ARSENIC SPECIATION
PSA 10.825 ISOCRATIC LC SYSTEM (HPLC HG AFS) FOR THE SPECIATION OF ARSENIC
The
PSA 10.055 Millennium Excalibur can easily be utilised for arsenic
speciation with the addition of a strong anion exchange
or a C18 ion-pairing separation system. A simple isocratic HPLC pump can be used
in conjunction with a PRP X-100 strong anion exchange column
(or equivalent) to separate up to four arsenic species; arsenite (AsIII),
dimethylarsenic acid (DMA), monomethyl arsonic acid (MMA) and arsenate (AsV). For
the determination of non-reducible arsenic species such as arsenobetaine (AsB),
arsenocholine and Trimethylarsine oxide ((TMAO) and arsenosugars; a PSA 10.570 UV oxidation system can be included.
This approach can be used for arsenic speciation in drinks, urine or any matrix after suitable extraction.
Detection limits in the region of 0.2ng ml-1 are readily achievable. With excellent l.o.ds, reproducibility, and ease-of-use arsenic speciation has never been so easy.
The system consists of a 1100 series Isocratic pump, manual injection valve and solvent cabinet. With the simple addition of the correct column, the analyser and hand held are ready to run.
The 1100 series pump is made of robust materials to withstand the most demanding of applications; stainless steel, titanium, gold, ruby, sapphire, ceramics, PEEK and PTFE. The seal wash option for high salt mobile phases keeps maintenance to a minimum, thereby providing lower operational costs.
The system can be enhanced by the C723I009 ChemStation base software. This software is the industries' most widely sold data system, handling all applications including LC, LC/MS, GC, CE and CE/MS. This base provides the ideal platform for labs that need an easy-to-learn and easy-to-use system, which can be scaled up and extended as the laboratory's needs grow.
