This method is an analogue to AWPA Method A18,
however, use of chloroform as a titration reagent has been
eliminated and visual determination of a color endpoint has
been replaced with a potentiometric endpoint using an
automatic titrator. This method can be used to determine
concentrations of quaternary ammonium compounds (quats)
in wood. It is intended for routine quality control in wood
treating and is not suitable for trace levels of quats in wood.
