  • Universal transfer apparatus and method to use same
    Patent number: 7221861
    Abstract: The present invention provides universal transfer apparatus and method to use this universal transfer apparatus. This invention further provides a method to obtain speciation data for organometals in a complex matrix, such as cigarette smoke. Our data demonstrate that gas chromatography linked to inductively coupled plasma mass spectrophotometer with the universal transfer apparatus provides metal speciation information for samples of tobacco smoke. The organometals include lead, tin, arsenic and cadmium.
