1 Scope
1.1 General
This Standard describes a method for the quantification of the aliphatic (R–OH), carboxylic acid (R–COOH), and phenolic (Ph–OH) hydroxyl groups present in lignin. Phenolic hydroxyl groups include
a)
syringyl (S), guaiacyl (G), and p-hydroxyphenyl (H) units; and
b)
condensed phenolics incorporating ß-5, 4-O-5’, and 5-5’ inter-unit linkages.

Methods of testing petroleum and associated products Standard test method for the identification of ...
This test method is a standard procedure for the determination of paraffins, olefins, naphthenes, aromatics
and unknowns (P.O.N.A.U.) in automotive gasolines using gas chromatography and flame ionization detection
(GC/FID). Individual hydrocarbon components greater than or equal to 0.01 % by mass are determined. Group types
greater than or equal to 0.01 % by mass are determined by summing…
