||The Health and Safety Executive interlaboratory quality control scheme for isocyanates
||Feb. 1990, Vol.34, No.1, p.77-83. 9 ref. Illus.
||The AQUA (Analytical Quality Assurance) isocyanate scheme is linked to a specific analytical method, MDHS 25 (Organic isocyanates in air: laboratory method using 1-(2-methoxyphenyl) piperazine solution and high performance liquid chromatograph, see CIS 84-1618). Results from the first 4 years of the scheme's operation are reviewed and individual laboratory performance indices assessed against the mean interlaboratory performance indices. Most of the laboratories in the scheme show a marked improvement with time, which in some instances has followed help and advice form the HSE. There has also been an overall reduction of interlaboratory variability over this period.
