High Accuracy Operation
When you are analyzing critical samples, you must allow Explorer to stabilize for
a few hours before performing any runs. You must also calibrate the instrument
immediately before analyzing the critical samples.
Your calibration gas must contain all of the library compounds. The concentration of
the calibration compounds should be close to the concentration of the target
compounds.
You should also run an analysis of the calibration gas before and after running the
critical sample to ensure that the
Explorer was performing correctly during the
analysis. If you calibrated directly from the tank of calibration gas, run an analysis
with
Explorer connected directly to the tank. If you used a gas bag for calibration,
empty and refill the gas bag and then run an analysis using the gas bag as a
sample.
