Gas Mixture
Mixtures are manufactured using high precision gravimetric scales
combined with the state of the art blending system. Automated Pre &
Post fill cylinder treatment ensures greater stability of the gas mixture.
Mixture Grades
Primary Standard grade
Precisely blended mixtures prepared by the most advanced gravimetric
techniques, using NIST traceable weights for calibrating the high
precision scale. Minor components are traceable to NIST Standard
Reference Material. The gas mixture is Dual certified by Lab analysis
report.
Certified Standard grade
A specialty gas mixture (calibration gas) used as a comparative standard
for analytical instrumentation is referred to as a Certified Standard.
Certificate specifies the gas concentration, traceability to primary
standard, blend tolerance & analytical certification accuracy.
Environmental mixtures
Gas mixtures used for the calibration of emission monitoring equipment.
These mixtures are manufactured to stringent EPA specifications and
certified using NIST traceable SRM.
Medical application mixtures
Specialty medical gases for the health care industry primarily used in the calibration of diagnostic instrumentation, as
breathable gases for testing purposes, and surgical support applications.
Blood Gas Calibration standards
Pulmonary Function Testing Mixtures
Aerobic Mixtures
Anaerobic Mixtures
