Fig. 3: Hyperspectral image for qualitative analysis.
From: High-speed scanless entire bandwidth mid-infrared chemical imaging
a Reflected electron image of a 5 microchannels device. b Optical microscopic image of microchannels device injected with 5 samples obtained before the measurement of mid-infrared hyperspectral imaging. c Mapped the mid-infrared hyperspectral image, from left to right are glycerin, glucose, albumin, 1,2-dioleoyl-sn-glycero-3-phosphocholineglucose and soybean oil. The mapped color is a pseudo-color. d Each MIR transmittance spectrum of each sample shown in c. The black lines are infrared transmittance spectra of the 5 samples measured in a vacuum (4 Pa) by FT-IR (JASCO, FT/IR-6100). e Images corresponding to fifteen different individual wavelength components. A movie (Supplementary Movie 1) of the 2D image while the wavelength is continuously scanned over the entire mid-infrared bandwidth.
