APPENDIX V: Guide for Purchasing Standardized Gases
for Calibration
When deciding which standard gases to purchase for calibration, there are some important
considerations that will help guide your purchase:
1) Determination of concentration of the gas to be purchased. The concentration of the
standard gas is the first consideration. It needs to be at a concentration level that is
appropriate for calibration of the instrument.
2) Determination of proper regulator for the standard gas tank. A regulator is needed to
provide a consistent flow of gas to the instrument at a certain rate. At our facility, we
use on-demand regulators that require the pumps within our instruments to pull the
gas from the standardized tank. If this is not an option, other regulators are
acceptable, just use a T-junction when connecting to the instrument to protect the
instrument from damage.
3) Determination of the size of tank to order. Consider how many calibrations can be
performed with the volume of gas purchased. Each calibration for the F-920, 940,
and 960 will take around 0.3 liters of standard gas.
Felix instruments does not sell calibration gases. There are many gas suppliers worldwide, you
may source gas for calibration and verification of our instruments from any gas supplier. Refer
to the calibration chart in our manuals for the gases needed for your specific instrument. We are
providing the following supplier information as a resource. CAC Gas is located in Australia, has
partners worldwide and can ship directly to most locations.
