Organization: ASTM
Publication Date: 25 May 1990

Page Count: 4
scope:

1. Scope

1.1 This test method covers the determination of the resin acids in tall oil, gum, or wood rosin after conversion to their methyl esters.

1.2 The composition is calculated from the ratio of each peak area to the total area of all peaks obtained. Rosins generally contain nonvolatile or polymeric materials for which no peaks are obtained under the conditions used. On the other hand, volatile neutral materials elute in the general region of resin acid methyl esters and can result in errors in the calculated composition. More reliable data is obtained by removal of neutral materials before gas chromatography.

1.3 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards are given in Note 2.
