1 Method Summary
Weighted samples are put into crucible for destructive distillation. Cracking and pyrogenic reaction of residue is carried out after strong heating for certain time. After heating for certain time is finished, the crucible with carbon residue is put into the dryer for cooling and weighed; the carbon residue value is calculated (express by mass percent of original sample).
