THÔNG TIN HỮU ÍCH
VGM's (Various Gas Mixtures) are proven internal analytical standards used in our methods development at Vietnamgas Specialty Gases & Equipment. We offer these internal analytical standards as a low cost alternative for system calibration when only a small amount of calibration gas is required. It can assist with peak identification, retention time, co-elution analysis and other methods development techniques. If you don't see what you're looking for here, call us. We have hundreds of available standards. Maybe we have something to meet your requirements. If not, we can custom manufacture a standard to meet your specific needs.
The 14L and 20L VGM Natural Gas Standards require a CGA 160 Series 300 Single Stage Specialty Gas Pressure Regulator.
