title: Determination of 2-methyl-4-chlorophenoxy (MCPA) in urine using combined TLC and HPLC methods.
abstract: Determination of MCPA, (2-methyl-4-chlorophenoxy) acetic acid, in urine has been improved by a preliminary TLC cleanup followed by HPLC with fluorescence detection. This procedure is suitable for routine analysis and has been applied with good results to an epidemiological investigation. Time required for each determination may be somewhat longer, but the proposed cleanup technique increases the specificity.
