  • Method for isotopic analysis of water in bodily fluids
    Patent number: 9110008
    Abstract: Biological fluid samples containing proteins (e.g., blood plasma or saliva) are prepared for isotopic analysis by precipitating the proteins while leaving the isotopic ratio unaffected. This precipitation can involve adding metal ions, salts, organic solvents, or organic polymers. The sample is then centrifuged to allow transfer of the supernatant for isotopic analysis, e.g. by tunable diode laser absorption spectrometry to obtain a quantitative measure of the 2H and 18O isotope levels in the water relative to reference standards.
    Type: Grant
    Filed: July 26, 2011
    Date of Patent: August 18, 2015
    Assignee: Los Gatos Research
    Inventors: Douglas Steven Baer, Elena Simone Franklin Berman, Manish Gupta, David A. Wagner, Daniel L. Bolt, Susan Lauren Fortson
