Pulp, paper and board. Determination of primary aromatic amines (PAA) in a water extract by a LC-MS method Ingestion-build-47786 such that they play aWhat is this standard about? This document describes two representative methods for the determination of the extractable amount of specific primary aromatic amines (PAA) in a water extract of paper, board and pulp samples by means of HPLC with MS MS detection which basically differ concerning the choice of the mobile and stationary phases. Deviating from this standard further methods may be applicable if it can be shown that comparable results can be
