As long as in addition, the non-structure each other of technical characteristic involved in subsequent described different embodiments of the present invention
It can be combined with each other at conflict.
In the following, the present invention proposes part preferred embodiment to instruct those skilled in the art to realize.
Fig. 1 is the structural schematic diagram for cascading autosampler that an embodiment provides, and showing one kind can cascade automatically
Sample injector, this can cascade autosampler it is vdiverse in function, can efficiently reciprocal sample presentation and convenient for cascade host be sampled inspection.
Figure 10 is the partial structural diagram that autosampler can be cascaded in Fig. 1.
Referring to Fig. 1 and Figure 10, one kind can cascade autosampler, comprising: bottom plate 1 and the sample presentation subgroup 4 being set on bottom plate 1
Subgroup is operated before sampling at least one.Wherein, bottom plate 1 is equipped with sample area 3 to be measured, and the middle layer of bottom plate 1 is placed equipped with board
Position, board place position for placing sample injector board and host board.
Sample presentation subgroup 4 is located at the side in sample area 3 to be measured, and it is to be measured that the sample rack for transporting sample loading pipe enters sample
Area 3.
It also is equipped with sample recovery area 5 in the side of sample presentation subgroup 4 on bottom plate 1, for recycling the sample after having inspected
Frame.Operation subgroup is located at the side of sample presentation subgroup 4 before at least one sampling, to operate before carrying out the sampling of sample.Sample is to be measured
The side in area 3 can cascade host with sample detection.Operation subgroup includes but is not limited to load subgroup 8, rotary scanning before sampling
Group 6 shakes up subgroup 7, push pipe subgroup 11, unloading subgroup 9 and urgent sample introduction subgroup 10.
Load the entrance that subgroup 8 is used to promote sample rack sample presentation subgroup 4.Rotary scanning subgroup 6 is for reading sample tube
On identification information.It shakes up the crawl of subgroup 7 sample tube and shakes up sample so that host punctures sample tube sampling.Push pipe subgroup 11 is forward
Movement is withstood sample tube and is sampled so that host punctures.Sample rack after unloading subgroup 9 is used to have inspected promotes sample recycling
Area 5.Urgent sample introduction subgroup 10 is for being inserted into the sample tube for needing promptly to detect to sample area 3 to be measured.
Preferably, the structure for capableing of reciprocal sample presentation can be set into sample presentation subgroup 4, to realize reciprocal sample presentation.
In the present embodiment, pass through setting bottom plate 1 and operation before the sample presentation subgroup 4 being set on bottom plate 1 and at least one sampling
Subgroup, bottom plate 1 are equipped with sample area 3 to be measured, and sample presentation subgroup 4 is located at the side in sample area 3 to be measured, for transporting sample loading pipe
Sample rack enter sample area 3 to be measured, operation subgroup is located at the side of sample presentation subgroup 4 before at least one sampling, to carry out sample
Sampling before operate, the side in sample area 3 to be measured can cascade host with sample detection, to realize efficient sample presentation, will collect originally
It is integrated into sample injector at subgroup is operated before examining the sampling that may separate out in equipment, realizes automatic cascade host to sample
It is sampled detection, improves checkability, reduces and examines equipment volume and weight, reach sample injector and host can modularized production
With the purpose of pipeline system cascade cooperation.
It should be noted that operation refers to the operation before host is sampled the sample tube in sample rack, example before sampling
Such as, sample tube tag recognition or sample tube sample such as shake up at the operation.In the prior art, operation is only sample presentation behaviour before sampling
Make, and execute sample presentation operation, the executing agency for the operations such as sample tube tag recognition or sample tube sample shake up is arranged at
In host, to cause that host is bulky, heavier-weight.
It is independent by operation subgroup before executing the executing agency of sample presentation and the sampling of execution sampling operation in the present embodiment
It is designed to that one kind can cascade autosampler, so that a kind of completely new sample injector is invented, so that all hosts can make
Operation before carrying out sample presentation and sampling with the sample injector, reaches host and sample injector can modularized production and pipeline system cascade cooperation
Technical effect.
In addition, to remove formation from host completely new for the executing agency operated before detecting the samplings of different sample item destination hosts
Sample injector after, sample injector, which can cascade, cooperates different host, while the volume and weight of host get a larger optimization, no
Only convenient for operating with, and avoid repeating to be arranged resulting in waste of resources.
