Description
The above referenced solicitation is hereby amended to incorporate technical changes and extend the due date for quotations. 1. The due date for quotations is hereby changed as follows: FROM: July 22, 2009 at 3:30 PM Eastern Time; TO: September 2, 2009 at 3:30 PM Eastern Time. 2. The following changes are hereby incorporated and made a part of the solicitation: 2.1 Line Item 0001, Specification 2, is hereby amended to delete the requirement to detect N2O in real air and change “real air sample” to “dried real air sample”. Specification 2 is changed to read as follows: FROM: 2. The instrument must be capable of a detection limit of 5 ppt for oxygen, water, and carbon dioxide in nitrogen; must be able to identify and quantify (signal a minimum of 10 times above detection limits) Nitrous Oxide (N2O), carbon tetrachloride (CCl4) freon 11 and freon 12 in a real air sample (along with all other major constituents); must be able to identify and quantify nominal 50 ppb Sulfur Dioxide (SO2). The nominal 50 ppb SO2 signal from a stable and reliable source must give a standard deviation of less than 5 % relative from 5 minute averaging. Day to Day variability of the signal from a 50 ppm SO2 source (standard deviation of 4 daily measurements) shall be less than 5% relative. TO: 2. The instrument must be capable of a detection limit of 5 ppt for oxygen, water, and carbon dioxide in nitrogen; must be able to identify and quantify (signal a minimum of 10 times above detection limits) carbon tetrachloride (CCl4) freon 11 and freon 12 in a dried real air sample (along with all other major constituents); must be able to identify and quantify nominal 50 ppb Sulfur Dioxide (SO2). The nominal 50 ppb SO2 signal from a stable and reliable source must give a standard deviation of less than 5% relative from 5 minute averaging. Day to Day variability of the signal from a 50 ppm SO2 source (standard deviation of 4 daily measurements) shall be less than 5% relative. 2.2 Inspection and Acceptance criteria is hereby amended to remove the requirements for N2O, change “real air sample” to “dried real air sample” and add that “dry real air” will be used for the tests. Inspection and Acceptance Criteria is changed to read as follows: FROM: INSPECTION AND ACCEPTANCE CRITERIA Inspection will be done at the NIST facility upon completion of installation. The APIMS must demonstrate detection limits of 5 ppt for oxygen and carbon dioxide in nitrogen at the NIST site using a NIST approved cylinder gas source. NIST shall provide the cylinder gas source. Analysis of real air must show responses for carbon dioxide, carbon monoxide, methane, argon, oxygen, water, along with trace components N2O, carbon tetrachloride, Freon 11 and Freon 12. The MS/MS capability must be demonstrated on this real air sample showing positive identifications for N2O, carbon tetrachloride, Freon 11 and Freon 12. Additional tests will be done using a NIST gas sample (nominal 50 ppb Sulfur Dioxide) to test stability of the instrument, repeatability, and detection limits. Electron Impact (EI) capability will be tested with a NIST helium sample containing 10 ppm of nitrogen.
