Selenium at low levels is an essential human nutrient, but at higher levels, human exposure to selenium can cause both short and long term health effects. Short term effects include changes to hair and finger nails, damage to the peripheral nervous system, and increased fatigue and irritability. Long term exposure to selenium has been linked to loss of hair and fingernails, damage to kidney and liver tissues, and damage to the nervous and circulatory systems.
The analytical performance of the system meets the
performance criteria set out in the Method, and the
comprehensive QC Tests facilities provided in the
SOLAAR software permit the detailed Quality Control
requirements of the Method to be quickly and simply set
up. The flexible Calibration functions, together with
Furnace Autosampler facilities, allow the Method of
Standard Additions calibration strategy to be easily
implemented if necessary.
