ISO 19334:2010 Binders for paints and varnishes – Gum rosin – Gas-chromatographic analysis

CDN $115.00

SKU: 580cbd328877 Categories: ,

Description

ISO 19334:2010 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 technique specified in ASTM D 5974 should be used.
