WAY AND DEVICE FOR AUTOMATIC LOADING OF TESTS OF LIQUID CHROMATOGRAPHY Russian patent published in 2009 - IPC G01N35/10 G01N1/00 

FIELD: physics.

SUBSTANCE: group of inventions refers to a way and the device for automatic loading of tests of liquid chromatography. The way of automatic loading of test includes installation of a removable tip on a sampler with use of the automatic manipulator for a liquid. Thus the sampler forms a part of the automatic manipulator for a liquid. Then sampler moving by the automatic manipulator for a liquid is carried out in a loading position near to the test. Test loading in a removable tip is carried out with use of the automatic manipulator for a liquid. After that the sampler is moved by the automatic manipulator for a liquid in an introduction position near the port for tests introduction. Then insertion of the removable tip is carried out in the internal channel of the port for tests introduction, and the internal channel has a ring shoulder so the removable tip densely fits to the ring shoulder, and test introduction from a removable tip in the internal channel of the port for tests introduction. Thus the port for tests introduction is executed with an inlet opening of a port for an insert of the removable tip installed on a sampler of the automatic manipulator for a liquid. The port has the internal channel going from an inlet port opening, and the basis of the port executed as a part of the internal channel. The automatic manipulator for a liquid contains the device of sampler movement, a sampler installed on a console of the device of sampler movement, a syringe pump, connected with a sampler when operating, the control unit, connected with the syringe pump when operating to call aspiration of a test through the sampler, and a port for test introduction. Thus the introduction system contains the automatic manipulator for a liquid, the introduction valve and the junction circuit for the liquid medium, connecting the basis of the port for test introduction with the introduction valve.

EFFECT: decrease of the analysis time and decrease of cost of test processing.
