Abstract
The utility model belongs to the field of sample pretreatment and particularly relates to an automatic ultrasonic extraction device for chemical substances in total particulate matter of cigarette smoke. A filter disc or an adsorbent with captured cigarette smoke or the like is put in the ultrasonic extraction device, and a solvent is automatically added for extracting, and extract liquor is automatically extracted after the extraction treatment. The automatic ultrasonic extraction device provided by the utility model is used for realizing automatic extraction and improving the pretreatment efficiency.
Description
Technical field
The utility model belongs to the sample pre-treatments field, is specifically related to a kind of automatic ultrasonic extraction equipment for cigarette smoke TPM chemical substance.
Background technology
Contain thousands of kinds of chemical substances in the flue gas that the cigarette burning process produces, the chemical composition that has identified is above 4000 kinds, the existing material that tobacco aroma, jealous and physiological action are provided in these chemical compositions, the material that produces assorted gas, stimulation and bad smell is also arranged, also have trace health to be produced the material of harm.Cigarette smoke is dimerous by gaseous substance and granule phase substance matter.Wherein at room temperature can cambridge filter (filter disc that a kind of glass fibre is made, its can filtering diameter greater than the particulate of 0.2 μ m, filter efficiency can reach 99%) flue gas partly be called granule phase substance matter.Extraction for granule phase substance matter in the cigarette smoke mainly is extracting process at present.In various extracting process, the ultrasonic extraction method is the most frequently used a kind of method.All be to use the ultrasonic extraction method as extractions such as tar, nicotine, benzo [a] pyrene, tobacco-specific nitrosamine, phenolic compound in the flue gas granule phase substance.
Therefore, a kind of automatic ultrasonic extraction equipment for cigarette smoke TPM chemical substance of invention can improve the detection analysis efficiency.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, a kind of automatic ultrasonic extraction equipment for cigarette smoke TPM chemical substance.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of automatic ultrasonic extraction equipment for cigarette smoke TPM chemical substance, wherein:
Described ultrasonic extraction device comprises the Ultrasound Instrument that extraction flask is housed, and the solvent bottle that links to each other with extraction flask by the extractant pipe; Extraction flask is provided with ultrasonic back extract efferent duct.
When using device of the present invention, will capture the filter disc of cigarette smoke or adsorbent etc. earlier and put into the ultrasonic extraction device and add solvent automatically and extract, automatically extract exported after extraction is finished.
For the flow of liquid in each pipeline in the control device, the extractant pipe is provided with the extraction pump, and ultrasonic back extract efferent duct is provided with ultrasonic pump.Preferably, above-mentioned extraction pump, ultrasonic pump are the Electromagnetic Flow pump.
Preferably, the internal diameter of the bottleneck of extraction flask is 34～40 mm, and the arc sections internal diameter of extraction flask is 94～100mm, and the bottom internal diameter of extraction flask is 130～134 mm; The capacity of solvent bottle is 2.5～4 L; Be provided with the cylinder recessed portion in the extraction flask, extract can be exported fully after the convenience for ultrasonic extraction is finished.
Compared with prior art, the present invention has following beneficial effect:
Significantly increase and detection object at present tobacco business tobacco test sample amount are more and more, and the present invention improves the detection efficiency of flue gas analysis with the extraction procedure automation of chemical substance in the cigarette smoke TPM.
Description of drawings
Fig. 1: the structural representation of the embodiment of the invention 1 described automatic ultrasonic extraction equipment.
Reference numeral table: 1 solvent bottle; 2 extraction flasks; 3 Ultrasound Instrument; 4 extraction pumps; 5 ultrasonic pumps.
The specific embodiment
The structure of device:
A kind of automatic ultrasonic extraction equipment for cigarette smoke TPM chemical substance
Wherein: described ultrasonic extraction device comprises that it is 34 mm that extraction flask 2(internal diameter of the bottleneck is housed, the arc sections internal diameter of extraction flask 2 is 94 mm, the bottom internal diameter of extraction flask 2 is 130 mm, be provided with the cylinder recessed portion) Ultrasound Instrument 3, and can hold 4 L solvents by the solvent bottle 1(that the extractant pipe links to each other with extraction flask 2); Extraction flask 2 is provided with ultrasonic back extract efferent duct.
Embodiment 2
The device that uses embodiment 1 to make up, and in conjunction with the method for describing among the GBT 23228-2008, carry out the ultrasonic extraction of chemical substance in the cigarette smoke TPM.Concrete grammar is as follows:
The filter disc (adsorbent) (filter disc or adsorbent trap be the flue gas TPM) that has captured cigarette smoke is put into the extraction flask 2 of Ultrasound Instrument 3, extractant (carrene) places solvent bottle 1, by extraction pump 4(20 ml/s, flow can be regulated according to actual conditions) 100 mL extractants in the solvent bottle 1 are transported in the extraction flask 2 extract, the ultrasonic extraction time is 10 min, extract was automatically by the extract efferent duct output of ultrasonic back after extraction was finished, and the final extract that obtains of handling can carry out next step processing.
The extract that obtains by this device automatic ultrasonic carries out subsequent treatment simultaneously with the extract that ultrasonic extraction mode in the past obtains, and detected uniformity as a result is fine, and relative deviation meets the requirement of standard code in 10%.The N-nitroso anabasine, the 4-(N-methyl nitrosamino group that record by this device)-the 1-(3-pyridine radicals)-1-butanone, N-nitrosonornicotine and the N-nitroso anabasine rate of recovery are respectively 93.4%, 94.8%, 94.5% and 91.2%.
