Chlordane,accompanied by a mixture of penta-, <br /> hexa-,hepta-,and nonachlorinated compounds,is defined by a group of five chromatographic peaks. It is necessary to de termine <br /> the percentage of Chlordane and its isomers in the standards used. <br /> INTERFERENCES: None identified,an alternate column is 2 m x 2-mm ID glass packed with 3%QF-1 on 100/120 mesh Chrom <br /> Q. <br /> OTHER METHODS: This is NIOSH method S278 in a revised format.
