Welcome to the October issue of EVISA's Speciation Newsletter !
This month newsletter is devoted to arsenic speciation analysis. Arsenic is one of WHO’s 10 chemicals of major public health concern. Human exposure to arsenic is mainly via drinking water and food, calling for effective analysis and control. Arsenic toxicity is heavily dependent on the species present, making total arsenic determination not informative enough for meaningful risk assessment. Unfortunately, most element selective detection techniques are not species selective and therefore require to be combined with a separation technique. The required separation of species prior to their detection is reducing the sample throughput of the analysis considerably, making it more costlier. For this reason, optimization of the separation with respect to resolution and analysis time is a major issue for method development. Now, researchers from Italy propose to use frontal chromatography for fast separation of inorganic arsenic species. The principle advantage of the technique is the simple instrumental setup providing high sample throughput (see the news below).
Obtaining accurate quantification in speciation analysis is another issue for method development. External calibration requires appropriate standards. When plasma conditions change during the analysis time due to matrix coeluting with species, external calibration calls for standards for each species or an effective internal standard. The most effective procedure for internal standardization for speciation analysis is post-column isotope dilution, which unfortunately cannot be applied for arsenic because it is mono-isotopic. Now researchers from Czech Republic propose selenium as an internal standard for arsenic determination (see the news below).
