Troubleshooting of High Performance Liquid Chromatography (HPLC)
There are many test instruments used in the laboratory, and high-performance liquid chromatography (HPLC) is one of them. The instrument is based on classical chromatography, citing the theory of gas chromatography, and technically it changes the traditional mobile phase to high-pressure delivery. This article will introduce the principle and application, characteristics, failure causes, and treatment…
Is Ion Chromatography (IG) the Best Chromatograph?
Ion Chromatography is a type of high-performance liquid chromatography (HPLC), which is a liquid chromatography method for analyzing anions and cations. Like HPLCIC exploits the inherent affinity of ion pairs for the “eluent” (usually buffered water) and the “stationary phase” (porous solid support with charged functional groups). In a narrow sense, ion chromatography is a chromatographic method…
23 Knowledge of Gas Chromatography
Gas chromatography is a chromatographic technique that separates and analyzes compounds that are easy to volatilize without being decomposed in organic chemistry. Typical uses of gas chromatography include testing the purity of a specific compound and separating the components of the mixture (and at the same time determining the relative content of each component). In some…
What Is chromatography? Principle ＆ Application
Chromatography is a device used for chromatographic separation and analysis. It is a high-performance physical separation technology. When it is used in analytical chemistry with an appropriate detection method, it is called chromatographic analysis. Chromatography includes a sampling system, detection system, recording, and data processing system, temperature control system, and mobile phase control system. Modern chromatographs…
