ABSTRACT:
Disclosed is an atomic absorbtion spectrophotometer method and apparatus, for automated real time analysis of an analyte in a continuous process stream. The apparatus comprises a sample arm for delivering a quantity of sample from a sample cup to a sample atomizer. The sample cup is in valved communication with each of a source of fluid sample and a source of wash solution. In a preferred embodiment, the sample cup is additionally in valved communication with a source of a reference control. Additionally disclosed is an easily serviceable sample atomizer, having a tungsten coil heating element removably secured therein.
