CALIBRATION STRATEGY

11 InGOS General Assembly

Bremen, 11th-14th March 2013

• 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)
