Optimizing your chromatographic separation starts by choosing the correct column, but this can be a daunting task. Should you borrow from a colleague, root around in the back of the store cupboard or choose your favorites from last time around? Phenomenex has created a step-by-step guide to help you pick both the best GC column, and liner for your needs.

When choosing a GC column, the most common concern is whether you can achieve the desired sample resolution in an efficient period of time. Selectivity, which is determined by the column chemistry, has the biggest impact on resolution. This GC Selection Guide helps simplify the thought process behind choosing the best selectivity for your sample and application.

Furthermore, once you have chosen your desired selectivity, there are three dimension considerations to consider when purchasing a column: length, diameter and film thickness. Choosing the best dimensions for your column further increases separation efficiency and directly affects run times. Whilst there are nominal values which are good to start at with a new sample, the online GC Selection Tool makes choosing the very best dimensions for your needs even easier.

Need any further help? The online GC Liner Finder helps you find the correct liner for your GC system and sample in under a minute, whilst this 5 Phase GC Selection Guide is there to help with all your specific 5 phase needs.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Chromatography Method DevelopmentChromatography method development is the process of designing and optimizing chromatographic techniques to separate and analyze complex mixtures. This includes selecting appropriate stationary and mobile phases, determining flow rates, and optimizing detection methods. Successful method development is essential for high-quality results in fields like pharmaceuticals, food safety, and environmental analysis.

It is widely used in fields like biochemistry, pharmaceuticals, and environmental analysis. By exploiting differences in the interaction of substances with a stationary phase and a mobile phase, chromatography enables precise purification and quantification of compounds. Whether you're working with complex biological samples or industrial chemicals, chromatography is essential for obtaining high-quality results.
