Gas chromatography is a very useful machine for a diverse range of research and work. It is used in the biomarker research, forensic science, pharmaceutical industry, organic geochemistry field, etc. The gas chromatography is an expensive machine. The cost is almost 50 million Japanese yen. In Bangladesh, there is no gas chromatography-mass spectrometry stand-alone machine! It’s really surprising. For advanced research, we need that machine. In the pharmaceutical industry we have a gas chromatography machine but not in the educational or research institute.
