FTIR in Plastics and Polymer Identification: Key Applications and Advantages
Leer másFTIR Accessories (Fourier Transform Infrared Spectroscopy) has become an essential analytical tool for identifying plastics and polymers. The principle of FTIR relies on the characteristic absorption of infrared light by different functional groups in polymer molecules. By comparing the sample spectrum to a spectral database, FTIR enables rapid qualitative, quantitative, and structural analysis. Its applications […]

Background Interference in FTIR Analysis: Sources and Effective Elimination Methods
Leer másIn FTIR Accessories, background interference has a direct impact on baseline flatness, peak shape accuracy, and the reliability of both qualitative and quantitative analysis. Uncontrolled interference can obscure weak absorption bands, distort spectral features, and compromise reproducibility, particularly in trace or high-precision measurements. To support routine laboratory operation and troubleshooting, the most common sources of […]

Five Key Factors Affecting the Resolution of Infrared Spectroscopy
Leer másThe resolution of infrared spectroscopy determines how clearly spectral peaks are separated, how accurately peak positions are identified, and how reliably overlapping signals can be analyzed. In Fourier Transform Infrared Spectroscopy (FTIR Accessories), resolution is not controlled by a single parameter but by a combination of hardware performance, optical quality, and data processing settings. The […]
