Brief Method 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 and Application
|
This method determines tin by graphite furnace atomic absorption spectrometry. Sample pretreatment according to EPA Method 200.0 determines the applicability. |
Applicable Concentration Range
|
20-300 ug/L (optimal range). |
Interferences
|
Background correction is recommended. Chloride: If chloride concentration presents a matrix problem or causes a loss previous to atomization, add an excess of 5 mg of ammonium nitrate to the furnace and ash until the recommended ashing temperature is reached. Extended ashing times have been reported to improve precision. For additional interferences see EPA Method 200.0. |
