Abstract

A modification of a chemical preparation procedure for oxygen isotope analysis of cellulose has been developed which yields greater precision and requires less time for sample preparation. In the place of isoquinoline, zinc is used to remove HCl from the reaction products of the sample and HgCl2. The two methods give systematically different results because isoquinoline biases measurements by contaminating the sample with additional CO2. For the zinc method, precision is ±0.2%o (1σ standard deviation) compared with ±0.9%o for the isoquinoline method.
