CDC/NIOSH intends to award a sole-source firm-fixed-price purchase order to Block Engineering LLC for a Quantum Cascade Laser with associated detector and thermocooler. The equipment will support NIOSH research to develop a portable real-time monitor for respirable crystalline silica, using aerosol sampling equipment to measure infrared absorption characteristics. Market research identified Block Engineering LLC as the only known source providing a 12.5 µm wavelength tunable laser that meets the required size, weight, and performance for a portable field instrument. Responsible sources that believe they can meet the requirements may submit a quotation or capability information with sufficient technical detail for Government consideration.
