Page 2 of 3 <br /> Our lab indicated that they do not have the capability to analyze antimony and thallium using the analytical <br /> methods referenced in Table 2. These methods appear to be graphite furnace methods and our lab indicated <br /> that they are unsure if anyone still has the capability to perform these analysis and are unaware of a lab that <br /> does. Consequently, will it be okay to use the 6000 series analytical method for these two constituents. <br /> Thank You, <br /> Larry J.

Or he can call me directly to discuss it <br /> Also, detection limits need to be sufficiently low for comparison to the SWRCB Water Quality Objectives. He can <br /> check them online at <br /> http://www.waterboards.ca-gov/water issues/programs/water quality goals/search shtml. <br /> Thanks. <br /> Jim Barton <br /> James L. L. Barton P.
