Defines a method for determining trace amounts of Molex desorbent (n-pentane, isooctane, p-xylene) in C[10]-C[18] Molex products.

Molex is an adsorptive separation process that separates normal paraffins from branched chain and cyclic hydrocarbons.

This method is for determining trace amounts of Molex desorbent (n-pentane, isooctane, p-xylene) in C10-C18 Molex products. The lower limit of detection for n-pentane and isooctane is 5 mass-ppm. Early eluting Molex product may cause interference at the p-xylene site. Therefore, the lower limit of detection for p-xylene can be as high as 50 mass-ppm.
