Pressure, therefore the work negative pressure in first waste liquid pool 11 can be maintained in OK range all the time, first waste liquid
Pond 11 can carry out waste collection to multiple passages in waste liquid generation device simultaneously, so as to further increase at the waste liquid
Manage the liquid waste processing efficiency of device 1.Furthermore because first waste liquid pool 11 is always maintained at negative pressure state, it is not necessary to carry out just
Negative pressure switches, therefore the gas circuit consumption of the liquid waste treating apparatus 1 is relatively low, reduces the energy consumption of the sample analyser 100.Institute
The first waste liquid pool 11 that liquid waste treating apparatus 1 had both collected waste liquid using negative pressure is stated, also includes collecting under malleation driving
Second waste liquid pool 16 of the waste liquid of discharge, therefore the liquid waste treating apparatus 1 collects caused waste liquid, example under various environment
The waste liquid in multiple reaction tanks in the reaction unit 4 as described in can be collected by first waste liquid pool 11, the detection means 5
In the waste liquid that is flowed out of flow chamber can be collected by second waste liquid pool 16, it is useless in the sample lines of the sampling apparatus 3
Liquid can be collected by second waste liquid pool 16.
It should be understood that " negative pressure " refers to the gas pressure less than normal pressure (one atmospheric pressure of namely what is often called) in the utility model
Power state.In the utility model, the waste drains pump 13 and the negative pressure source 12 can be that first waste liquid pool 11 foundation is negative
Pressure, can be set as by the controller 14：The foundation and maintenance of the work negative pressure in first waste liquid pool 11 are main
It to be responsible for by the negative pressure source 12, the waste drains pump 13 mainly helps out (such as during discharge waste liquid while build pressure),
So that each part of the liquid waste treating apparatus 1 coordinates and operation is more reasonable efficient, the work of the liquid waste treating apparatus 1
Make more efficient.
