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.

HPLC Analysis of Sulfate and Phosphate Ions on Primesep Columns

October 14, 2010


Inorganic and organic ions are usually analyzed by ion-exchange mechanism. In this application, we used short Primesep B2 and Primesep D mixed-mode HPLC columns to retain and separate phosphate and sulfate ions. Both ions are retained by ion-exchange mechanism. Detection technique for analysis of these anions is Evaporative Light-Scattering Detector (ELSD).

Application Column

Primesep B2

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.

HPLC Separation of Sulfamic and Sulfuric Acid on Primesep N HILIC Column

July 16, 2009

Sulfuric acid (sulfate ions) and sulfamic acid are analyzed in HILIC mode on Primesep N column. Both compounds are hydrophilic in nature and lack UV activity. Compounds are retained by hydrophilic interaction mechanism. Sulfate ion and sulfamic acid are monitored by ELSD. Method can be used for analysis of other inorganic ions.

Simultaneous Determination of Sodium and Sulfate Ions on Obelisc N Mixed-mode HILIC Column

July 16, 2009

Inorganic cations and anions are usually analyzed by two different methods – cation-exchange and anion-exchange. This requires development and validation of two methods. Both ions can be analyzed on mixed-mode HILIC column with ELSD detection. Both ions are retained by combination of HILIC and ion-exchange mechanism.

Condition

Column Obelisc N, 4.6×50 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer AmFm, pH 3.0
Flow Rate 1.0 ml/min
Detection ELSD

 

Description

Class of Compounds
Acid, Hydrophilic, Ionizable
Analyzing Compounds Sodium, Sulfate Ions

 

Application Column

Obelisc N

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.

HPLC Separation of Sulfate and Phosphate Ions on Mixed-Mode HPLC

December 6, 2007

Sulfate and phosphate are separated on Primesep B2 and Primesep D column by anion-exchange mechanism. Because both sulfate and phosphate ions are not UV-active, ELSD is used to monitor separation of both anions. Method can be used to quantitate phosphate and sulfate in various pharmaceutical and chemical formulation, products and solution, drinking and ground water. Retention time is adjusted by increase or decrease of buffer concentrations. Two anions can be retained and separated on a very short column due to strong ion-exchange interaction. Method shows good reproducibility and versatility.

Condition

Column Primesep B2, 4.6×50 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
