Special Issues
Low-level analysis of food matrices has placed a demand on manufacturers, testing laboratories, and instrumentation vendors worldwide. Stricter regulations, better analytical instrumentation, and greatly improved sample preparation (preanalytical) techniques have focused efforts to simplify and standardize these analyses.

The California Department of Public Health has proposed to establish the first regulatory limit in the United States for hexavalent chromium (chromium-6) in drinking water. The proposed Maximum Contaminant Level (MCL) sets the limit for hexavalent chromium at 10 parts per billion. California, like those of other states and United States federal government, currently only regulates total chromium levels.

Conventional pneumatic nebulizer-spray chamber combinations for ICP spectrometry have a sample introduction efficiency of only 1-3%. A unique electrothermal vaporization device developed by Vassili Karanassios of the University of Waterloo uses field-portable rhenium filament coils with a very small vaporization chamber and increases the sample introduction efficiency to 100%.
