66 -- NITRIC OXIDE ANALYZER FOR GAS AND LIQUID SAMPLES NOTICE OF INTENT TO SOLE SOURCE. The National Institute for Occupational Safety and Health (NIOSH), iin Morgantown, WV, has a requirement for a nitric oxide (NO) analyzer for measurement of NO in exhaled breath and measurement of NO in liquid samples. The NO analyzer must use chemiluminescence technology and have a detection limit of less than 1 ppb for measuurement of NO in exhaled breath. It is necessary for the instrument and software obtained to be able to perform measurements of exhaled NO consistent with recently-published guidelines suggested by the American Thoracic Society (ATS). The Government requires an instrument for measurement of NO in both gas and liquid samples with an inhalation scrubber system to eliminate inhalation of NO from leading to falsely elevated exhaled NO values. Also required is a calibrated flow restrictor for use in single breath analysis of NO and software including programs for liquid sampling, restricted exhaled breath measurement, breath by breath sampling and bag sampling. The unit must be small and easily transportable to work sites for studies. The Government intends to negotiate on a sole-source basis with the Sievers, Plumsteadville, PA.
