CALIBRATION STRATEGY • • • •
A working tank (WT) is used: WT - Sample – WT - Sample – etc. 6 working standards (MPI cylinders) used for calibration Currently, calibration every 2.2 days: Tests for lower frequency needed (1 per week?) A target cylinder (Trg) is run three times per day (MPI cylinder) CH4 (ppm)
CO (ppb)
N2O (ppb)
CO2 (ppm)
