AI Contract Overview

The US Geological Survey plans to award a purchase order to LI-COR Environmental Division for a LI-6400R Portable Fluorescence and Gas Exchange System Package, along with specific accessories. This advanced system is designed for field measurements of biological soil crusts, plant photosynthesis, and soil respiration, with a particular emphasis on field portability and operation under harsh and extreme weather conditions. The system incorporates IRGA units at the chamber level for both leaf cuvette and soil respiration chambers and allows automatic, independent variation of CO2, H2O, light intensity, and temperature. It supports simultaneous gas exchange and chlorophyll fluorescence measurements under controlled conditions and features onboard analysis software for in-field data processing. Key technical specifications include a stable integrated light source with an output spectrum that remains constant with varying light intensity, a fully sealed membrane data entry pad, and an integrated calculation system, eliminating the need for an additional portable computer. The system design prevents pressure gradients that could affect flux estimates, and no adapters are needed to manually position the fiber optic in the sampling head. A separate fluorometer system piggyback is not acceptable due to portability requirements. The system's internal light source must operate independently without supplemental lighting or batteries. No formal solicitation will be issued, but interested parties may submit capability statements and product specifications to the Contracting Officer by the anticipated award date of August 18, 2003.

Full Description

The US Geological Survey intends to award a purchase order to LI-COR Environmental Division of Lincoln NE for a LI-6400R Portable Fluorescence and Gas Exchange System Package and accessories. The LI-6400 will include P/Ns LI06400, 6400-40, 6400-01, 6400-02B, 9901-013, 3 ea 9964-037. Accessories include 6400-09, 6400-19, 6400-03 6400, 6400-70, assorted gaskets, nuts, bolts, and shipping. This system is required for field measurements of biological soil crust and plant photosynthesis and soil respiration. The system must be field portable and operate in harsh, extreme weather conditions. It must contain IRGA units at the chamber level in the leaf cuvette and soil respiration chamber. The system must allow automatic and independent variation of CO2, H2O, light intensity and temperature. It must be capable of simultaneous gas exchange and chlorophyll fluorescence measures under controlled conditions, and have on-board analysis software capable of in-field data analysis. Output spectrum of the integrated light source must not change with light intensity. It must possess a fully sealed membrane data entry pad and integrated calculation system, and be able to function without an additional portable computer. The system shall not impact flux estimates by potentially creating pressure gradients. No adapters shall be required to manually position the fiber optic in the sampling head. Separate fluorometer system piggyback on the gas-exchange system is not acceptable for field portability. The system must possess a internal light source which operates without supplemental lights and batteries. No solicitation will be issued. Interested parties may submit a capability statement and product specifications to the Contracting Officer contact@example.gov Anticipated award date: August 18, 2003. See Note 22.
