Buffer H3PO4 – 0.1%
Flow Rate 0.5 ml/min
Detection UV, 275 nm

 


Vanilmandelic, hydroxyindoleacetic and homovanillic acids are metabolites of various neurotransmitters that are used in urine tests to measure the levels of those neurotransmitters in the body. They can be baseline separated on a reverse-phase Primesep D HPLC column by varying the buffers and pH of the mobile phase consisting of water and acetonitrile (MeCN, ACN). UV detection at 230nm.

Condition 2

Column Primesep D, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN
Buffer TFA,  AmFm
Flow Rate 1.0 ml/min
Detection UV, 230 nm

Application Column

Newcrom B

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.

Primesep D

The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.
