HPLC Determination of Chloride, Chlorate and Perchlorate on Newcrom B Column
December 10, 2019
Main source of contamination of environment by perchlorates are rocket fuels, car airbags, and fireworks.
EPA developed regulation of the perchlorate level in drinking water which already adapted by several states.
The most convenient, universal and very sensitive way to measure perchlorate is chromatography.
SIELC developed a simple, rugged, and selective HPLC method which allows to measure perchlorate in different matrices including drinking water.
This method allows to measure simultaneously other chloro containing ions such as chloride, and chlorate.
The method shows high selectivity and specificity.
The mobile phase is a simple mixture of water acetonitrile and ammonium formate.
The column used in the analysis has advanced surface chemistry with long chain holding a terminal positively changed functional group.

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.

HPLC Separation of Chlorate and Bromate Ions
March 27, 2004
Primesep B2 separates chlorate and bromate by an ion-exchange mechanism. The anion-exchange properties of the column allow retention of hydrophilic compounds, and these properties can be adjusted by simply changing the ammonium formate buffer concentration. The HPLC separation uses a mobile phase of water, acetonitrile (MeCN, ACN) and ammonium formate with evaporative light scattering detection (ELSD).
| Column | Primesep B2, 4.6×150 mm, 5 µm, 100A |
| Mobile Phase | MeCN/H2O – 30/70% |
| Buffer | AmFm pH 3.0 |
| Flow Rate | 1.0 ml/min |
| Detection | CAD |
| Class of Compounds | Ions, Hydrophilic, Ionizable |
| Analyzing Compounds | Sodium Chlorate, Sodium Bromate |
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.
