9.2.2 Semi-Volatile Organic Compounds - The results of two
studies are shown in Tables 7 and 8. Single laboratory
precision was excellent with greater than 90 percent of
the results exhibiting an RSD less than 25 percent. Over
85 percent of all individual compounds in the multilaboratory
study fell in the RSD range of 20 - 120
percent. Both studies concluded that the TCLP provides
adequate precision. It was also determined that the high
acetate content of the extraction fluid did not present
problems (i.e., column degradation of the gas
chromatograph) for the analytical conditions used.
