NASA's National Aeronautics and Space Administration (NASA) intends to procure a G2131-I Gas Analyzer through a sole source contract with Picarro Inc., as it is the only manufacturer capable of providing compatible equipment for existing NASA instruments. The analyzer is designed for high-precision isotope measurement of delta[13]C from CO2, as well as measuring concentrations of CO2 and CH4 in ambient air, which is crucial for environmental monitoring and research. The procurement includes freight services, calibration for isotopic performance, and on-site installation and training, with an estimated delivery lead time of 8-16 weeks after order receipt. Interested organizations must submit their capabilities and qualifications in writing to Felecia Lorraine London at Felecia.l.london@nasa.gov by 11:59 a.m. Eastern Standard Time on July 26, 2024, to be considered for this opportunity.
