Phenomenex’s GC Troubleshooting Guide
10 Mar 2017This white paper provides troubleshooting support for gas chromatography (GC). GC is a common technique used in analytical chemistry, which is used for separating and analyzing compounds that can be vaporized without decomposition. This guide will explain how to deal with common issues such as bleed, drift, and noise through a series of systematic steps, which will lead to improved results and prevention of re-occurrence.

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.Preparative ChromatographyPreparative chromatography equipment is used for purification purposes, separating and collecting compounds eluted from a mixture which can then be subsequently used for further purposes. This can be done in large quantities or small. Preparative chromatography systems are usually low to medium pressure liquid chromatographs that are semi-automated. Explore a range of preparative columns and fraction collectors.

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.

Services are provided from the early stages of drug development and clinical trials through to dossier submission, approval and marketing. Regulatory also includes submission of analytical studies from the pharmaceutical product and safety. ChromatographyChromatography is a powerful technique used to separate and analyze components of mixtures based on their chemical properties. 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.
