The definition of the pretreatment system

The pretreatment system is to process the samples extracted in the production process to meet the requirements of the detector for the sample state. Generally, dust, steam, fog, harmful substances and interference components in the sample to be analyzed are removed, and the pressure, flow and temperature of the sample are adjusted to ensure that the sample meets the service conditions specified by the analyzer. 
In order to ensure that the sample entering the analytical instrument is suitable for the specified conditions required by the operation of the instrument, so as to avoid the influence of interfering components in the sample on the side quantity of the instrument, the sample sent from the sampling system must be pretreated before entering the instrument J. the pretreatment system can stabilize the pressure, filter, cool, dry, separate, volume Dilution and other operations; The solid samples can be cut, ground, processed and formed. The pretreatment system has a great impact on the application quality of analytical instruments, and varies greatly due to different samples, so it needs special research and design.
