Abstract
A kind of microscale sampler suitable for using in glove box, including microscale sampler outer tube, microscale sampler outer tube top is latex water dropper, has inner tube in the inner lower of microscale sampler outer tube, the top of inner tube is inner tube outlet., which there are left and right ends in the junction of the latex water dropper and microscale sampler outer tube respectively, 2 " W " ripple muscle.
Description
Technical field
The invention belongs to elimination of nuclear facilities improvement and disposal of three wastes fields, and in particular to microsampling in a kind of glove box
Device.
Background technique
The retired high, medium and low setting-out product system of disposal of three wastes industry is complicated, and sample analysis need to be in glove box, draught cupboard, hot cell
Equal closed environments carry out, and it is accurate, quick that sampling process requires, and sampler requires small in size, acid and alkali-resistance, convenient for operation.It is existing
Pipette volume is larger, inconvenient in closed environment.Existing Autosampler not acid and alkali-resistance, after a period of use accurately
Degree substantially reduces, and can only scrap, and becomes secondary waste, and costly.For meet sampling process requirement, in conjunction with glove box,
Sample practical operation situation in draught cupboard has invented a kind of sample accurately, convenient for operation, the microscale sampler of economy and durability.
Summary of the invention
It is an object of the invention to: microscale sampler in a kind of glove box is designed, solves existing pipettor in glove box, logical
Sampling operation is difficult in the closed environments such as wind cupboard, hot cell, and slowly, solving automatic pipettor, acid and alkali-resistance, accuracy be not unstable, consumption
Damage the more problem of big, secondary waste.
Technical scheme is as follows: a kind of microscale sampler suitable for using in glove box, including microsampling
Device outer tube, microscale sampler outer tube top is latex water dropper, has inner tube, the top of inner tube in the inner lower of microscale sampler outer tube
Portion is inner tube outlet.
, which there are left and right ends in the junction of the latex water dropper and microscale sampler outer tube respectively, 2 " W " ripple muscle.
Remarkable result of the invention is:
(1) pipette sampling accuracy rate is higher, but since its longer dimension is not available in glove box；And microsampling
Device compact is convenient for glove box use, and it is high to sample accuracy rate.
(2) Autosampler material is plastics, not strong alkali-acid resistance, and sample generally is strong acid system, automatic sampling
Device is lower through its sampling accuracy rate of acid corrosion, while service wear amount is larger in glove box,；And microscale sampler material is glass
Glass, have stronger acid-resistant corrosion, sampling accuracy rate it is higher, as long as and do not damage, can use always, service life compared with
Long, the purchasing price of an Autosampler is 2000 yuan, and the cost price of a microscale sampler is 200 yuan, is saved significantly
Master Cost is saved.
The utility model patent is small in size, easily operated, economy and durability, accuracy are high, is suitable for glove box, draught cupboard etc.
Quantifying for micro-example pipettes during radioactive sample analysis in closed environment.
Detailed description of the invention
Fig. 1 is microscale sampler schematic diagram in glove box of the present invention；
In figure: 1- latex water dropper；2- inner tube outlet；3- microscale sampler outer tube；4- inner tube
Specific embodiment
A kind of microscale sampler suitable for being used in glove box, including microscale sampler outer tube 3, microscale sampler outer tube
3 tops are latex water dropper 1, have inner tube 4 in the inner lower of microscale sampler outer tube 3, the top of inner tube 4 is inner tube outlet 2, cream
, which there are left and right ends in the junction of glue water dropper 1 and microscale sampler outer tube 3 respectively, 2 " W " ripple muscle
Before use, first demarcating to microscale sampler, by way of weighing, the volume of microscale sampler is calculated.
Then microscale sampler wash clean is dried.
In use, being inserted into microscale sampler wait take in solution, hand is pinched water dropper 1 and is bubbled in the solution, then unclamps water dropper
1, using the principle of atmospheric pressure, solution is allowed slowly to be inhaled into inner tube 4, but is answered in sparging process incremental and each
Bubbling amount should not be too many, repeats bubbling movement and allows solution sucking inner tube until when solution overflows on a small quantity from inner tube outlet 2, has sampled
Finish, pipetted liquid volume is that sampler demarcates volume.
The utility model patent is small in size, easily operated, economy and durability, accuracy are high, is suitable for glove box, draught cupboard etc.
Quantifying for micro-example pipettes during radioactive sample analysis in closed environment.
