EPA Method 204.2:
Antimony by Graphite Furnace AA. Official Name: Antimony (Atomic Absorption, Furnace Technique)

A sample prepared according to EPA Method 200.0 is analyzed using a graphite furnace atomic absorption spectrometer. Specifications for instrument operation and preparation of standards are provided in the method.

This method determines antimony by graphite furnace atomic absorption spectrometry. Sample pretreatment according to EPA Method 200.0 determines the applicability.

Methods for the Chemical Analysis of Water and Wastes (MCAWW) (EPA/600/4-79/020)

Chloride: Interferences from chloride are prevented by adding an excess of 5 mg of ammonium nitrate to the furnace and ashing (using a ramp or steps) until the ashing temperature is reached.For additional interferences see EPA Method 200.0.

QC Requirements:
QC requirements for drinking water procedures are provided in method 200.0.

Maximum Holding Time:
6 months (MCAWW, Table 1).



20-300 ug/L (optimal range).

Sample Prep:
