Embodiment Construction

[0030] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these examples are used to illustrate the present invention and not to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not indicated are usually the conditions in routine experiments.

[0031] Example Figure 1~3 As shown, the universal sampling device for polymorphic samples includes a sealed solid sample inlet 1 and a liquid sampler, a magnetic drive device 3, a box body 8 and a sealing device, and the sealing device includes a sampling positioning device 5 and a gas path Connecting device 6, the magnetic drive device 3 drives the liquid sampler to inject samples through the drive rod 4; the magnetic drive device 3 non-contact drives the solid sample inlet 1 to inject samples. The sample inj...

Abstract

The invention discloses a polymorphic sample universal sampling device which comprises a sealing solid sampling port (1) and a liquid sampling device. The device is characterized by also comprising a magnetic driving device (3), and while the magnetic driving device (3) drives the liquid sampling device to sample through a driving rod (4), the magnetic driving device (3) drives the solid samplingport (1) to sample in a non-contact driving mode. In the device, the liquid sampling and the solid sampling are combined into a whole, and the magnetic driving device is not in contact with the solidsampling port and the liquid sampling device, thereby guaranteeing the gas tightness of the solid sample and the liquid sample during sampling; and an analyzed and detected data result is reliable and stable, thereby avoiding carbon deposition problems caused by the condition that the speed of the liquid sampling device cannot be controlled during sampling and the problem that a plurality of sampling devices need to be changed because of switching the solid sample and the liquid sample.

Description

technical field [0001] The invention belongs to the technical field of elemental analysis, and in particular relates to a universal sampling device for multi-form samples that is common to solid and liquid samples. Background technique [0002] The elemental analyzer analyzes and measures the different contents of elements in the gas produced after the combustion of combustible substances, and whether the combustion of combustible substances is sufficient or not directly affects the accuracy of the test results. These combustible substances can be combustible liquids or solids. Therefore, all elemental analysis instruments have the key equipment of sample cracking device. This equipment is often used in microcoulomb method, ultraviolet fluorescence method and chemiluminescence method to measure the content of sulfur, chlorine, nitrogen and other elements in petroleum and volatile solid samples. These samples were lysed with a sample lyser and analyzed for their components....
