What Is Chemical Detection?

Chemical inspection

Right!

a) Chemical analysis: Chemical analysis is performed through a known, quantitatively completed chemical reaction.
Gravimetric analysis: A method for determining the content of a component to be measured based on the weight of a chemical reaction product.
· Titration analysis method: It is a method of adding a known accurate concentration of a reagent (called a standard substance) to the measured component solution, and calculating the content of the measured component based on the volume of the standard solution consumed when the reaction is completed. .
b) Instrument analysis: Instrument analysis is to obtain the component to be measured by measuring the physical and chemical properties of the sample such as optical properties (such as absorbance and turbidity) and electrochemical properties (such as current, potential, and conductance) with the help of special optoelectronic instruments Content method. Commonly used instrumental analysis methods are optical analysis, chromatographic analysis, and electrochemical analysis.
