A kind of high-efficiency and continuous ice core depollutes device
The present invention relates to a kind of efficient, high resolving power and continuously ice core to depollute device.
During glacier is usually located at, the high altitude localities of low dimension and south, Arctic, harsh physical environment makes drilling through of ice core abnormal difficult, and cost is extremely expensive, is all generally jointly to be provided funds by domestic, international Duo Jia scientific research institution and joint study completes.Because the sample obtained is very limited, ice core product often need to be divided into multiple secondary ice core and deliver to domestic, international different laboratory and carry out physics, chemistry and bioanalysis with the demand of satisfied different research project.Because the trace element analysis of ice core is very high to the requirement of polluting, therefore generally gets the core of ice core as secondary ice core, and further it is depolluted.The decontamination method of traditional ice core trace element analysis is ice core level or vertical unsettled placement and is fixed at two ends above the device that depollutes, then machining away the part of ice core external contamination by rotating ice core, obtaining the analysis that the clean sample in the inside is used for the chemical compositions such as trace element.Although tradition ice core depollutes, device can obtain the clean ice core product of low resolution (10-20cm) or high resolving power (4-5cm), effectively meets the needs of ice core trace element research, but still Shortcomings, show as:
The tradition ice core device that depollutes is only applicable to depolluting of single ice core, cannot depollute continuously to the whole Zhi Bingxin more than 30cm.The ice core length that field drills through is generally about 60-100cm, therefore traditional ice core device that depollutes must be cut into ice core the single ice core of different size (as low resolution 10-30cm or high resolving power 4-5cm), so not only add workload, also destroy continuity and the integrality of ice core simultaneously, easily cause the fragmentation of ice core, the more important thing is and very easily cause new pollution (pollution as cutting section) in the process of cutting and packing, thus finally affect the effect of depolluting of ice core.
Tradition ice core depollute apparatus structure complexity, needs sample size comparatively large, adding up, it is complicated to pollute flow process, requires larger workload, directly affects the efficiency of depolluting; Secondly, the tradition ice core single ice core in device that depollutes is unsettled placement, after a joint ice core has depolluted, the process of unclamping or block ice core from two ends, easily causes ice core to drop from the device that depollutes, probably cause the fragmentation of clean ice core, cause loss and the pollution of sample; The taking of multiple single ice core, fix, depollute, depollute after transfer and packaging etc. thereof add operating time, delayed the process of depolluting, reduced the efficiency of research work.
