In line gas chromatograph

WebbPrinciple of gas chromatography: The sample solution injected into the instrument enters a gas stream which transports the sample into a separation tube known as the "column." (Helium or nitrogen is used as the so-called carrier gas.) The various components are separated inside the column. WebbOur GC training courses cover a range of gas chromatography applications. Taught remotely, we can provide a training solution that will improve your lab workflows — from the basics to advanced techniques. With roughly 300 courses delivered across the UK each year, we are the go-to team for technical support in GC — regardless of your headcount.
