Ultrafast automatic sampling switching system

Abstract

The invention discloses an ultrafast automatic sampling switching system which comprises a cabinet and a centralized control screen, a negative pressure fan is longitudinally arranged at the bottom end of the inner wall of the cabinet on the rear side of an isolation cabinet door, and the inner wall of the cabinet above the negative pressure fan is divided into a left analysis chamber and a right sampling chamber. A first sampling box, a second sampling box and a sampler are sequentially and longitudinally arranged on the inner wall of the right sampling chamber on the outer side of the gas receiving guide plate from bottom to top, a purging device is vertically arranged on the inner wall of the right sampling chamber above the sampler, and PN2PURGE, TOC ON-LINE, IC ON-LINE and Ultra-fast AMCON-LINE are sequentially and fixedly arranged on the inner wall of the left analysis chamber from bottom to top. The centralized control screen is transversely arranged in the middle of the upper surface of the isolation cabinet door at one end of the cabinet away from the observation window. According to the present invention, the Ultra-fast AMC ON-LINE is adopted to increase the sample collection data amount while the overall reaction time of the analysis instrument equipment is shortened, and the purging device is arranged on the inner wall of the right sampling chamber above the sampler so that the influence on the reliability of the subsequent detection due to the residue after the sample switching can be effectively avoided, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of sample sampling, in particular to an ultra-fast automatic sampling switching system. Background technique [0002] Sampling, also known as sampling, refers to the process of converting a continuous quantity in the time domain or space domain into a discrete quantity. Also refers to the process of converting analog audio to digital audio. The number of samples taken per second is called the sampling frequency. The number of sampling bits can be understood as the resolution of the capture card processing sound. Sampling is to convert an analog signal that is continuous in time and amplitude into a discrete analog signal that is discrete in time (there is a fixed interval in time) but still continuous in amplitude under the action of the sampling pulse. So sampling is also called the discretization process of the waveform. The process of converting a continuous signal into a discrete signal is called a s...
