| titleOfInvention | A method for the determination of total sulfur dioxide in tobacco or tobacco products by continuous flow method |
| abstract | The invention relates to the technical field of tobacco, in particular to a method for determining total sulfur dioxide in tobacco or tobacco products by a continuous flow method. The detection method of the present invention is to react the distillate of tobacco or tobacco products, formaldehyde and basic fuchsin to form a complex, measure the absorbance of the complex at 550 nm, and calculate the tobacco or tobacco product through a predetermined standard curve. The concentration of total sulfur dioxide in the extraction filtrate. The assay method of the invention can improve the accuracy of detecting the concentration of total sulfur dioxide in tobacco or tobacco products, improve the detection efficiency and reduce the assay cost. |
