Infrared quantitative analysis of the amount of crosslinker or hardening agent in a photoconductor overcoat bath is possible by the preparation steps of removing the bath solvent through evaporation and redissolving the solid residue into an infrared (IR) analysis compatible solvent. In the example discussed in detail below, the xylene solvent is incompatible with infrared spectroscopy in that it obscures the crosslinker IR band. The xylene solvent is removed by evaporation, and the solid residue is then dissolved in a chloroform solvent which is compatible with the IR spectroscopy procedure.
