Abstract
A kind of solid phase microemulsion preconcentrate device suitable for fresh tobacco leaves volatile materials, it is characterised in that：Air cleaner, gas collecting room, gas entrapment groove and vacuum air pump including being sequentially communicated by seal pipe are constituted, activated carbon is filled with air cleaner and air inlet pipe is provided with, solid-phase micro-extracting device is provided with gas entrapment groove and in the gas entrapment groove filled with silica-gel desiccant, the gas collecting room is printing opacity, air-locked closed cavity.The utility model has easy to operate, and in the case where tobacco seedling growth is not destroyed, can at any time detect the volatile materials of fresh tobacco leaves can truly reflect the instantaneous detection tobacco leaf volatile materials of tobacco leaf physiological status.
Description
Technical field
The utility model belongs to Plant Metabolome research field, and in particular to a kind of suitable for the new of metabolism group research
The solid phase microemulsion preconcentrate device of fresh tobacco leaf volatile materials.
Background technology
Tobacco leaf is one of important research object of cigarette quality and metabolism group.The volatility produced in tobacco leaf growth course
Material is not only important fragrance matter source, and is played in the anti-environment stress of cigarette strain as a kind of chemical information and focus on
Want function.Therefore, setting up the tobacco leaf volatile materials extracting method for holding water seems most important.
At present, extraction tobacco leaf volatile materials is collected both at home and abroad has absorption column adsorption method, water extraction method, vapor to flow back
Method, solvent such as directly extract at various methods.These methods all destroy the tissue of tobacco leaf, organ even volatility to some extent
The chemical composition of material, and it is subject to different degrees of pollution and loss unavoidably in wash-out or extraction process.Accordingly, it is capable to no grind
A kind of convenient, fast, easy tobacco leaf volatile materials extracting and enriching device of system, causes the concern of applicant in this case.
The content of the invention
The purpose of this utility model is just directed to the deficiencies in the prior art, and a kind of convenient, fast, letter for providing
Easily, the solid phase extraction concentration device of the instantaneous detection tobacco leaf volatile materials of tobacco leaf physiological status can truly be reflected.
The purpose of this utility model is achieved through the following technical solutions：
A kind of solid phase microemulsion preconcentrate device suitable for fresh tobacco leaves volatile materials, including be sequentially communicated by seal pipe
Air cleaner, gas collecting room, gas entrapment groove and vacuum air pump are constituted, in air cleaner filled with activated carbon simultaneously
Air inlet pipe is provided with, solid-phase micro-extracting device is provided with gas entrapment groove and is done filled with silica gel in the gas entrapment groove
Drying prescription, the gas collecting room is printing opacity, air-locked closed cavity.
The gas collecting room is printing opacity, air-locked closed glass cavity.
Loading of the silica-gel desiccant in gas entrapment groove is the 2/3 of gas entrapment groove volume, solid-phase micro-extracting device
Extracting head be located at gas entrapment groove top vallecular cavity in.
The solid-phase micro-extracting device is the SPME devices with extracting fiber of Supelco companies of U.S. production.
When in use, air passes sequentially through air cleaner, gas collecting room to the utility model under the suction of vavuum pump
With gas entrapment groove.Wherein, equipped with except impurity elimination gas, the activated carbon of purify air in air cleaner；Collection room is printing opacity, impermeable
The glass chamber of gas；Silica-gel desiccant, and its top carrying equipped with the production of Supelco companies of the U.S. are housed in gas entrapment groove
The SPME devices of extracting fiber, the fiber can complete the full enrichment of fresh tobacco leaves volatile materials.
The utility model has the advantages that, easy to use, volatile materials that can be in fast enriching fresh tobacco leaves can be true
The instantaneous detection tobacco leaf volatile materials of real reflection tobacco leaf physiological status.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model solid phase microemulsion preconcentrate device.
Wherein：1 air cleaner, 2 gas collecting rooms, 3 gas entrapment grooves, 4 vacuum air pumps, 5 cigarette strains, the micro- extraction of 6 solid phases
Take device, 7 seal pipes.
Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1：A kind of solid phase microemulsion preconcentrate device suitable for fresh tobacco leaves volatile materials, including by seal pipe
7 air cleaners 1 being sequentially communicated, gas collecting room 2, gas entrapment groove 3 and vacuum air pump 4 are constituted, in air cleaner 1
In filled with activated carbon and air inlet pipe is provided with, solid-phase micro-extracting device 6 is provided with gas entrapment groove 3 and in the capture groove
In be filled with silica-gel desiccant, the gas collecting room 2 be printing opacity, air-locked closed glass cavity.
Loading of the silica-gel desiccant in gas entrapment groove is the 2/3 of gas entrapment groove volume, solid-phase micro-extracting device
Extracting head be located at gas entrapment groove top vallecular cavity in.
When specifically used, cigarette strain 5 is put into gas collecting room 2, can be evacuated to for the gas that gathered in room 2 by vacuum air pump 4
Capture groove 3, air sequentially passes through air cleaner 1, gas collecting room 2, and capture groove 3 is captured the solid phase micro-extracting head in groove
SPME is adsorbed and is enriched with, and during air cleaner 1 of the air described in, filler activated carbon can remove miscellaneous gas, purify air,
During by described gas entrapment groove 3, filler silica-gel desiccant can have to the moisture mixed in tobacco leaf volatile materials
Effect removal, after through Supelco companies of the U.S. produce the SPME devices with extracting fiber can complete fresh tobacco leaves volatility
The full enrichment of material.Whole device is connected by seal pipe, the volatile materials that will directly can be adsorbed on SPME after the completion of trapping
Carry out effectively desorption and GC-MS analyzes detection.
