Binders for paints and varnishes. Gum rosin. Gas-chromatographic analysis Ingestion-build-61878 The introduction of a deflectometer1 Scope This International Standard specifies a gas chromatographic method for determining the amounts of certain rosin acids in gum rosin using capillary gas chromatographic separation of the volatile methyl esters of these acids. It is intended primarily to permit the identification of gum rosin from specific species of pine trees. It is not designed for the quantitative analysis of gum rosin. If such analyses are required, the internal standard
