Separation type: Liquid Chromatography Mixed-mode
Catecholamines are neurotransmitters that generate the ‘fight-or-flight’ responsein the body. The 3 main catecholamines are epinephrine (also known as adrenaline), norepinephrine, and dopamine, and they are produced by the adrenal glands.
These 3 catecholamines can be detected in the low UV regime. Using a Newcrom AH mixed-mode column and a mobile phase consisting of almost entirely water with either a phosphoric (H3PO4) acid or ammonium formate (AmFm) buffer, the catecholamines can be retained, separated, and measured. This analysis method can be UV detected at 275 nm with high resolution. The latter mobile phase (utilizing AmFm) is compatible with Mass Spectrometry.

Application Column
Newcrom AH
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
