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.

Condition

Column Newcrom B, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O – 10/90%
Buffer AmFm pH 3.0 Gradient  5 – 60 mM 15 min
Flow Rate 1 ml/min
Detection CAD

Description

Class of Compounds Pesticides, Herbicides, Fungicides, Insecticides
Analyzing Compounds Aminomethylphosphonic acid (AMPA), Bialaphos, Glyphosate, Phosphorous acid H3PO3, Fosetyl-Al, Bromide, Chlorate, Perchlorate, 3-Methylphosphinicopropionic acid (MPPA), Bromide

 

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).

Condition

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

Description

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.
