HILIC Separation of Carboxymethylcysteine and Betaine

2008-08-22

In this HPLC method, betaine and carboxymethylcysteine are separated by HILIC mixed-mode mechanism. Betaine and carboxymethylcysteine are very hydrophilic compounds which are not retained on reverse phase columns. Compounds are separated by combination of HILIC and ion-exchange mechanisms. In HIILIC mode, Obelisc N columns allow operating at lower organic concentration for improved solubility of analytes. Method can be used for quantitative or qualitative analysis of betaine and carboxymethylcysteine using ESLD or LC/MS detection. Betaine in chemistry is any neutral chemical compound with a positively charged cationic functional group such as ammonium ion or phosphonium ion (generally: onium ions) which bears no hydrogen atom and with a negatively charged functional group such as a carboxylate group which may not be adjacent to the cationic site. Historically the term was reserved for tetramethylglycine only.

Application Analytes:
Betaine
Carboxymethylcysteine

Application Detection:
UV Detection
ELSD/MS Detection
SIELC Technologies usually develops more than one method for each compound. Therefore, this particular method may not be the best available method from our portfolio for your specific application. Before you decide to implement this method in your research, please send us an email to research@sielc.com so we can ensure you get optimal results for your compound/s of interest.

Obelisc N

SIELC has developed the mixed-mode Obelisc™ columns to be the first commercially available columns with Liquid Separation Cell technology (LiSC™). This cost effective duo can replace multiple HPLC columns such as 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.

Retention Characteristics of Betaine in Mixed-Mode HPLC

2005-05-05

HPLC Application: Retention Characteristics of Betaine in Mixed-Mode HPLC

The retention of the zwitterion betaine on Primesep 200 demonstrates the tunability of Primesep columns. Retention of betaine is altered by acid type, amount of acid in the mobile phase, and the amount of organic solvent. Typical reversed-phase columns do not show this tunability with simple mass spec compatible mobile phases of water, acetonitrile (MeCN, ACN) and trifluoracetic acid (TFA) with evaporative light scattering detection (ELSD).

Application Analytes:
Betaine
Quaternary Amines
Zwitterion

Application Detection:
