Abstract
The utility model provides an automatic sampling device of an on-line TOC (Total Organic Carbon) analyzer. The automatic sampling device comprises a peristaltic pump, a flowmeter, a multi-channel switching valve, a plurality of sampling bottle units and a controller, the flow speed of the peristaltic pump is adjustable within the range of 0-42 ml / min. During use, different sample injection flow rates can be set according to the type of an online TOC analyzer to be detected, the flow meter is used for detecting the flow in a pipeline, and after standard liquid in one sample injection bottle is used up, the multi-channel switching valve is automatically switched to another sample injection bottle for continuous supply of the standard liquid. The used standard solution can be stored by a sample injection bottle after being prepared in a laboratory, and the sample injection bottle is sealed by a spiral sealing cover before detection. During on-site detection, after the spiral sealing covers of the sample injection bottles are opened, the sample injection bottles are respectively placed under different glands, and automatic continuous sample injection detection can be carried out. The device is convenient to carry and use, is high in universality, and improves the detection efficiency.
