Technical NotesUnderstanding the terminology associated with chromatography is important in order to understand your application. This technical note aims to provide clarity on some of the most commonly used terms within the industry.
Technical NotesThere are a variety of reasons why we may need to prepare a sample before it can be analyzed, some of the most common reasons are cleaning up the sample, increasing the concentration of the target analyte, switching the sample solvent or matrix and derivatization of the analyte.
Technical NotesSolid phase extraction (SPE) is a technique that is used to clean up and concentrate samples prior to analysis by gas chromatography (GC) or high performance liquid chromatography (HPLC).
This often involves the use of SPE cartridges which are cartridges that contain a chromatographic sorbent bed, the analytes will remain on the sorbent bed and the sample matrix liquid will
Technical NotesLLE is perhaps one of the oldest and most widely used sample extraction techniques, it has applications across many different industries including pharmaceutical, pesticide and forensics.
LLE can also be used in the environmental and food industries for numerous applications – such as the analysis of semi-volatile organic compounds.
Technical NotesDerivatization extraction can increase the detectability of the target analyte. It is also able to allow for the analysis of compounds which are not directly amenable because they may have inadequate volatility or stability.
How to GuidesGas Chromatography (GC) is an analytical technique applied to separate and identify the chemical properties within a sample.
How to GuidesChromatography is an analytical technique used to separate the components, or solutes, within a mixture. First, the mixture gets dissolved in or mixed with a mobile phase (gas or liquid), which is a going to move or flow through the system.
