Arsenic Speciation in Feed Stocks

Arsenic Speciation Made Simple

Hamilton PRP-X100 is a durable column material designed to provide high-efficiency anion exchange separations for arsenic speciation in apple juice and rice and other water and food sources.

Introducing the Hamilton PRP™-X100 for Arsenic Speciation

Arsenic Speciation Made Simple
Organic arsenic compounds added to feed stocks of chicken and poultry pose serious environmental and ecological threats. National and worldwide health organizations, such as the United States Environmental Protective Agency and the US Food and Drug Administration have recently implemented more stringent concentration limits for Arsenic species in drinking water and foodstuffs.

Analysis of arsenic species is made challenging due to diverse sample matrices. To circumvent these problems, an HPLC-ICP-MS method has been developed. Resolution of Arsenic compounds is achieved by ion-exchange chromatography on Hamilton PRP-X100, a 55% cross-linked polystyrene-divinylbenzene copolymer functionalized with quaternary ammonium anion-exchanger groups.  Detection accomplished by inductively coupled plasma-mass spectrometry.

Easy Ion Determination

Hamilton PRP-X100 ion chromatography columns are the easy way to separate inorganic ions. You can use these columns with any existing HPLC or ion chromatograph to easily determine anions in almost any sample matrix including: air, water and soil.
