摘要：

A technique is described for the accurate and reproducible (0.2 per mille) determination of stable oxygen isotope ratios from wood alpha-cellulose using an improved version of the mercuric chloride pyrolysis method. In this a macroreticular resin, Amberlyst A-21, is used as absorbent for hydrogen chloride. The case for use of quartz rather than borosilicate reaction vessels is presented.
