Our Services

Component Qualitative Analysis Services

The analysis of constituents provides an assessment of the material and its classification based on its chemical compounds. Through the use of sophisticated analytic tools such as infrared spectroscopy (IR), nuclear magnetic resonance (NMR), mass spectrometry (MS), and X-ray diffraction (XRD), we can find out the elements, compounds, and functional groups contained in different materials. We help clients appreciate the chemical composition of materials and lay a scientific foundation for the clients to select, optimize, and innovate on various materials.

Component Quantitative Analysis Services

The services that we provide have been set up to carry out a quantitative analysis of materials with a definite emphasis on computing the quantity of each component in a substance. With the help of HPLC, Atomic Absorption Spectroscopy, and Inductively Coupled Plasma Mass Spectrometry, we provide customers with results at micro or trace levels. Through this service, we can help our clients achieve the desired product quality, supervise the production process, comply with the necessary laws and regulations, and rigorously achieve their goals regarding quality control and product consistency.

Methods of Analyzing the Composition of Materials

Considering that the composition of materials is a requirement of any scientific theoretical or industrial practical activity, composition analysis is imperative for ensuring product quality, enhancing technology progress, and protecting people and the surrounding environment in a safe manner. Methods of analysis employed are as follows:
