Brief Method Summary

I. Sample volume and initial sample treatment: See Standard Methods section 3030 for sample pre-treatment and digestion. II. Determinative step: ICP/MS. Follow manufacturer's instructions. III. Cleanup: No procedures given.

Scope and Application

Applicable Concentration Range

0 - 100ug/L. Acceptable limits may be changed to bracket sample concentration as long as linearity is proven.

Interferences

Other elements or substances can interfere at the m/z's of the elements of interest and high solids can clog the nebulizer.

Quality Control Requirements

Not Included

Sample Handling

Sample container, preservation, and storage: See Standard Methods section 3010-B for sampling and sample preservation.

Maximum Holding Time

Relative Cost

$201 to $400

Precision Descriptor Notes:	Precision and accuracy were determined using single laboratory analyses of 20 replicates of natural waters spiked with analytes of interest. Analyses were preceded by Standard Method 3030 E (modified by clean-hood digestion in TFE beakers). Information on monitoring masses used is provided in the method.
