And a kind of quantitative enrichment facility of multipassage rotary evaporation of the dark opaque liquid of processing.
Background technology
Autosampler can be injected liquid by the mutual cooperation of suction pumps, aspirating needle in tail pipe concentration cup, or
Liquid assimilating after person's rotary evaporation will quantify after quantitatively concentrating comes out.
Wherein, rotary evaporation, which quantitatively concentrates the liquid level judgement of tail pipe part and liquid quantitative mode, traditional method, three
Kind mode：The first, sub-cooled is without sensor type.The part heating other than the tail pipe of cup is concentrated, tailpipe point is immersed in low
In warm environment, the evaporation of tail pipe partially liq is prevented, it is quantitative to achieve the purpose that.Second, non-contact capacitive sensor
Judge liquid level.Tail pipe part is equipped with capacitance sensor, can be carried out to the liquid level of tail pipe partially liq across glass tail pipe wall

Next four work steps of the present invention are elaborated in conjunction with Fig. 3 A- Fig. 3 D and Fig. 4 A, Fig. 4 B.
The first step：As shown in Figure 3A, aspirating needle 4 under the driving of autosampler X/Y arms 5 from autosampler chassis 1
Initial position be moved to the surface of second liquid container 3, and penetrated to the second liquid under the driving of autosampler Z arms 6
Inside body container 3, needle point is located at dark opaque 19 liquid level of liquid in 3 inside of second liquid container or less.Suction pumps 11 drive depth
The opaque liquid of color 19 passes sequentially through second liquid container 3, aspirating needle 4 and finally reaches liquid line 7.Aspirating needle 4 automatically into
Under the driving of sample device Z arms 6, it is lifted away from second liquid container 3, and under the driving of autosampler X/Y arms 5, be moved to sealing cover 8 just
Top.Aspirating needle 4 moves downward under the driving of autosampler Z arms 6, and needle point is located inside tail pipe concentration cup 18.Then, it inhales
Liquid pump 11 drives dark opaque liquid 19 to pass sequentially through liquid line 7, aspirating needle 4, and sealing cover 8 finally reaches tail pipe concentration
Cup 18.Aspirating needle 4 is lifted away from sealing cover 8 under the driving of autosampler Z arms 6, and sealing cover 8 is closed, this quantitatively inputs liquid process
Terminate.
Second step：As shown in Figure 3B, the beginning of electric rotating machine 15 is rotated with specific rotating speed.By being connected to above
Eccentric wheel 14 drive sensor holder 13 centrifugal rotation movement is done with specific rotating speed.The drive of sensor holder 13 heating muff 12,
Visual sensor 16, concentration cup packer ring 17, tail pipe concentration cup 18, concentration cup sealing block pad 9, concentration cup sealing nut
10, sealing cover 8, dark opaque liquid 19 do centrifugal rotation movement with specific rotating speed together.Heating muff 12 starts to warm up
And heat is endlessly provided, temperature concentrates cup 18 by tail pipe and is eventually transferred to dark opaque liquid 19, dark impermeable
Continuous to evaporate after light liquid 19 is heated in offline rotational movement process, volume is constantly reduced, until reaching quantitative body
Product, this heating rotary evaporation process just terminate.
Third walks：At the beginning, as shown in Figure 4 A, visual sensor 16 starts to acquire tail pipe in real time dense rotary evaporation process
Opaque 19 image of liquid of dark color of 18 tail pipe part of contracting cup, and algorithm is compared by itself software image of visual sensor 16
Carry out the liquid level situation for monitoring dark opaque liquid 19 uninterrupted in real time.But under similar circumstances, as shown in Figure 4 B, traditional
Photoelectric sensor optical signal launch end 20 and photoelectric sensor optical signal receiving terminal 21 can not monitor dark opaque liquid in real time
The specific location of 19 liquid level of body, to make whole process fail.In the present invention, when dark opaque 19 liquid level of liquid reaches tail pipe
When concentrating the tail pipe determined volume of cup 18, visual sensor 16 obtains the signal that liquid level is detected, then by Compare System
Visual sensor 16 signals to system, and image information is preserved and is transferred to system.Once liquid level reaches tail pipe and concentrates cup
18 tail pipe part, as shown in Figure 3 C, system control electric rotating machine 15 are stopped rotating movement, simultaneity factor control heating muff 12
Stop heating, this dosing process terminates.
4th step：Aspirating needle 4 is moved to the surface of sealing cover 8, aspirating needle under the driving of autosampler X/Y arms 5
4 under the driving of autosampler Z arms 6, move downward, and as shown in Figure 3D, it is impermeable that needle point is located at tail pipe concentration 18 bottom dark color of cup
Below 19 liquid level of light liquid.Then, the dark opaque liquid 19 after the driving of suction pumps 11 is quantitative passes sequentially through aspirating needle 4, liquid
Body pipeline 7.Then, aspirating needle 4 moves upwards under the driving of autosampler Z arms 6.Then, aspirating needle 4 is in autosampler
Under the driving of X/Y arms 5 and autosampler Z arms 6, it is moved to inside the first liquid container 2.Then, the driving of suction pumps 11 is quantitative
Dark opaque liquid 19 afterwards passes sequentially through liquid line 7, aspirating needle 4, finally reaches inside the first liquid container 2.Imbibition
Needle 4 is lifted away from the first liquid container 2 under the driving of autosampler Z arms 6, this takes liquid process to terminate, and prepares next batch
The rotary evaporation of liquid quantifies concentration process.
The advantage of the invention is that：
Apparatus of the present invention, can be by dark opaque Full-automatic liquid by autosampler, aspirating needle and suction pumps
It is injected into tail pipe concentration cup or removes tail pipe concentration cup.
