Modularization luminosity analyzer for instrumental analysis experiment teaching

Abstract

The invention discloses a modular photometric analyzer for teaching of instrumental analysis experiment. The analyzer has the advantages of simple structure and low cost, and can be convenient for students to operate and is beneficial to enhancing the practical experiment ability of the students. The analyzer comprises a dark box (10), a power supply module (20), a quartz sample cell (12) which is arranged in the dark box (10), a fluorescence photoelectric conversion module (30) and an ultraviolet light photoelectric conversion module (50) both of which are arranged on the dark box (10), the fluorescence photoelectric conversion module (30) is electrically connected with a first signal processing and display module (40), and the ultraviolet light photoelectric conversion module (50) is connected with a second signal processing and display module (60). The analyzer is mainly used for teaching instrumental analysis experiment, help students fully master theoretical basic knowledge, fully exerts the activity of the students and greatly enhances the experiment skills of the students by a fully opened and small-sized modular self-assembly experimental mode.

Description

Technical field [0001] The invention relates to an analysis instrument, in particular to a photometric analyzer used for the teaching of instrument analysis experiments. Background technique [0002] Chemistry is an experimental science, and the experimental link plays an important role. Instrumental analysis and experimentation is an important basic course of chemistry, involving various fields of chemistry and other related disciplines. It is a comprehensive teaching course involving a wide range of disciplines. It is also an important course for chemistry students in the future. And the main tools and means of research. [0003] At present, the photometric analyzers used in university teaching are mainly large-scale photometric analyzers dedicated to laboratories, such as ultraviolet-visible spectrophotometers and fluorescence spectrophotometers. This large-scale photometric analyzer highly integrates power supply system, optical system, signal processing and analysis system a...

AI Technical Summary

Problems solved by technology

This large-scale photometric analyzer is highly integrated with power supply system, optical system, signal processing and analysis system and analysis software, and its price is very expensive.

As a large-scale photometric analyzer teaching aid, it can only be operated by teachers or assistants, so it can only serve as a demonstration, which is not conducive to improving students' experimental ability

In addition, the large-scale photometric analyzer has a high level of digitization and automation, which is a black box for students, which is unpredictable and brings unnecessary fear to students' learning.
