Abstract

The invention discloses an online sampling device and an online sampling method for an X-ray fluorescent spectrograph. The device comprises a sampling pool main body, a motion guide rail, a fixed mass block, a bearing, an overflow pipe, a correcting baffle, a correcting sheet, a test through hole, a sample storage groove, a thin soft rope, a float bowl, a sample inlet pipe, a sample outlet pipe, an inlet valve and an outlet valve. By using the device and method provided by the invention, the online sampling and test of liquid samples are realized, the test efficiency is increased, and the labor intensity of worker is relieved. By adjusting the position of the correcting baffle through gravity and buoyancy, the use of electronic elements is avoided. The device has high safety performance and can be used for testing inflammable and explosive petroleum products. Since the height of the overflow pipe is adjustable, the height of liquid level is adjustable, and further, the distance between an X-ray probe and a sample is adjustable; therefore, the device has certain flexibility in test.

Description

technical field [0001] The invention relates to a technology for collecting samples on-line and sending them into a sample storage tank for testing by an X-ray fluorescence spectrometer, in particular to an on-line sampling device and an on-line sampling method for an X-ray fluorescence spectrometer. Background technique [0002] At present, X-ray fluorescence spectroscopy is more and more widely used in petrochemical industry. Its method has a wide range of analytical elements, a wide range of analyzable concentrations, high sensitivity, small matrix effect, and strong anti-interference ability. The most notable feature is that it does not destroy the sample, and the sample can be solid, pasty, liquid or solution. In terms of analyzing the sulfur content of oil products, compared with other methods, X-ray fluorescence spectrometry has the characteristics of simple operation, fast analysis, improved analysis efficiency and reduced labor intensity. [0003] For X-ray fluores...
