HPLC Method for Determination of Histamine on BIST A+ Column by SIELC Technologies

Histamine dihydrochloride, also known as Ceplene, is a medication with the chemical formula C₅H₁₁Cl₂N₃. It is used primarily to prevent a relapse of acute myeloid leukemia. Other pharmaceutical applications include as a topical analgesic to treat arthritis, aches, bruises, sprains, and strains. Brand names it is sold under include Australian Dream and Alo.

Histamine dihydrochloride can be detected in the low UV regime. Using a BIST A+ column and a mobile phase consisting of water and Acetonitrile (MeCN) with an ammonium formate (AmFm) buffer, Histamine chloride can be retained, separated, and analyzed. This analysis method can be detected and is compatible with Mass Spectrometry (MS), ELSD, and CAD.

HPLC Separation of Histamine and Phenethylamine on Primesep C Column

August 7, 2010

View Application

Histamine is a basic compound that acts like neurotransmitter. Phenethylamine is a natural amine alkaloid psychoactive compound with stimulant effects. It forms by enzymatic decarboxylation of phenylalanine, and also acts as neurotransmitter. Both compounds are separated in one HPLC run on Primesep C and Primesep 200 columns by reversed-phase cation-exchange mechanism. Primesep C provides shorter retention time and histamine and phenethylamine can be separated within 5 minutes. Primesep C and Primesep 200 columns do not require ion-pairing reagent as it is attached to the surface of Primesep silica gel. Method can be used for analysis of these two compounds in plasma, blood and urine with UV, ELSD, CAD or LC/MS detection.
