Traceability Protocol for Certification of Reference Aerosol Generators - Brochure

A reference aerosol generator (RAG) is a device which produces an aerosol of known concentration of an analyte or analytes of interest. Calibration gases have traditionally been used to establish the accuracy of continuous gas monitors. However, no such primary NIST standards exist for analytes in aerosols. Instead, a reference aerosol generator can be used to establish the accuracy of monitors measuring aerosol analytes. A NIST traceable certified reference aerosol generatoris a useful calibration and auditing tool for several types of monitors including particulate matter (PM) continuous emissions monitors (CEMS), multi-metals CEMS, metals continuous fence line monitors (CFLM), and ambient PM10 and PM2.5 monitors.
