Specifications include, but are not limited to: • Must be a laser-based spectroscopic analyzer that measures formaldehyde directly (without the interference from other gases or analytes) in ambient air and at ambient air concentrations in real-time and up to the ppm concentration range. • Analyzer must have the ability to correct for water in ambient air. • Analyzer must report continuous (2 seconds) real time formaldehyde concentrations with a limit of detection of 300 partsper-trillion (ppt) or less of formaldehyde over a 1-minute average time. • Analyzer must have the ability to be calibrated or validated by external standard verification gas (include an itemized list for ancillary equipment in the payment schedule). o To have the ability to perform periodic quality control checks, zero checks, and calibrations using gas standards plumbed through a manifold. o Must be able to obtain daily zero (re-zero) corrections for the periodic zeroing of the analyzer. • Provide list of supplies required and pricing in the pricing schedule (e.g. filters, drier kits, maintenance, etc.) • Analyzer calibration drift must be <1.5 ppb over a 72-hour operation period at standard temperature and pressure (STP). • Analyzer must occupy a small footprint to fit an equipment rack. o Dimensions not to exceed (45 cm (w) × 20 cm (h) × 45 cm (d)). • Must be able to operate at ambient temperatures (10 to 35 degrees Celsius). • Sample Humidity less than 99%. non-condensing at 40 degrees Celsius. No drying required. • Must be able to obtain daily zero (rezero) corrections for the periodic zeroing of the analyzer. • Analyzer flow path coating for inactivation is required to prevent losses of analyte along surfaces. • Windows 10 operating system with RS 232, Ethernet, USB options for data output. • Compatible for use with Agilaire Model 8872 Data Logger. o Option of .csv exportable data. • Power Requirements: 100-240 VAC • Response time for formaldehyde: At concentration range of 0–20 ppb (Rise/Fall Time 10–90% / 90–10%) less than 5 sec. SERVICES (include in pricing schedule) • Provide cost for initial training for staff • Must include an annual service plan for five years o Includes phone and email support o Remote diagnostics o Maintenance kit o If replacement parts are required, a quote is to be provided (warranty to cover initial year) o If repairs on the instrument are required, a quote is to be provided (warranty to cover initial year)
