Elemental Analysis (EA)

Product Name Elemental Analysis (EA) Product Overview English Introduction: Elemental Analysis (EA) is a classic microanalysis technology for accurately determining the mass proportion of carbon, hydrogen, nitrogen, sulfur and oxygen (CHNS/O) elements in materials. It serves as a core detection method for qualitative and quantitative analysis of material components, substance structure deduction, purity judgment and modification mechanism research, and is widely used in polymer materials, organic compounds, biomass materials, new energy powders, chemical additives, composite materials and environmental samples. Relying on the Thermo Scientific FlashSmart fully automatic elemental analyzer from the United States, this test adopts the principle of high-temperature combustion cracking and chromatographic separation detection, which can complete combined CHNS test and independent oxygen element test respectively. It accurately outputs the mass percentage of each element and directly reflects the organic component composition, impurity content and functional group element proportion of materials, providing accurate quantitative data for material formula analysis, synthesis process verification, modification mechanism research and product purity calibration. The test only requires 20mg trace powder sample. The equipment features high detection sensitivity, strong anti-interference ability and excellent data stability. The test results comply with national and international general detection standards, and can be directly used for scientific paper publication, patent data support, project conclusion reports, enterprise raw material quality inspection and finished product component calibration.
