## Abstract Traditionally‐suggested combustion time of 1 h at 550°C) with the sealed‐tube combustion method for determining the ^13^C/ ^12^C ratio of cellulose nitrate or other nitrogen‐containing components could produce large negative deviation up to 1°. Three types of cellulose are used to ascer
