What are the commonly used instruments for analytical chemistry products?

The commonly used instruments for analytical chemistry products include the following:
Mass spectrometer: used to analyze the molecular structure and composition of substances by ionizing molecules in the sample and conducting mass analysis.
Gas chromatograph (GC): used for separating and analyzing compounds in gas or liquid mixtures, achieved by the difference in distribution coefficients between the stationary and mobile phases of the sample.
Liquid Chromatography (LC): Used for separating and analyzing compounds in liquid mixtures, achieved by the difference in distribution coefficients between the stationary and mobile phases of the sample.
Spectrophotometer: Used to measure the absorbance of a substance solution and analyze the concentration or reaction kinetics of a substance by measuring the intensity of the absorbed light.
Nuclear Magnetic Resonance Spectrometer (NMR): Analyze the chemical structure of a substance by measuring the signal of atomic nuclei in a sample.
Electronic balance: used for precise weighing of samples, with the characteristics of fast, convenient, and intelligent.
PH meter: used to measure the acidity or alkalinity of a solution, determining the pH value by measuring the negative logarithm of the concentration of hydrogen ions in the solution.
Viscometer: used to measure the viscosity of samples, widely used for viscosity measurement of oil products, coatings, adhesives, etc.
These instruments play an important role in analytical chemistry, assisting researchers in material analysis, structural identification, and quantitative determination. For example, a mass spectrometer can determine the molecular weight and structure of compounds, gas chromatography and liquid chromatography are used to separate and purify mixtures, a spectrophotometer is used to determine the concentration of substances, and a nuclear magnetic resonance spectrometer provides information on the internal structure of molecules.
