HPLC Method for Iodomethane (Methyl iodide) on Newcrom R1 by SIELC Technologies

 

High Performance Liquid Chromatography (HPLC) Method for Analysis of Iodomethane (Methyl iodide)

Iodomethane, also known as Methyl iodide, is a compound with the chemical formula CH3I. It is a volatile liquid that is produced by rice, algae, fungi, and kelp. It is used as a pesticide, more specificly as a pre-plant biocide for a variety of plants. California Department of Pesticide Regulation (DPR) declared that iodomethane is toxic, leading it to no longer being used in Californian soil.

Iodomethane (Methyl iodide) can be retained and analyzed using the Newcrom R1 stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN). Detection is performed using UV.

Separation of Methyl iodide on Newcrom R1 HPLC column

February 16, 2018
Separation of Methyl iodide on Newcrom C18 HPLC column

Methyl iodide can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.

Application Column

Newcrom R1

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.
