A VCM standard in THF was prepared on 3/12/74 as per Method GCF-1.0. The theoretical values for the new standard were calculated to be 315 ppm and 32 ppm. The levels found when calculated against a previously-prepared standard were 332 ppm and 31 ppm respectively.
We are ready to perform an interlaboratory round robin.
