Thin-layer chromatography (TLC) was widely used in the 1960s and 1970s for pesticide residue analysis, but only to a limited extent since gas–liquid chromatography (GLC) and high performance liquid ...

Last time, we looked at the practice of 'measuring' in analytical chemistry. We explained how chemists determine the amount of a substance and evaluate the reliability of those numerical values ...

THIN-LAYER CHROMATOGRAPHY (TLC) has long been a staple of the organic laboratory, and its silica-on-glass plates are familiar even to undergraduate chemistry majors. But for advanced applications, TLC ...

Chromatography is relied on by many disciplines as a method of separating the components of a mixture. The basic idea of the process is that distinct compounds have different levels of solubility, ...

Humans have had a significant effect on the natural world. Our activities have had wide-reaching and long-lasting consequences for the planet. Pollutants can be found in all environments, and come ...

Chromatography is a process for separating components of a mixture for analysis. This is a component of our small molecule analysis testing and plays a critical part in identifying and quantifying ...
