Condition 1
Column Newcrom B , 3.2×50 mm, 5 µm, 100A
Mobile Phase MeCN/H2O – 20/80%
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.

Select options

Primesep D

The Primesep family of mixed-mode columns offer a wide variety of stationary phases with an unprecedented selectivity in the separation of a broad array of chemical compounds and in multiple applications. Corresponding Primesep guard columns are available with all stationary phases and do not require holders. SIELC offers a method development service which is available for all customers. Ask about our special custom LC-phases tailored for specific separations.
