Paints and varnishes
Identification of gum rosin gas chromatography
1 Scope
This standard specifies the use of capillary column to determine the volatility of the methyl ester of rosin acids in gum rosin rosin acid content of certain gas chromatography
Spectral Method. The main purpose is to identify specific types of pine rosin, but not for the quantitative analysis of gum rosin. If you need to
Quantitative analysis should be specified in accordance with ASTMD5974 internal standard method was measured.
