Abstract
Thermogravimetric analysis was applied to the rapid determination of moisture in tobacco and tobacco products.The temperature programming (the temperature rose to 110 ℃ at the rate of 50 ℃·min-1 ,then keep 8 min) was used.The proposed method was applied to the analysis of samples of tobacco powder and cut tobacco,giving results in consistency with the values obtained by oven method.Thermogravimetric method required only 10-20 mg of samples (far less than the oven method) and test of the method took about 10 min.
