TVA2020 Instruction Manual

Thermo Fisher Scientific

The concentration calculation is defined as the process that transforms a
detector count into a displayed final concentration. The process is as
follows:

DETECTOR COUNT TRANSLAT ED INTO A STANDARD DET ECT OR CONCENT RAT ION
USING A DET ECT OR COUN T VS. DETECTOR CONCENTRATION CALIBRATION CURVE.

STANDARD DETECTOR CONCENTRATION IS CORRECTED TO A SPECIFIC GAS USING
T HE INSTRUMENT RESPON SE FACTOR.

SPECIFIC GAS CONCENT RAT ION IS BACKGROUN D C ORRECTED (IF ENABLED)

INSTRUMENT RESPONSE FACTOR AND BACKGROUND CORRECTED C ONCENTRA-
T ION IS RF CORRECTED USING THE CURRENT ROUTE ENTR Y RF ( IF ANY)

FINAL CONC ENTR ATION READING
