  • DETECTION OF A COMPONENT OF INTEREST WITH AN ULTRAVIOLET LASER AND METHOD OF USING THE SAME
    Publication number: 20120135537
    Abstract: Means and method for analysis of a component of interest in a sample is provided. A small sample cell is provided which decreased dispersion of the sample. Also provided is a device for detection of a component of interest in a sample in which the small sample cell is used with an ultra violet laser in which the energy of the laser is spread over an area such that energy density is above desorption threshold, but the sample not ablated. Rapid and reliable detection of a component of interest is provided with the invention.

  • ORAL FLUID ASSAYS FOR THE DETECTION OF HEAVY METAL EXPOSURE
    Publication number: 20100291693
    Abstract: Methods for measuring the concentration of heavy metals such as aluminum, antimony, arsenic, barium, beryllium, cadmium, chromium, cobalt, copper, lead, manganese, molybdenum, nickel, selenium, silver, strontium, thallium, uranium, vanadium, zinc, or mixtures thereof in oral fluid are provided. The concentration of heavy metals in oral fluid can be accurately correlated with the concentration of heavy metal in the blood serum. The methods are useful for, among other things, diagnosis and monitoring of heavy metal exposure.

  • METHOD AND APPARATUS TO DETECT CHEMICAL VAPORS
    Publication number: 20080296491
    Abstract: Means and method of rapid detection of a compound of interest from an air sample is shown. An air sample is collected, and concentration of the compound of interest can be increased. A portable spectrometer, which preferably is a time-of-flight spectrometer, detects the presence of any of the compound. The system allows for rapid detection of the presence of a compound in an air sample in a field setting.

  • 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.
