Detection range

Qualitative analysis is the qualitative analysis of the research object. The main analysis methods are dry analysis and wet analysis. The samples used in dry analysis do not need to be made into solutions, while the samples used in wet analysis need to be mixed into solutions. Common solvents include water, acid solutions and alkali solutions. Insoluble solvent sample can be sodium carbonate, sodium peroxide, potassium sulfate and other fluxes to melt the sample decomposition, and then dissolve in water or dilute acid. Quantitative analysis methods include chemical analysis method and instrumental analysis method, while chemical analysis method mainly includes volumetric analysis method and gravimetric analysis method. Instrumental analysis mainly includes gas chromatography, rigorous liquid chromatography, electrochemical analysis, optical analysis, mass spectrometry and so on.

The test items

Dry method analysis: the samples used need not be made into solutions, such as bead analysis, flame color analysis, atomic emission spectrometry, X-ray fluorescence spectrometry, etc.

Wet method analysis: the sample should be mixed into solution, the common solvents are water, acid, alkali solution. Insoluble solvent sample can be sodium carbonate, sodium peroxide, potassium sulfate and other fluxes to melt the sample decomposition, and then dissolve in water or dilute acid.
