- Description
- Attachment 6 Attachment 5 Attachment 4 Attachment 3 Attachment 2 Attachment 1 Amendment 3 The solicitation has been amended which makes changes to the requirements of the solicitation and evaluation scheme. Questions and Answers: 1. From a scientific point of view the low end of the mass range, in this case 5 m/z, has nothing to do with the detection of high molecular weight compounds. The 5 is in essence a lock out specification for a single vendor as some vendors will start at 2 m/z, others 5, and still others 15. The reason for the variability is that there are absolutely no compounds detectable below 15 m/z. Response: The solicitation has been amended to revise the mass range so it is not a lockout specification. 2. As currently stated the bid requires "The system ion source shall be capable of both Electrospray Ionization (ESI) and Atmospheric Pressure Chemical Ionization (APCI). The Electrospray Ionization (ESI) source shall allow heated gas up to a temperature of 750°C for optimal desolvation." Optimal desolvation temperature is a function of ion source design and has no universal relevance when comparing vendors who manufacture triple quadrupole mass spectrometers. The ideal temperature for desolvation is affected by source volume, temperature, volume of gas flow utilized, the dynamics of the gas flow, volatility of the solvents utilized and the overall efficiency by which these individual aspects permit desolvation. The reason for "optimal desolvation" is to facilitate sensitivity which has been clearly defined in other specification relevant to this bid. In addition, heated gas has relevance to both ESI and APCI although the specification requires only the ESI gas to be heated. We would respectively request that the temperature specification be removed in its entirety as it only services as an experimentally irrelevant lockout specification for one specific vendor, with an older source design, that happens to require such high temperatures to attain the stated sensitivity specifications contained in this bid. Response: The solicitation has been amended to address this concern. All questions have been answered/addressed with this amendment.
