Description:

Chemical analysis is an absolute quantification method that calculates the quantity of the component to be measured based on the amount of the sample, the amount of reaction product, or the amount of consumed reagent and the stoichiometric relationship of the reaction. Instrumental analysis is another important method of analysis, which is a relative quantification method based on a standard calibration curve.

Chuangxin Testing uses analytical instruments such as mass spectrometers, spectrometers, chromatographs, and nuclear magnetic resonance spectrometers to perform qualitative and quantitative analysis of substance composition, enabling professional analysis of complex samples with multiple components, allowing for formulation improvement and product performance enhancement.

Objectives of Composition Analysis:

1)Understand raw material composition and quality control;

2)Analyze product composition and deduce the basic formulation;

3)Prove the absence of certain components;

4)Investigate the causes of product performance decline;

5)Determine component content to understand product performance;

6)Solve problems in the production process;

7)Compare products of the same model from different periods;

8)Quickly identify the causes of unknown substance generation and eliminate hidden dangers;

9)Improve product formulation and imitate production.

Application Fields of Composition Analysis:

1.Solids, liquids, gases, powders, solvents, raw materials, particles, materials, organic substances, inorganic substances, etc.
