| titleOfInvention | Simultaneous Determination reconstituted tobacco oxalate, amber acid radical, the sample-pretreating method of sulfate radical and phosphate radical |
| abstract | The invention discloses the sample-pretreating method of a kind of Simultaneous Determination reconstituted tobacco mesoxalic acid, butanedioic acid, sulfuric acid and phosphate radical.The present invention be by reconstituted tobacco sample using pyrovinic acid as extract oscillation extraction after again through membrane filtration, take gained filtrate i.e. prepare liquid.The present invention ensures that the extraction efficiency of each component to be measured in sample reaches 99.7 more than % using pyrovinic acid as extract solution, it is effectively ensured exactly while detects reconstituted tobacco mesoxalic acid, the technical scheme of butanedioic acid, sulfuric acid and four kinds of components of phosphoric acid is realized, method is simple, reliable, at the same suitable for tobacco sample and reconstituted tobacco sample related component measure. |
