Tips if Calcmet does not IDENTIFY any gases - 1

A. Visual inspection of Spectra

Identify function will not find any Unknown gases
and it is to be interpreted as a Clean Sample

(refer limitations statement on last page)

Visual inspection of spectra shows peaks not
normal in clean ambient air indicating there is one
or more Unknown gases present.
Run IDENTIFY function - If no gases found refer
next page.
