Gas Group in Chemical Metrology Section is responsible in ensuring gas analysis and gas measurement in the country is traceable to gas reference materials.
Gas Calibration
Gas Calibration Laboratory provides calibration of gas analyzers and gas detectors. Multi-component gas mixtures are used to calibrate various types of these device.

Gas Analysis
Gas Analysis Laboratory is equipped with Gas Chromatograph with various type of detectors; for example GC-FID, GC-TCD, GC-SCD, GC-ECD, GC-MS and GC-PDHID, which is an ideal tool to analyse gas samples and enabling our end users to determine the amount of different gaseous in a gas mixture.
