WebWhen looking to focus the beam to small areas of interest, we will use a micro-ATR accessory on the FTIR bench to focus the beam to a single bounce ATR crystal. With optical observation capability through the ATR cell we can position the sample to make intimate contact with the ATR crystal with the irradiating area occupying approximately 0.2mm ... WebJan 23, 2024 · ATR FTIR analysis is limited, in that if the gel layer extends beyond 0.5 µm, no further changes in FTIR would be seen. The information depth can be extended by using a lower refractive index ATR crystal, such as zinc sulfide, which would extend the information depth to 1.5 µm, albeit with a reduction in sensitivity.

WebFTIR stands for Fourier Transform InfraRed. It is a commonly used spectroscopic technique for molecular analysis. The technique works by infrared light being either absorbed or transmitted by the molecular bonds in a sample (Colthup et al., 2012). This process produces a spectrum with signals that are characteristic of the bond vibrational ...

WebThe PIKE MIRacle ATR accessory, in conjunction with an Agilent Cary 670 FTIR or 660 FTIR spectrometer achieves a limit of detection of 0.04% and 0.08% v/v EtOH/H 2 O respectively. These results reflect the high energy throughput of the Agilent Cary 600 FTIR series of FTIR spectrometers and demonstrate the Webinstruments, but the higher–quality spectra are obtained using FTIR spectrometers. ATR is one of the most versatile sampling techniques that requires little or no sample preparation for most samples. It only requires that the samp le is placed in intimate contact with the IRE crystal, which achieved by pressing the solid onto the crystal with ...
