Teaching plan of "Instrument Analysis"

This chapter is an introduction to the course "Instrument Analysis". Mainly to let students understand the connection and difference between "Chemical Analysis" and "Instrument Analysis", the classification of instrument analysis methods and its development, and introduce the evaluation indicators of instrument quantitative analysis methods. The focus is on several indicators for evaluating analytical methods. The class hour plan is 1 class hour.

Section 1 Introduction to Instrument Analysis

Abstract: The difference and connection between instrument analysis and chemical analysis, the classification and development trend of instrument analysis methods.

Key Difficulties: Classification of Instrumental Analysis Methods

Teaching method: Lecture

1. Instrument analysis and chemical analysis

â’ˆChemical analysis definition

â’‰Definition of instrument analysis

â’ŠThe difference between the two is:

â‘ Testing ability

â‘¡Demand of samples

â‘¢Analysis efficiency

â‘£Extensive use

⑤Accuracy

2. Classification of instrument analysis methods

According to the measurement principle and signal characteristics, instrument analysis methods are roughly divided into four categories

â’ˆOptical analysis method

Analysis methods using electromagnetic radiation as the measurement signal, including spectroscopic and non-spectral methods

â’‰ Electrochemical analysis method

An analytical method based on the electrochemical properties of the substance in solution

â’Šchromatography

Separation and analysis are based on the difference in the distribution ratio between the two phases (mobile phase and stationary phase).

â’‹Other instrument analysis methods

Including mass spectrometry, thermal analysis, radiological analysis, etc.

3. Overview of the development of instrumental analysis

development trend

â’ˆThe wide application of computer technology in instrument analysis has realized the automation of instrument operation and data processing.

â’‰Combining different methods to improve the function of instrument analysis.

â’ŠThe mutual penetration of various disciplines
