Cylinder Gas Audits

By: Gasl  09-12-2011

Cylinder Gas Audits (CGA's) are required by the 1998 Alberta CEMS Code and must be performed according to section 4.5.4.

Prior to conducting Cylinder Gas Audits, GASL performs a system check to ensure that all temperatures, pressures, and flows are at normal values.

Once checks are complete Cylinder Gas Audits are performed by challenging a CEM System with three protocol gasses at appropriate concentrations, allowing the outputs to stabilize, then recording the DAS output, calculating average responses, and determining the linearity at each different concentration.

GASL performs Cylinder Gas Audits on a wide variety of systems.  With every CGA a detailed report is provided for your records.
