration should cover the range from 1kDa to 4MDa.

8. Zahteva 27 Requirement 27:

Naročnik spreminja zahtevo tako, da se ta glasi: Zagotovljeno naj bo izobraževanje uporabnikov./ The Contracting Authority amends the request as follows: Customer training should be provided.

Ponudniki so dolžni zgornja pojasnila in spremembe za sklop 1 v polnosti upoštevati pri oddaji ponudbe. Naročnik ne bo posebej objavljal popravka Tehničnih specifikacija za sklop 1, zato predmetni odgovori predstavljajo sestavni del razpisne dokumentacije v zvezi z javnim naročilom za sklop 1. / The tenderers are obliged to fully take into account this answers and changes for lot No. 1 when submitting the tender. The Contracting Authority will not specifically publish the revision of the Technical Specifications for Lot 1, therefore the subject answers are an integral part of the tender documentation related to the public procurement for Lot 1.

VPRAŠANJE
Dear Sir or Madam,

We would like to bid the premium system for determination of absolute molar mass of polymers. It utilizes multi-angle light scattering, rather than solely low-angle light scattering and right-angle light scattering. As the esteemed customer aware of, the key equation for true molecular weight determination includes form factor P(theta), which describes the scattered lights angular dependence and depends on the size and structure of the scattering molecules. LALS approach with theta 0 simplifies equation and does not apply fitting of P(theta), that dramatically decreases accuracy of molar mass determination. Plotting Zimm plot with signals of multiple detectors is much more accurate, than using just low-angle light scattering data. Moreover, LALS approach is especially prone to the adverse scattering effects caused by particulate matter, like dust in the solvent, or column shedding. The signals from such particulates often mask or distort the measurements of the solute of interest. We kindly ask the customer to revise the requirement 5 and allow possibility to bid MALS detector without required specification of the low angle detector.

Best regards


ODGOVOR

The change request is not acceptable to the contracting authority. To get the absolute molecular weight of the different conformational macromolecules, low angle light scattering detector is necessary. Low angle detector provides the information about the static scattered light intensity which is then coupled with the polymer concentration determined by the DRI detector would provide the appropriate weight average molecular weight values (Mw). Having a LALS detector would allow to get the information about the potential aggregates even if they exist in low concentration within the sample.

Kind regards.
