Spectrum3/Spotlight400系统可以测量多达750µm平方大区域的ATR锗晶体进行ATR成像测量。该系统还可以获得超过20万个具有高信噪比的光谱数据点,并进行分析操作以便在短时间内实现AMP提取和鉴别。 我们描述了一种利用FTIR ATR成像系统分析空气中微塑料的方法。 通过对从大气中收集的颗粒进行适当的预处理,ATR成像系统能够检...
The vibrational spectrum of partially crystalline poly(ethylene terephthalate), PET, appears to be unduly complex in that the absorption bands are split into amorphous and crystalline modes and are sensitive to chain configuration and orientation. Assignment of the bands has accordingly proved to be ...
location of peaks from the second derivative inverse spectra. Curve-fitting results were deemed acceptable when all the component frequencies were within a ±1 cm-1 range in comparison to the input frequencies and the sum of all the components was concurrent to the experimentally measured spectrum....

This peak corresponds to v(C = O) in DMDHEU-based reagent as compared with FTIR spectrum of DMDHEU-based reagent in Fig. 2. These peaks show stable intensity shifts to 1695 cm− 1 in spectra of cotton fabric treated with DMDHEU-based reagent and various amount of sericin because of ...
The Raman Analysis was conducted using a confocal Raman spectrometer (NTEGRA Spectra II, NT-MDT Spectrum Instruments) operating in a back-scattered geometry. The sample was illuminated with a monochromatic laser operating at a wavelength of 633 nm, which was focused on the sample surface by applyi...
