Description

Technical Field

[0001] The utility model relates to the field of chemical detection equipment, in particular to an on-line analyzer based on ultrasonic detection. Background Technique

[0002] Liquid-phase detection technology is widely used in many fields such as chemical analysis, environmental monitoring, food safety, and medicine. Traditional liquid-phase detection methods mainly include liquid chromatography, gas chromatography, electrochemistry analysis, spectroscopy analysis, and titration analysis, etc. These methods have a relatively high level in terms of detection accuracy and sensitivity, and can effectively analyze and detect various components in the liquid phase. However, when facing liquid-phase detection under some specific conditions, these traditional methods may encounter certain limitations.

[0003] First of all, traditional liquid chromatography and gas chromatography rely on the separation process of samples. For liquid samples that are relatively turbid, have a darker color, or have a lower light transmittance, the separation effect may be affected, resulting in inaccurate detection results. In addition, these methods usually require complex sample pretreatment and expensive instrument equipment, with cumbersome operation steps and high costs.

[0004] Secondly, spectroscopy analysis relies on the optical properties of samples, and analyzes sample components by measuring the absorption, emission, or scattering of samples to specific wavelength light. However, when the turbidity of the sample is relatively high or the color is relatively dark, the light transmittance and scattering will be significantly reduced, thus affecting the detection sensitivity and accuracy.

[0005] In order to overcome the limitations of the above traditional methods, researchers have begun to explore new detection technologies that can accurately determine the characteristics of the liquid phase without relying on the transparency or color of the samples. Content of the Utility Model
