Standard Practice for Electrothermal (Graphite Furnace) Atomic Absorption Analysis
This practice is intended for spectroscopists who are attempting to establish electrothermal atomic absorption procedures. Used in conjunction with Practice E 663, it should be helpful for establishing a complete atomic absorption analysis program.
1.1 This practice covers a procedure for the determination of microgram per milliliter (μg/mL) or lower concentrations of elements in solution using an electrothermal atomization device attached to an atomic absorption spectrophotometer. A general description of the equipment is provided. Recommendations are made for preparing the instrument for measurements, establishing optimum temperature conditions and other criteria which should result in determining a useful calibration concentration range, and measuring and calculating the test solution analyte concentration.
1.2 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific safety hazard statements are given in Section 9.
