Background technology
In recent years, using laser ablation as receiving the laser ablation Plasma-Mass Spectroscopy of input mode, laser ablation etc. more from
The features such as equipment such as sub- mass spectrum or laser ablation spectrum is because of micro-zone in situ, high accuracy, low test limit, high performance-price ratio, extensive use
In fields such as physical material, geological and mineral, environmental energy, basic scientific research and application study are advanced significantly.Due to such
Being designed as the micro-zone in situ constituent analysis of solid sample the sample bin and sample stage of equipment more, thus be difficult to apply to liquid into
Analysis, so as to limit the application of the kind equipment.
Utility model content
For the problem that above-mentioned background technology is present, the utility model provides a kind of being applied in laser ablation as entering
Carry out the dropping liquid plate servicing unit of micro-volume liquid component micro-zone in situ analysis in the analytical equipment of sample loading mode.
Therefore, the utility model uses following technical scheme：A kind of microcell suitable for the analysis of micro-volume liquid component is former
Position dropping liquid plate, it is characterized in that, including the dropping liquid plate being molded is made by Teflon material, form multiple protrusions in the top surface of dropping liquid plate
Overflow platform, the apical side height of overflow platform is concordant, and spaced certain distance between overflow platform forms Qi Keng footpaths equal on overflow platform
One or the circular dropping liquid hole of heterogeneity indent, the hole bottom in circular dropping liquid hole forms smooth curved surface, described dropping liquid plate all weeks
Side outer rim is formed and can be used to fix the draw-in groove of dropping liquid plate.
Used as the supplement to above-mentioned technical proposal and perfect, the utility model also includes following technical characteristic.
Described dropping liquid plate is rectangle, big between the overflow platform being arranged on rectangle dropping liquid plate and circular dropping liquid hole
Small equal, overflow platform is in multiple rows of setting arranged in parallel.
Described dropping liquid plate is rounded, and the size between the overflow platform being arranged on circular dropping liquid plate and circular dropping liquid hole is not
It is homogeneous.
The curvature that the hole bottom in circular dropping liquid hole forms smooth curved surface is 60 degree.
Following beneficial effect can be reached using the utility model：The utility model simple structure, it is with low cost, it is easy to make
With can significantly expand the range of application that receives the equipment such as Plasma-Mass Spectroscopy laser ablation Plasma-Mass Spectroscopy or laser ablation and should more
With space, possess stronger practical value and economic worth.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is rectangle dropping liquid plate structure schematic diagram of the present utility model.
Fig. 3 is circular dropping liquid plate structure schematic diagram of the present utility model.
Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1-Figure 3, in analytical equipment of the laser ablation as input mode carry out micro-volume liquid into
Divide the dropping liquid plate servicing unit of micro-zone in situ analysis, its structure snd size can be according to the universal sample of laser ablation sample introduction equipment
Target, general is that the rectangle of Teflon material or circular slab are constituted, and several or dozens of size is distributed on slab homogeneous or not
Homogeneous dropping liquid hole 2, hole bottom smooths, about 60 degree of radian, and each dropping liquid hole periphery is the overflow platform 3 fair with the edge in hole, often
Individual dropping liquid hole 2 and overflow platform 3 constitute a unit, fluted between each unit, are liquid isolation channel, and slab periphery is card
Groove, draw-in groove depth is highly identical with overflow platform 3, about 0.5 millimeter.
The utility model is cleaned, then be washed with deionized water using preceding during the priority of dropping liquid plate 1 is placed in into strong acid and absolute alcohol
Only, then with absorbent cotton cotton swab dip in absolute alcohol wipe one by one each dropping liquid cheat 2, after alcohol volatilization after, by testing liquid by
One instills dropping liquid hole 2, and overflow platform 3 is slightly higher than to liquid level.It is general using a monoblock after all dropping liquid holes 2 fill testing liquid
Analysed film covers these dropping liquids hole 2, and because the liquid levels in dropping liquid hole 2 are higher than overflow platform 3, unnecessary liquid can overflow drop
Liquid hole 2, a part is laid on overflow platform 3, the surface tension of generation can firmly adsorption analysis film, so as to cause each to drip
Liquid hole 2 turns into a unit for sealing；The liquid that another part overflows flows down from overflow platform 3, into isolation channel, so as to keep away
The union dyeing that each dropping liquid cheats fluid sample between 2 is exempted from.Behind analysed film absorption jail, the dropping liquid plate of film capped is placed in sharp
In the sample bin that light degrades, dropping liquid plate is fixed on the position of draw-in groove, it is to be measured.
The utility model provide in analytical equipment of the laser ablation as input mode carry out micro-volume liquid
The dropping liquid plate servicing unit of composition micro-zone in situ analysis, its structure snd size can be according to the universal sample of laser ablation sample introduction equipment
Target, can design that multiple or dozens of size is homogeneous or inhomogenous dropping liquid is cheated according to different size, thus can simultaneously contain number
Individual or dozens of fluid sample, carries out batch quantity analysis, exempts the trouble for frequently changing sample；Each dropping liquid hole size is small, required
Amount of liquid is few, minimum only to need 100 microlitres of liquid, can avoid the misgivings that composition cannot be detected accurately caused by liquid dilution for many times；
Each dropping liquid hole has 60 degree of gentle radian, and hole bottom smooths, and reduces the surface tension of liquid, beneficial to dropping liquid plate before and after analysis
And wiping, the cleaning in dropping liquid hole；Each dropping liquid hole periphery there is smooth overflow platform, be easy to dropping liquid cheat contain liquid after use it is thin
Film cover, it is to avoid analyze test process in because volatilization and caused by composition union dyeing；There is isolation channel between the unit of each dropping liquid hole,
Beneficial to the liquid that dropping liquid hole is overflowed is accommodated, also ensure that the liquid in each dropping liquid hole will not be with other liquid union dyeing；Whole dropping liquid
Plate is designed as Teflon material, strong alkali-acid resistance, thus is applicable to the analysis of different liquid components；The hardened structure of whole dropping liquid
Simply, with low cost, it is easy to use, can expand significantly receive Plasma-Mass Spectroscopy laser ablation Plasma-Mass Spectroscopy or laser ablation more
Range of application and application space etc. equipment, possess stronger practical value and economic worth.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appending claims and its equivalent thereof.
