HPLC Method For Analysis Of Dopamine and Serotonin on Primesep 200 Column
March 25, 2022
Separation type: Liquid Chromatography Mixed-mode
High Performance Liquid Chromatography (HPLC) Method for Analysis of Dopamine and Serotonin
Dopamine is a key neurotransmitter and medical stimulant used to treat low blood pressure, low heart rate, and heart attacks. Serotonin is another key neurotransmitter that has pharmaceutical applications – namely as the key ingredient in antidepressant and anti-anxiety medications.These two neurotransmitters can be retained, separated, and analyzed on a Primesep 200 mixed-mode column using an isocratic analytical method with a simple mobile phase of water, Acetonitrile (MeCN), and an Ammonium Formate (AmFm) buffer. This analysis method can be UV detected at 280 nm with high resolution and peak symmetry.

HPLC Separation of Biogenic Amines on Primesep 100 Column
April 30, 2020
Tryptophan is an essential amino acid used in the synthesis of proteins. Tryptamine is structurally similar to tryptophan. Serotonin is a neurotransmitter derived from tryptophan. Dimethyltryptamine and 5-MeO-DMT are psychedelic substances derived from tryptamine. All the compounds have similar structures and can present difficulties to separation in reverse-phase HPLC. They can be separated using the Primesep 100 mixed-mode column in gradient analysis with acetonitrile (ACN) and water mobile phase with ammonium formate (AmFm) buffer, making the method MS-compatible. The amines can also be UV detected at 280nm.

The neurotransmitters dl-DOPA, creatinine, hydroxytryptophan (5-HTP), and serotonin are separated in less than 4 minutes on a short 50 mm Primesep 200 column. The HPLC separation uses a mobile phase of water, acetonitrile (MeCN, ACN) and trifluoroacetic acid (TFA) and UV detection at 250 nm. Ion-pair reagents were not needed for retention of these polar, hydrophilic compounds, instead, a combination of ion-exchange and reversed-phase interactions were used.

Separation of Serotonin, Dopamine, and Related Compounds

Catecholamines are chemical compounds derived from the amino acid tyrosine containing catechol and amine groups. Some of them are biogenic amines. Retention of compounds of the catecholamine pathway is achieved on Obelisc N column. All polar compounds are well retained by combination of HILIC and ion-exchange mechanisms. Obelisc N columns produce very good peak shapes for all analytes. The method is very sensitive to amount of ACN, buffer and buffer pH. The retention time changes with variation of the main parameters. This method can be used for quantitation of biogenic amines and related compounds (homovanillic acid, dihydroxyphenyl acetic acid, serotonin, dopamine, epinephrine, hydroxytryptophan, epinephrine and DOPA) in urine, blood and other biological fluids. Further optimization of this HPLC method can be used during screening and validation. Amines and acids can be analyzed in the same run and retained by a combination of polar organic mode, cation-exchange and anion-exchange modes. Various buffers within specified pH can be employed (ammonium formate, ammonium acetate, sodium phosphate, etc.).

SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters - buffer concentration, buffer pH, and organic modifier concentration - users can adjust the column properties with pinpoint precision to separate complex mixtures.
