Atomic Spectrometry Update: review of advances in the analysis of clinical and biological materials, foods and beverages

“…This latest Update adds to that from last year 1 and complements other reviews of analytical techniques in the series of Atomic Spectrometry Updates from the last year. [2][3][4][5][6] In a follow-up to previous reviews, Kleparit described developments in CE and microuidic devices used together with MS, as published between January 2010 and June 2012. 7 Particular attention was directed to improvements with interfacing via ICP, ESI and matrix-assisted desorption/ionisation.…”

“…Concentrations ranged from 0.58 to 5.0 mg kg À1 (total As) and from 0.03 to 3.2 mg kg À1 (iAs). The potential exposure to iAs from consumption of dietary supplements was evaluated and compared with the European Food Safety Authority recommendations 3 COOH, were leached by means of an automated extraction procedure using hot water at 100 C at a pressure of 1500 psi for 5 min in 4 extraction steps. Total As concentrations were determined by ICP-MS and those of As III and As V by HPLC-ICP-MS.…”

“…Standoff LIBS has been employed for the classication of trace residues as either hazardous (explosives, biological, etc) or non-hazardous and has been reviewed in previous review articles, for example last year's review. 1 LIBS is very suitable for this type of analysis due to the requirement for minimal or no sample preparation, the minimal sample amount required to generate a usable emission spectrum and the ability to generate a signal in standoff mode, in some cases from a distance of many meters. However, correct classication of the analyte is very substrate dependent and varies in difficulty depending on what is underneath the residue.…”
