Portable sample analysis preprocessor and usage

Abstract

The invention relates to a portable sample analysis preprocessor. The portable sample analysis preprocessor is characterized in that through connectors and an electric controller, a preprocessing unit, a ventilating unit and an exhaust gas treatment unit are electrically connected; a rotator of the preprocessing unit is mounted at the circle center of a base plate, an ultrasonic generator and an electromagnetic agitator are separately fixed in a recess of the base plate, a buffer tank, a scrubber tank and a sucking pump are connected together through pipelines in sequence in the exhaust gas treatment unit IV and are fixed in a case, and the gas inlet end of the buffer tank is connected to the ventilating unit. A usage is as follows: the ventilating unit is locked on a vertical post by a cardan joint link rod and is supported over a reactor, and a pipeline communicates with the ventilating unit and the exhaust gas treatment unit; and a control program is called on a display screen to control concentration, exhaust and exhaust gas treatment operations. The portable sample analysis preprocessor solves the problems of complex operation, slow sample preprocessing and environmental pollution and operator harming caused by produced and volatilized toxic and harmful gas and reagent in the process of sample preprocessing, and the objective of quick, efficient and pollution-free sample processing is achieved.

Description

technical field [0001] The invention belongs to chemical experiment equipment, relates to chemical teaching experiments related to chemical analysis, scientific research and other industry analysis and inspection commonly used application tools, and a portable sample analysis preprocessor. Background technique [0002] In the process of chemical analysis teaching experiments, scientific research and other industrial analysis and inspection operations, the test samples need to be pretreated before the inspection. When processing samples for different samples and different detection indicators, in addition to adding corresponding reagents, it is also necessary to Other experimental conditions have been changed many times, such as: ultrasonic, infrared, temperature control, stirring, and quantitative or trace addition. The processed sample solution is concentrated or evaporated to near-dryness to reduce the loss of corresponding detection indicators, thereby reducing analysis a...
