HPLC Separation of Polar Pesticides on Newcrom B Column
November 19, 2020
Pesticide is a more generic term that includes herbicides, fungicides and insecticides in its definition. Herbicides are used to control unwanted plants, they are also known as weedkillers. Insecticides are used to kill insects. Fungicides are used to kill parasitic fungi. All are heavily used in agriculture. By using HPLC, many different pesticides can be separated and their retention characteristics controlled using the Newcrom B mixed-mode column.

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
