SOURCES SOUGHT Photoacoustic black carbon particulate matter mass analyzer for EPA NVFEL ***MADE IN AMERICA*** EPA is seeking to purchase one (1) photoacoustic black carbon (BC) mass analyzer, either in standalone or combined packaging, for measuring the BC concentrations of particulate matter emitted from internal combustion engines. The EPA identified one foreign product from, AVL North America Corporate Services, Inc., that meets the EPA’s required specifications. The specifications for the photoacoustic analyzer are as follows: 1) Ability to measure PM BC mass concentration: a. If not otherwise stated, photoacoustic analyzers shall meet the requirements of 40 CFR Part 1065 and 1066 b. Zero and span drift shall each be less than ± 1% full scale reading over 4 hours. c. must be range configurable for 0.001 mg/m3 to 150 mg/m3 d. analyzer must be accurate to =1% of full scale reading e. analyzer must be repeatable to =1% of full scale reading f. analyzers must have noise =1% of full scale reading g. Linearity verification (e.g., 40 CFR 1065.307) using a BC source h. Sample flow range up to at least 0.001 m3/minute 2) User interface/data control and acquisition software and hardware: a. Hardware i. RS-232, USB, or ethernet port(s) for instrument control and data transfer ii. Front panel user display with appropriately labeled control knobs, buttons, and/or switches iii. Panels with appropriately labeled input gas and sample connectors b. Software i. Able to monitor and log multiple instrument operation parameters (e.g., gas flows, mass concentration, sample gas temperatures and pressures, etc.) ii. Compatible with Microsoft Windows 10 iii. Data output to standardized file format nonspecific to a particular software application (e.g., ASCII or text file format with standard delimiters that do not contain specialized formatting characters) 3) Minimal ambient conditions operational range a. temperature range : 0°C through 30°C b. pressure range : 0.95 to 1.05 bar 4) Dual power (500 watts maximum): a. 120 volt AC, 60Hz, 2 amp b. 24 volt DC, 20 amp 5) Wheeled cart for analyzer for portability 6) Sample lines a. Heated 6 meter b. Heated 3 meter c. Unheated 2 meter 7) 3 Sample probes compatible for use in vehicle and engine dynamometer constant volumes sampling (CVS) systems 8) Minimal impact on facility resources in terms of safety considerations (electrical connections insulated and covered, safety switches, guards for rotating parts, …) This Sources Sought is seeking authorized American products providers that meets or exceeds the above specifications to purchase a photoacoustic black carbon mass analyzer. Point of Contact for this Sources Sought is OAR NVFEL SACO, Contracting Office, email at OARNVFELSACO@epa.gov. Telephone queries will not be honored.
