Abstract

The utility model discloses a disposable split-type trace volume sample pool. The disposable split-type trace volume sample pool is characterized by comprising two transparent glass pieces, wherein a sample detection area is defined by bonding a double faced adhesive tape at the edge of one of the glass pieces. When a sample is measured, the sample is dropwise added at the central position of the detection area; and a sealed sample chamber is formed by closing and bonding the two glass pieces through the double faced adhesive tape. The disposable split-type trace volume sample pool can be used for measuring a trace sample, and is particularly suitable for the situation that a tested sample is sparse; the sample is measured in the form of a thin film, wherein the thickness of the sample can be about 1 to 10 mu m at least, while the thickness of the sample can be only made into 1 mm at most by using the conventional sample pool; the disposable split-type trace volume sample pool is convenient to use and measure, and high in efficiency, and the sample does not need to be fed or emptied by using a piette filling/emptying device; and by using the disposable sample pool, the pollution risk is reduced greatly, a cleaning agent is not required to use, and simultaneously, the measurement cost is reduced.

Description

Disposable split type micro-volume sample pond

Technical field

The utility model relates to a kind of measurement of fluid sample, is specifically related to a kind of disposable split type micro-volume sample pond.

Background technology

Sample cell is an indispensable device of measuring the optics of liquids performance, and traditional sample cell mostly is a column, and the top of sample cell has sample holes, and fluid sample injects the sample chamber through sample holes, seals with adhesive tape and measures.The micro-example pond has also appearred in the measurement to micro-example at present, and the generally I of the endoporus thickness in this micro-example pond reaches about 1mm, because size is little; Often need transfer pipet filling/emptier to carry out sample introduction and emptying; And after each the measurement, be difficult for cleaning, spent more time and clean-out system usually; Can't guarantee to clean whether totally, influence Measuring Time and precision greatly.If also have the amount of sample extremely rare, adopt existing micro-example pond still can not satisfy the needs of measurement, therefore need develop a kind of novel micro-volume sample pond, to satisfy the needs of measuring.

Summary of the invention

The utility model technical matters to be solved is to the above-mentioned state of the art a kind of disposable split type micro-volume sample pond to be provided; Sample is measured with the form of film; Its thickness is little, and cost is low, easy to use simultaneously, and disposable use can be avoided polluting.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of disposable split type micro-volume sample pond; It is characterized in that said disposable split type micro-volume sample pond comprises two transparent glass sheets; Wherein the edge of a glass sheet is pasted with double faced adhesive tape and surrounds equally article detection zone; During measuring samples, sample drop is added on the center of detection zone, and two blocks of glass sheet are pasted the sample chamber that involutory back forms sealing through double faced adhesive tape.

As improvement, said glass sheet is water white dull and stereotyped quartz glass plate, and two blocks of glass sheet are rectangle, and measure-alike.

At last, the thickness of said double faced adhesive tape is 10um～5mm, and the one side of double faced adhesive tape is bonding with glass sheet, and another side is covered with one deck separate paper before bonding.

Compared with prior art, the advantage of the utility model is:

1, can measure micro-example, be specially adapted to the rare situation of sample; Sample is measured with the form of film, about the I to 10 of its thickness micron, can only accomplish 1 millimeter and traditional sample cell is the thinnest;

2, easy to use, need not to use transfer pipet filling/emptier to carry out sample introduction and emptying, it is convenient to measure, efficient is high;

3, disposable sample cell greatly reduces the risk of pollution, need not to use detersive, has reduced the cost of measuring simultaneously.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in the figure, a kind of disposable split type micro-volume sample pond comprises two colourless transparent glass sheets 1 and 2; Glass sheet 1 and 2 is two identical dull and stereotyped quartz glass plates; Be shaped as rectangle, wherein the edge of a glass sheet 1 is pasted with double faced adhesive tape 3 and surrounds equally article detection zone 4, during measuring samples; Sample drop is added on the center of detection zone 4, and two blocks of glass sheet 1 and 2 are pasted the sample chambers that involutory back forms sealing through double faced adhesive tape 3; The thickness of said double faced adhesive tape 3 is 10um～5mm; Double faced adhesive tape 3 is selected good, difficult and other material generation chemical reaction of stable material quality property for use; To guarantee the accuracy of sample detection; The one side of double faced adhesive tape 3 is bonding with glass sheet 1, and another side is covered with one deck separate paper before bonding with glass sheet 2, so that store.

During use, tear separate paper, sample drop is added in the center of the detection zone 4 of glass sheet 1; Another piece glass sheet 2 is covered on the glass sheet 1, paste through double faced adhesive tape 3 and fix, sample is just measured with the form of film like this; About the I to 10 of its thickness micron, satisfy the needs of small sample test, adopt disposable use can avoid polluting simultaneously; Need not to use detersive, reduced the cost of measuring simultaneously.
