1.) The factory testing and factory test report is hereby removed from the solicitation in its entirety.

2.) Required submission # 1 is hereby amended as follows:

FROM:

Documentation and product literature, which clearly demonstrates that the equipment being quoted meets or exceeds the specifications, identified herein;

The quoter must supply data to support the performance requirements provided in its documentation and product literature. Specifically the quoter must support the following:

• Detection limit of 50 ppb for CO2 in nitrogen or synthetic air (20.9% O2 / N2 balance).

Demonstrated by the Absorbance height at 2361.2 ± 0.5 cm-1 (the λmax for CO2) of a 50 ppb CO2 NIST provided standard being at least 2.0 times more than the peak-to-peak noise in the spectral region of 2351 to 2371 cm-1.

• Detection limit of 10 ppb for CH4 in nitrogen or synthetic air (20.9% O2 / N2 balance).

Demonstrated by the Absorbance height at 3085.9 ± 0.5 cm-1 (the λmax for CH4) of a 10 ppb CH4 NIST provided standard being at least 2.0 times more than the peak-to-peak noise in the spectral region of 3076 to 3096 cm-1.

• The signal-to-noise ratio (S/N) improves as the function of the square root of the number of scans co-added (N). The relationship of S/N to N shall be demonstrated by reporting the S/N (in the region 2900 to 3100 cm-1) at 0.5, 1.0, 1.5, and 2.0 hours of co-adding the spectra of nitrogen. The improvement in S/N shall increase a minimum of 1.8 times from 0.5 to 2 hours of co-adding (the expected improvement is 2.0 times).

For each performance requirement, the Contractor must supply the data collection parameters which, at a minimum, must be gas cell pathlength, resolution, number of scans, apodization, and total acquisition time.
