Abstract
The invention discloses a quick filtration and adsorption method for full-automatic oil measurement. The filtration and adsorption are carried out through a filter device and an adsorption device. Tube, the inner tube is made of polytetrafluoroethylene material, the outer tube is made of silica gel material, and connected to the nitrogen gas source, the inner tube is the reagent pipeline, the outer tube is the gas pipeline, and the sampling gas tube is connected to the entrance of the bottle through the frosted port; The bottle body is provided with three-stage filter agents or adsorbents with a single particle size in sequence from top to bottom. The bottom of the bottle body is sealed by a sand core filter plate, and the bottom is connected to the oil outlet pipe through a detachable frosted port. This invention avoids damage to the target object. Non-specific adsorption speeds up the filtration speed, inhibits bacterial growth, and improves the filtration and adsorption effect and efficiency.
Description
technical field [0001] The invention relates to a fast adsorption and filtration device for automatic oil measurement, which is used for adsorption and filtration of moisture and impurities by a fully automatic infrared oil measurement instrument, and belongs to the technical field of analytical chemical sample pretreatment. Background technique [0002] With the development of social economy and the continuous improvement of industrialization level, the pollution of water resources in the human living environment is becoming more and more serious, and it has received more and more attention. At present, the pollution sources of environmental water come from oil extraction and processing, petrochemical industry, etc. Oil pollution in industrial production activities accounts for a considerable proportion, and the detection of oil content in environmental waters has become increasingly important. The current detection mainly uses infrared oil detectors and infrared methods for...
