EPA Method 283.2:
Titanium by Graphite Furnace AA. Official Name: Titanium (Atomic Absorption, Furnace Technique)

Summary:
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.

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