Abstract: This article presents a comparison of the extractability of As and Sb species from biological matrices as well as two different detection principles that have been coupled on-line with HPLC separation of As and Sb species for the purpose of determining speciation patterns in specimens arising from environmental and human biomonitoring.

Abstract: Electrography, first developed by Glazuaov and Fritz,1 is an analytical method used to identify and determine solid substances. It has been used for more than 60 years and was frequently used in the 1950s. However, with the development of modern analysis techniques such as laser technology, electron fault detection, and atomic absorption spectrophotometry, electrography is now rarely used because it depends on the color that develops directly on the filter paper after the ions have been transferred onto it. This method is used mainly for qualitative analysis rather than exact quantitative analysis. Particularly in multicomponent specimens, the large number of interferents always have an effect on the exact quantity of the trace components. Therefore, use of electrography has been severely limited up to now.
