Recently, a customer inquired about using our Energy Spectrum TechnologyThe iCAN9 Fourier transform infrared spectrometer was used to test whether the sample they provided (PP Felt) contained silicone oil.The European Pharmacopoeia has also issued corresponding national standards in China for the control of infrared spectroscopy for polymer materials, including the General Principles for Infrared Spectroscopy Analysis (GBT 6040-2002) and Microbeam Analysis Energy Dispersive Spectroscopy Quantitative Analysis (GB/T 17359-2012). We strictly follow this national standard for the samplespolypropylenefeltPerform infrared spectroscopy for substance content determination.
