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 columns are standard reverse phase columns with octyldecyl silane chains (C18) attached to porous silica. We have also designed a line of Newcrom R1 columns with a new outer design. This column and corresponding adapter entirely eliminate the need for any high-pressure fittings or tubing as well as minimizing all possible dead volumes. Furthermore, if a leak ever occurs in the high-pressure column inlet, the mobile phase is contained within the column adapter (no external leakage).

Separation of Compounds in TCA Cycle on Primesep D Column

2013-07-03

The citric acid cycle (tricarboxylic acid cycle, Krebs cycle) is a key process in the metabolic pathway by which all aerobic organisms generate energy. Compounds generated during TCA are hydrophilic, acidic compounds. Some of the hydrophilic acids are very strong while others are relatively weaker. All compounds have very low hydrophobicity and do not retain by the reversed-phase mechanism on the C18 or C8 HPLC columns. Citric acid and related products were separated in reversed-phase, anion-exchange mode on the Primesep D mixed-mode column. All hydrophilic, acidic compounds are well separated and demonstrate good shape. This robust method can be used for analysis of components of the TCA cycle and other highly hydrophilic compounds. This method is fully compatible with LC/MS and prep chromatography.

HPLC Separation of Organic Acids

2012-07-10


Primesep D mixed-mode column separates organic acids such as succinic acid, malic acid, MPS and butanesulfonate by a mixture of anion exchange and reversed phase mechanisms. Retention times can be changed by adjusting the percentage of acetonitrile in the mobile phase. This can not be done by traditional ion-exchange and ion-exclusion chromatography. The HPLC separation uses a mobile phase of water, acetonitrile (MeCN, ACN) and ammonium formate as a buffer, making the method MS-compatible. Can also use UV detection at 250 nm.

HILIC Separation of Carboxylic Acids

2008-08-22

Hydrophilic acids are separated on Obelisc N mixed-mode HILIC column. Seven carboxylic acids are separated based on their polarity and pKa values. Changes in ionization states of acids and stationary phase can be used to control elution order of organic and inorganic acids.

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.
