Brief Method
Summary:

The sample is prepared using an appropriate metals digestion procedure, and the digestate is analyzed uing a graphite furnace atomic absorption (GFAA) spectrometer to quantitate metals in the sample.

Scope And
Application:

Electrothermal atomic absorption permits determination of most metallic elements in water with sensitivity and detection limits from 20 to 1000 times better than those of flame techniques.

Applicable
Conc Range:

Varies with analyte.

Interferences:

(1) Molecular absorption can occur when components of the sample matrix volatilize during atomization resulting in broadband absorption. (2) Chemical and matrix interferences can occur, but may be mitigated by using matrix modifiers.

QC Requirements:

See Standard Methods Section 3020.

Sample Handling:

See Method 3030-B for sample collection information.

Max Holding Time:

6 months

Relative Cost:

$201 to $400
