Description

1. Time for receipt of offers is extended to 4:30 p.m. on September 19, 2001. 2. Delivery date is extended until November 9, 2001. 3. Change to the specification: DELETE "Software must allow detector gain to be adjusted during an analysis in order to achieve greater sensitivity for low levels of specific elements." 4. The revised specification in its entirety:  Must utilize "continuous flow" design for a simple yet effective analysis of all components required.  The entire volume of gas resulting from the complete combustion of the sample must be analyzed by complete separation in a GC column and detection by TCD (Thermal Conductivity Detector).  Instrument must not employ techniques such as gas splitting, aliquot sampling, dilution, or trapping of gases for subsequent analysis.  Design must permit operational interface capability with isotope ratio mass spectrometers for analysis of stable isotopes of nitrogen and carbon or trace sulfur analyses by Flame Photometric Detector.  Must offer the capability of direct introduction of liquid samples by optional manual or automatic injection devices.  Instrument must use no lead-based reagents for any configuration.  Instrument must offer a detection limit of at least 100ppm for all analyses.
