Total petroleum hydrocarbons (TPH) is a term used to describe a large family of several hundred chemical compounds that originally come from crude oil; the main and most specific part of these compounds are non-polar and slightly polar hydrocarbons of the aliphatic, aromatic and alicyclic structure. These compounds are harmful to humans and animals if absorbed through the skin, ingested, and inhaled thus claiming the analytical control of THP content in water as a global ...

Selerity SFC Custom Applications: Selerity SFC Custom Applications offer distinct advantages over gas chromatography (GC) and liquid chromatography (HPLC) when: Compounds are not volatile enough for GC without derivatization. Compounds do not have chromophores suitable for UV detection under HPLC conditions. Compounds are unstable at typical GC temperatures. Universal detectors such as the flame ionization detector (FID) are desired that are not available for ...
