This contract was awarded by the National Oceanic and Atmospheric Administration (NOAA) to Picarro, Inc., a manufacturer of specialized gas concentration and stable isotope measurement systems. The $79,523.20 fixed-price purchase order is for the delivery of a gas concentration analysis instrument with a rack mount configuration for NOAA's 2000 series analyzers. This sole-source award was made under the authority of FAR 13.106-1(b)(1) due to NOAA's requirement for Picarro's proprietary technology, which meets the agency's precise measurement needs for monitoring atmospheric levels of carbon dioxide, carbon monoxide, methane, and water. Picarro has previously provided similar cavity ring-down spectrometers, greenhouse gas analyzers, and other analytical equipment to support NOAA's environmental monitoring and climate research programs. This contract award does not have a set-aside designation.
