Pure gases are essential for trouble-free chromatography. Oxygen and moisture affect the stationary phase of the often expensive columns. The amount of stationary phase (film thickness x column length) in a capillary column is already relatively less than when using packed columns. But even with packed columns, you will experience a shift in retention times and peak shape when the stationary phase is affected by moisture and oxygen. With the advent of “Fast-GC”, purity plays an even greater role. For fast gas chromatography you need columns with a smaller internal diameter and often a thinner film. Instrument Solutions offers you solutions to get the gases to the GC column as clean as possible.
