HIGH-SPEED SAMPLE FEEDING DEVICE Russian patent published in 2013 - IPC G01N33/48 G01N35/10 

FIELD: chemistry.

SUBSTANCE: device for feeding samples into an analysis device has: first and second sample feeding channels, each having a section for loading and inputting samples, a tube for holding samples and a control valve; a position switching valve for successive connection of said first and second channels with the device; a channel for feeding cleaning liquid into said first and second channels; a sample input channel which is linked to said first channel or said second channel through the position switching valve; and a valve for selecting washing liquid which is meant for selecting washing liquid or system liquid for feeding into said first and second channels, such that the cleaning liquid and the system liquid successively flow on the first and second channels. The group of inventions also relates to a sample analysis method according to which samples are fed through one channel while cleaning the other channel.

EFFECT: group of inventions provides high rate of analysing multiple samples over a short period of time, high rate of washing the system with cleaning liquid.
