INSTRUMEX High Volume Sampler is based on |
a simple design, standardized by the USEPA, to |
monitor the Suspended Particulate Matter (SPM) |
in ambient air and also simultaneous sampling |
of pollutant gases like SO2, NOx, Cl2, H2S, CS2, |
etc. There gases are analyzed subsequently by |
simple chemistry method to determine |
concentration of specific pollutants. |
