Using the optimum speciality gas and equipment when performing Supercritical Fluid Chromatography (SFC) will greatly improve the accuracy of your results.
SFC is often used to analyse low concentrations of compounds and high molecular weight molecules. It is commonly used in pharmaceutical drug analysis, as well as in the analysis of food, explosives, petroleum, polymers and propellants.
SFC is similar to gas chromatography and liquid chromatography, but uses liquid Carbon Dioxide as the mobile phase so the flow path is highly pressurised. Since SFC is often used to analyse low concentrations of compounds, the purity of the CO2
is important. SFC can utilise a variety of detector methods including Flame Ionisation Detector, Flame Photometric Detector, Electron Capture Detector and Mass Spectrometer, so the correct detector gas is also required (please see Gas Chromatography
for information on the gases required for various detectors).
Our range of Experis® ultra high purity gases offers you the optimum gas for your SFC requirements. Don’t forget your choice of cylinder equipment also affects your analytical results. Our range includes high quality cylinder regulators, manifolds, valves and purge systems which will help to optimise the smooth operation and accuracy of your analysis.
The recommended gas for this application is listed below. If you require any additional advice on the right purity grade for your needs, please contact us.
