Far-IR spectra in the range of 1800-50 cm -1 were gathered using a solid substrate beamsplitter and a DLaTGS detector with a polyethylene window. Polyethylene is typically used as a window material in ...

In order to show the correlation with traditional FTIR spectra, the acquired spectra were evaluated against a standard FTIR database (KnowItAll, Bio-Rad Inc.). The ~30 nm tall contamination residue ...

FT-NIR spectra of dextrose (blue), 6-mil polyethylene bag (green), and dextrose inside a 6-mil polyethylene bag (magenta) For that reason, the main test in using near-infrared spectroscopy is getting ...
