Brief Method Summary
 A sample prepared according to EPA Method 200.0 is analyzed using a flame atomic absorption spectrometer. Specifications for instrument operation and preparation of standards are provided in the method.
Scope and Application
 This method determines titanium by flame atomic absorption spectrometry. Sample pretreatment according to EPA Method 200.0 determines the applicability.
Applicable Concentration Range
 5 - 100 mg/L (optimal range); 2.0 mg/L (sensitivity).
Interferences
 For interferences see EPA Method 200.0. A number of elements increase the sensitivity of titanium. To control this problem, potassium must be added to standards and samples alike.
Quality Control Requirements
 QC requirements for drinking water procedures are provided in method 200.0
Sample Handling
 Sample handling and preservation procedures are provided in EPA Method 200.0.
Maximum Holding Time
 6 months (MCAWW, Table 1).
Relative Cost
 Less than $50
