The transfer of sample, the stability and consistency of operation are by large effect.
Therefore how in the case where sample pre-treatments are normally carried out, shorten operation link and step as far as possible, it is ensured that efficiently,
It is rapidly completed that the demand of the laboratory apparatus of sample pre-treatments is urgent and high throughput analysis and batch samples handle
Important leverage.
Utility model content
The utility model provides a kind of sample injection bottle of carry sample pretreatment function, efficiently solves sample pre-treatments step
It is complicated, link is more, operational stability difference problem.
A kind of sample injection bottle of carry sample pretreatment function, including body 1 and bottle cap 3, accommodating in body 1 can be along body 1
The pushing casing 2 of axial movement pushes the one end mutually close with the bottom of bottle of body 1 of casing 2 and is equipped at intervals with the first filter membrane 4 and the
Two filter membranes 6 push casing 2 far from one end of bottom of bottle and are equipped with bottle cap 3, and bottle cap 3 is threadedly coupled with body 1.
In the utility model preferred embodiment, filler, filler are placed on the first filter membrane 4 and the second filter membrane 6
For one of desiccant particle, carbon adsorption particle or silica gel particle or a variety of.
In the utility model preferred embodiment, the aperture of the first filter membrane 4 and the second filter membrane 6 is 0.45 μm.
In the utility model preferred embodiment, rubber pad 5 is equipped in bottle cap 3, rubber pad 5 is salable to be open,
Depending on sample introduction demand.
In the utility model preferred embodiment, the opening diameter of body 1 is 9mm, and bottom of bottle diameter is 12mm, body 1
Volume be 2mL, body with scale in order to solvent volume confirmation.
The course of work of the utility model is placed in body 1 after weighing sample to be tested, and adds Extraction solvent, so
Afterwards according to sample pre-treatments demand, filler is placed on the first filter membrane 4 and/or the second filter membrane 6, and (filler is desiccant
One of grain, carbon adsorption particle or silica gel particle are a variety of), then extracted in the way of ultrasound, oscillation or heating etc.
Processing after extraction, opens bottle cap 3, will push casing 2 and is pressed into body 2, so that the first filter membrane 4 and/or the second filtering
Film 6 is immersed in the Extraction solvent of body 2, to be filtered and shift to test sample, to complete mentioning for test sample
Sample to be tested can finally be placed directly into analysis instrument and carry out by the integrated operation processing for taking, dry, filtering and shifting
It tests and analyzes.
The utility model has the advantages that
(1) the utility model pushes casing by being arranged in sample bottle, and filter screen is arranged on pushing casing, can be same
Shi Shixian treats the extraction, filtering, transfer of test sample in sample bottle, while filler can also be placed on filter membrane, real
Now to sample pre-treatments such as the drying of sample, impurity absorptions.
(2) the utility model integrates multiple pretreatment process such as sample extraction, filtering, drying, absorption, no longer needs to pair
Sample carries out solution transfer, container replacement, can directly be tested after sample treatment, the intersection of multiple containers is avoided to make
With greatly simplifying sample pre-treatments step, simplify pre-treating method.
(3) utility model device is simple and convenient, testing cost is effectively reduced, at the same ensure the stability of experiment with it is parallel
Property, substantially reduce and think to operate brought error, for analysis detection high throughput analysis provide equipment support and necessary guarantee.
