WebThe user simply places a sample directly into the infrared (IR) beam. As the IR beam passes through the sample, the transmitted energy is measured and a spectrum is generated. However, the analyst must often prepare the sample into a pellet, mull, film, etc. before the transmission measurement can be made. This requires expertise and can be ... Web1220–1120 cm-1 on an Agilent Cary 660 FTIR and Cary 670 FTIR spectrometer (Table 2). Using the commonly accepted definition of LOD, a sample of EtOH in H 2 O is detectable if it has a peak height ~3 times the p-p noise. Using the calibration curve previously collected, this translated to an LOD of 0.04% on a Cary 670 FTIR and 0.08% on a Cary ...
