Gas monitoring instruments and systems for stack testing according to EPA test method 320

by Gasmet Technologies Oy     based in Helsinki, FINLAND

The United States Environmental Protection Agency (EPA) has two stack testing methods for FTIR gas analyzers. Method 320 is an FTIR method for measuring wide range of organic and inorganic pollutants. Method 321 is a specific version for measuring hydrogen chloride HCl at cement kilns producing Portland cement. These methods define a quality assurance and control processes for verifying the accuracy of the results. The requirements for analytical equipment and software are defined on 40 CFR Part 60 Appendix B Performance Specification 15. Gasmet™ Gas Analyzers and Calcmet™ software have been designed to take the requirements of the performance specification into account.
