Description
Technical Field
The utility model relates to an automatic quantitative sampling device of tobacco powder specifically is an automatic quantitative sampling device of carousel type gravity flow powder.
Background
In conventional analytical testing, large batches of test samples are often required. The repeated weighing of samples occupies a large amount of working time of detection personnel, and in the face of the automatic sample introduction detection function of a modern analysis instrument after sample processing, repeated weighing of a large number of samples is a bottleneck problem of high-throughput detection. For example: in the analysis and detection of conventional components (such as nicotine content) of tobacco, if a large batch of samples are detected, the tobacco samples are repeatedly weighed no matter what standard method (YC/T383-. Tobacco samples are prepared according to YC/T31-1996 tobacco and tobacco product sample preparation and moisture determination oven method, namely tobacco powder which is dried at 40 ℃, ground and sieved is weighed, if 30 seconds are needed for weighing one sample, 60 samples are weighed, and the work is time-consuming and labor-consuming for testers.
In addition to repeated weighing of samples, in many sample pre-treatments, some materials required for pre-treatments need to be weighed repeatedly. Because many gas chromatographic columns are fixed to water intolerance, a certain amount of drying agent (usually powdery anhydrous sodium sulfate) needs to be weighed into a sample before gas chromatographic analysis sample introduction, so as to adsorb moisture in a sample to be detected, and for a large batch of detection samples, anhydrous sodium sulfate needs to be repeatedly weighed for many times. For example: YC/T288-2009 gas chromatography for determination of polybasic acids (oxalic acid, malic acid and citric acid) of tobacco and tobacco products stipulates that 3.5g of anhydrous sodium sulfate needs to be added into the extract liquid for drying overnight before gas chromatography analysis; YC/T383-2010 (gas chromatography-mass spectrometry) regulations on the determination of nicotine, nornicotine, neonicotine, mesminne and anabasine require that part of extract liquid passes through an anhydrous sodium sulfate small column in sample pretreatment, wherein the anhydrous sodium sulfate small column is prepared by adding 4g of anhydrous sodium sulfate into a disposable sterile syringe.
In summary, when a large amount of samples are tested, a lot of time and effort are consumed by testing personnel due to repeated weighing of the samples and materials that may be needed in the pretreatment, and an automatic quantitative sampling device is needed to replace manual repeated weighing.
