GMACS Solutions from Air Liquide Fill the Regulatory Void Caused by the Absence of
EPA Protocols
Identifying a growing need for calibration standards in order to comply with pending EPA regulations governing the monitoring of hydrogen chloride, Air Liquide petitioned the EPA to approve a new class of calibration gases named GMACS by the EPA. Acknowledging “the critical need for HCl calibration standards that are not available due to the absence of national or international reference materials to which protocols must be analytically and statistically traceable," the EPA approved the use of HCl GMACS products to calibrate HCl analyzers. GMACS fill the regulatory void caused by the absence of EPA Protocol gases for hydrogen chloride monitoring and provide accurate calibration standards for CEMS commissioning and QA—available now to meet impending PC MACT compliance date (September 2016)
Scott brand GMACS are especially effective when used in conjunction with our new proprietary gas delivery panel complemented by our nitrogen purge and purification panel. Both panels were developed specifically for use with HCl gas mixtures.
GMACS are engineered calibration gases for stationary sources that are subject to compliance under the following EPA regulations:
40 CFR Part 63 Subpart LLL (Portland Cement MACT)
40 CFR Part 63 Subpart UUUUU (Utility MACT)
40 CFR Part 63 Subpart DDDDD
40 CFR Part 60 Subparts CCCC and DDDD
