Description
Technical field
The utility model relates to a kind of extraction equipment, particularly relates to a kind of meat volatile flavor substance headspace solid-phase microextraction device.
Background technology
The volatile flavor substance of meat is the key factor affecting raw meat and various meat packing product, and its component, kind and content are one of important composition factors of meat and its products flavor quality, is also the important indicator of its organoleptic quality evaluations.
After the volatile flavor substance of meat often adopts extraction, binding analysis instrument carries out analysis and resolution again.Solid-phase Microextraction (Solid Phase Micro-extraction, SPME) analyze pre-treating method as a kind of novel non-solvent volatile flavor substance, its selective extraction characteristic overcomes the shortcomings such as the pre-treatment sample requirements such as traditional vapor distillation method, solvent extraction, supercritical fluid extraction are large, length consuming time; Be convenient to realize robotization and be easy to efficiently be separated detection means coupling with chromatogram, electrophoresis, liquid phase, gas chromatography-mass spectrum (GC-MS) etc., and be applicable to the pretreatment technology of gas, liquid and solid sample analysis.At present, the mensuration of meat and meat product volatile flavor substance thereof often adopts solid-phase microextraction technology, and this technology has been widely used in food aroma component analysis.
When adopting headspace solid-phase microextraction to measure meat volatile flavor substance in conjunction with low-polarity components, heat to extract volatile flavor substance on thermostat water bath.But Problems existing is ml headspace bottle lighter weight, although after adding sample, also still water-bath can not be placed in vertical state.Extraction flask swings back and forth in water-bath, very easily damages being attached thereto the expensive extracting head connect, and can affect effect and the quality of extraction.
When meat volatile flavor substance extracts, usually select 60-90 DEG C.As directly used water-bath, the water vapor be evaporated can be condensed into the globule on extracting head handle and extracting head, more can affect the serviceable life of extracting head and handle.Because the evaporation of this temperature range water vapor is very fast, often can occur because not adding water in time, and cause the water in water-bath not have sample in extraction flask completely, finally not obtain good effect of extracting.
Utility model content
The purpose of this utility model is just to provide a kind of meat volatile flavor substance headspace solid-phase microextraction device, can solve above-mentioned the deficiencies in the prior art part completely.
The purpose of this utility model is realized by following technical proposals:
A kind of meat volatile flavor substance headspace solid-phase microextraction device, comprise thermostat water bath and pot top cover, thermostat water bath is provided with the temperature control panel controlling water temperature in pot, it is characterized in that: described thermostat water bath inner bottom part is provided with fixed cover, and on pot top cover, correspondence offers through hole.
Further, described thermostat water bath is provided with timing alarm apparatus.
Further, described through hole is provided with sealing-plug.
Further, described thermostat water bath is provided with osculum and filler pipe, filler pipe one end is communicated with in thermostat water bath, and the other end connects water source.
Further, float is provided with in described thermostat water bath.
Further, described pot top cover and fixed cover all adopt elastomeric material to make.
Compared with prior art, the beneficial effects of the utility model are: structure is simple, reasonable in design, can not only effective fixed extractor bottle, be convenient to extraction flask and extracting head simultaneously and extract handle and tighten together, extraction flask is made to keep vertical state when extracting, and can prevent water vapor evaporation from causing damage to extracting head handle and extracting head, the volatile flavor substance of abundant, complete extraction sample, is more conducive to testing easily.
Accompanying drawing explanation
Fig. 1 is front elevation of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is the vertical view after removing pot top cover;
Fig. 4 is using state figure of the present utility model.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in Figures 1 to 4, a kind of meat volatile flavor substance headspace solid-phase microextraction device, comprise thermostat water bath 1 and pot top cover 2, thermostat water bath 1 front is provided with the temperature control panel 4 of water temperature in timing alarm apparatus 3 and control pot, described thermostat water bath 1 inner bottom part is provided with fixed cover 5, on pot top cover 2, correspondence offers through hole 6, and described through hole 6 is provided with sealing-plug 7.
Described thermostat water bath 1 side bottom is provided with osculum 9, and filler pipe 10 is installed in side, and filler pipe 10 one end is communicated with in thermostat water bath 1, and the other end connects water source.Float 11 is also provided with in described thermostat water bath 1.
Described pot top cover 2 and fixed cover 5 all adopt elastomeric material to make.For the ease of picking and placeing pot top cover 2, pot top cover 2 is symmetrical arranged a pair handle 14.
See Fig. 4, when carrying out extraction work, choose highly suitable extraction flask 12, the height of extraction flask 12 is higher than thermostat water bath 1 internal height 1cm, and when preventing thermostat water bath 1 topped up with water, the water surface exceedes extraction flask 12 bottleneck and causes sample contamination.Then, extraction flask 12 is vertically put into thermostat water bath 1, extraction flask 12 bottom is inserted in fixed cover 5 and is fixed, top is inserted in the through hole 6 on pot top cover 2 and extraction bottleneck is in through hole 6, bottleneck external diameter and the through hole 6 of extraction flask 12 match, extracting head 13 is arranged on extraction flask bottleneck, extracting head 13 has extracting head handle 8, therefore effectively can avoid the damage that water recovery causes extracting head 13 and extracting head handle 8.And extraction flask head 13 not only coordinates with extraction flask 12, also coordinate with through hole 6 simultaneously, therefore can well make it keep vertical state by firm extraction flask 12.
It is to be particularly noted that a through hole 6 in use must be stayed not insert extraction flask 12, be convenient to water vapor and overflow, avoid build-up of pressure excessive, the phenomenon that pot top cover 2 flicks.
Utilize temperature control panel 4 to adjust, the water temperature controlled in thermostat water bath 1, utilize timing alarm apparatus 3 to record the heated sample time, heating duration reach setting-up time after give the alarm remind experimenter take out sample, carry out next step operation.
When the water in thermostat water bath 1 scatters and disappears too much, can automatically pass through filler pipe 10 to moisturizing in thermostat water bath 1, utilize water surface elevation automatically to control amount of water by float 11.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
