Description

Sample dehumidification dust removal filter equipment

Technical Field

The utility model relates to a filter technical field specifically is a sample dehumidification dust removal filter equipment.

Background

Gas is one of four basic states of matter (the other three being solid, liquid, plasma, respectively). The gas may be composed of a single atom (e.g., a rare gas), a single molecule composed of one element (e.g., oxygen), a compound molecule composed of a plurality of elements (e.g., carbon dioxide), or the like. The gas mixture may include a plurality of gaseous species, such as air. A significant difference between gases and liquids and solids is that the spacing between gas particles is large. This spacing makes it difficult for the human eye to detect the colorless gas. Gas, like liquid, is a fluid that can flow and be deformable.

When a gas chromatograph is used for analyzing gas samples, some samples often contain moisture or water vapor, the moisture and the water vapor are not required to be recorded in sample components, and the moisture easily causes blockage of a chromatograph sample introduction system and pollution or failure of a chromatographic column and needs to be separated and removed. However, the general filtering device has high cost and inconvenient use, reduces the detection efficiency of personnel, and is inconvenient to detect different gases.
