Two-dimensional (2D) materials have been extensively explored for the manufacture of transparent electrodes, sensors, solar cells, display devices, energy and halogen storage, and diverse composite materials because to their unique chemical, mechanical, physical, and electrical capabilities. Understanding the characteristics of 2D materials and the outcomes of their applications requires accurate characterization of their elemental makeup.
CHNSO elemental testing is available from Alfa Chemistry to determine the percentages of carbon (C), hydrogen (H), nitrogen (N), sulfur (S) and oxygen (O) in 2D materials. Graphene oxide, for example, is a complex material that shows the presence of various oxygen functional groups, so we characterize its composition with our CHNSO elemental analysis method. Please contact us as soon as possible so that we can assist you with your 2D material testing!
Why CHNSO Analysis
Alfa Chemistry's CHNSO elemental analysis, also known as organic elemental analysis or elemental trace analysis, is a dependable and cost-effective technology that may be utilized for a wide range of goods and materials. We can help customers quickly determine the amount of C, H, N, S and O present in inorganic and other types of materials. CHNSO testing can be applied to a variety of sample types, including solids, liquids, volatile samples and viscous samples.
The approach may be used to determine the purity and chemical composition of a number of sample types, including solids, liquids, volatile, and viscous materials. Understanding the organic element composition also aids the analyzer in determining the structure of the sample material. Chemical characterization of organic compounds is used for research and quality control (QC).
The most common technique for CHNSO elemental analysis is based on the combustion of the sample. The sample creates a homogenous composite of the elements C, H, N, and S upon burning. These combustion products are measured using gas chromatography to determine the proportion of elements in the original sample.
