  • Flameless atomic absorption spectrophotometer
    Patent number: 5424832
    Abstract: A flameless atomic absorption spectrophotometer including a valve controller that connects the inside of the heating tube to the inert gas source before the sample is atomized, whereby water vapor or organic vapor generated from the sample before the atomizing stage is expelled from the tube through the sampling hole. In the atomizing stage of the heating program, the valve controller connects the inside of the heating tube to the outer atmosphere, whereby the atomized sample can expand along the optical path within the heating tube.
