Measurement control program 092: Mercury in urine: Artificial urine versus natural urine external control solutions

摘要

An investigation was conducted to determine if any significant differences exist between the use of artificial urine vs. natural urine in the preparation of external control samples for Measurement Control Program Number 092, Mercury in Urine. Artificial urine is routinely prepared for use in Measurement Control Program Number 091, Uranium in Artificial Urine. A suggestion has been made that this same solution can be used for the mercury in urine program. Through the use of artificial urine, the need for the collection of a mercury-free natural urine is eliminated. Special handling requirements associated with natural urine are also avoided.
