Brief Method
Summary:

A 100-mL sample is processed through an ion exchange (IE) column to prepare it for analysis. The concentrations of uranium isotopes in the prepared sample are then determined using an inductively coupled plasma-mass spectrometry (ICP-MS) system.

Scope And
Application:

This method determines uranium and the isotopic ratio of uranium in groundwater and drinking water. The information provided by this procedure will allow for evaluation and determination of U-235 enrichment or depletion.

Applicable
Conc Range:

0.01ug/mL - * (* Method does not specify an upper detection limit.)

Interferences:

(A) Isobaric Interferences: Isobaric interferences may occur due to presence of Pu, Pa, and Np.
(B) Mass Loading: Interferences due to high mass loading are observed in presence of Zn and Fe and some other elements.

QC Requirements:

instrument and prep check std. solns., MS with known concentration, IA of U, spiked with 233U

Sample Handling:

Implement the processes specified in Method 6020 CLP-M Version 8.0 whenever applicable. Collect the sample with special care, and place all the samples in a sealed container. Provide proper shielding to handle the sample safely.

Max Holding Time:

Relative Cost:

$51 to $200
