Determination of 1,2,4-trimethylbenzene (pseudocumene) in serum of a person exposed to liquid scintillation counting solutions by GC/MS.
1,2,4-Trimethylbenzene (pseudocumene) is often used as the solvent for liquid scintillation counting solutions. In the present work, the determination of 1,2,4-trimethylbenzene in the serum of a person exposed to the solvent vapor during the handling of liquid scintillation counting cocktails is described. The identification of 1,2,4-trimethylbenzene was carried out by GC/MS. The analyte was quantified by GC with flame ionization detection. The detection limit of the method is 0.01 ppm. Two hours after exposure of a person to the solvent vapor, the concentration of 1,2,4-trimethylbenzene in her serum was found to be 0.20 ppm.
