Detailed Description
As shown in FIG. 1, the present embodiment provides an autosampler cleaning assembly comprising a cleaning tank for the autosampler and an autosampler 4;
one end of the automatic sampler 4 communicates with the cleaning liquid storage container 10, and the other end is a liquid outlet.
As shown in fig. 1 and 2, the wash tank of the autosampler includes a wash tank body;
the cleaning tank body consists of a cleaning position 1 and a waste liquid position 2;
the cleaning position 1 and the waste liquid position 2 are separated by a partition;
the top of the partition is provided with a fluid channel;
the fluid channel is communicated with a cleaning position 1 and a waste liquid position 2;
the waste liquid level 2 has a waste liquid discharge port 3 at the bottom.
The specific process for realizing the cleaning of the sampling tube by utilizing the cleaning tank or the assembly comprises the following steps:
s1, moving the sample injection needle 4 to a cleaning tank through a mechanical arm or a lifting grabbing mechanism, and inserting the sample injection needle into the cleaning position 1 to enable a liquid outlet end of the sample injection needle to be close to the bottom.
S2, the cleaning liquid in the cleaning liquid container 10 is pumped or gravity-fed into the sample injection needle, so that the cleaning liquid flows out along the directions of (5) - (6/7) - (8), and is finally discharged from the waste liquid discharge port 3.
Wherein, the water flow direction is 5 hours, realized the washing of injection needle inner wall.
When the water flows to 6/7, the outer wall of the sampling needle is cleaned.
When the water flows to the water level 8, the waste liquid overflows from the cleaning position 1 to the waste liquid position 2 by means of overflow.
In addition, in consideration of the case where the waste liquid level overflows if the waste liquid discharge port fails to discharge in time when the waste liquid region is full, and the case where the waste liquid contaminates the sampling tube again if it flows into the cleaning region, in a modification of the present embodiment, a check valve is further provided on the fluid passage, that is, a one-way flow of the liquid is realized.
In addition, consider the washing to the washing tank, if go on through the mode that overflows all the time, the condition of hydrops can take place for certain reason in the final washing position, if do not shift out this washing tank and wash through the manual work, can lead to the hydrops to remain in equipment all the time, be unfavorable for electronic equipment's maintenance like this. Therefore, in the modification of the present embodiment, it is proposed that an openable and closable valve structure is provided at the bottom end of the partition, so that after the analysis of the whole day is completed, the effect of discharging all the cleaning liquid can be achieved by opening the valve.
