Processor Requirements
Continuously monitor total non-methane
hydrocarbons (TNMHC) in ambient air.
Take action at the 1 ppm TNMHC alarm limit.
Collect samples for speciation offline.
Report the findings.

Bulk TNMHC or Speciation of TNMHC Components?
Online TNMHC analyzers cost as much as speciation
online and offline (contract lab) speciation is an
additional, high cost.

Why not speciate, totalize and eliminate offline cost?

Implement
microFASTTM GC for . . .
Online speciation of the mandated components.
Summation of the TNMHC components to detect the
alarm limit  and for reporting.

Implement smart systems for        
System suitability (validation of results).
Alarming on the basis of results.
Archiving data for reporting and for the historical record.
