Determination of uranium in environmental samples using inductively coupled plasma mass spectrometry

An analytical technique using inductively coupled plasma mass spectrometry has been developed to estimate the concentration of uranium in a variety of environmental samples. The lower limit for quantitation is 0.1 ng/mL. Calibration is linear from the low limit to 1000 ng/mL. Precision, accuracy, and a quality control protocol have been established. A comparison with the conventional fluorometric method has been performed.
