Problems solved by technology

However, due to the complexity of the process, unqualified sampling technology and high cost of later use of the instrument, foreign testing instruments have not been promoted in China.
There are also some general analysis instrument manufacturers in China that develop ion concentration detection products, but they are mostly used in

Abstract

The invention provides a detection device, and mainly relates to a no-clean detection device. By changing a positioning mode of a solution sample, a no-clean effect is achieved. The detection device comprises a spectrophotometer, an acoustic levitation apparatus and an auxiliary positioning device. According to the no-clean detection device, by an ultrasonic levitation technology, a to-be-detected sample is levitated in the air, wherein the to-be-detected sample is placed at an ultrasonic standing wave stabilizing center by the auxiliary positioning device. Absorption or transmittance of the to-be-detected sample can be measured by spectrophotometer so as to complete substance color characteristic measurement of the sample. After measurement is completed, recovery and cleaning of the to-be-detected sample can be completed by an absorption device. The device provides a convenient and environmental-friendly measurement method so as to avoid pollution of sample residues or residual liquid to the testing environment pollution of an equipment system.

Description

field of invention [0001] The invention relates to a detection device, in particular to a detection device without cleaning. Background technique [0002] At present, in the field of spectrophotometric detection equipment, there are usually different detection equipment for solutions and solids. When detecting the color characteristics of a sample to determine the concentration of ions or substances contained in the sample, the comparison of transmission spectra, that is, colorimetry, is often used. In the detection of solid samples, since the sample does not produce deformation or micro-deformation, the sample positioning can be completed by the fixture. The effective area in the center of the sample is not damaged during positioning. For the detection of the solution, it must be placed in the position to be tested after being placed in a container. This measurement method has requirements on the transmittance, capacity accuracy, and shape of the vessel, and the used ves...
