title = "Nondispersive and multichannel analyzers based on mid-IR LEDs and arrays",
abstract = "This paper briefly describes the fabrication of infrared light emitting diodes by liquid phase epitaxy including both InGaAs LEDs for emission wavelengths from 2.5 to 3.8 micrometers and InAsSbP for wavelengths from 3.8 to 4.7 micrometers. Some of the first applications of these LEDs in spectroscopic instrumentation are described together with the main instrument characteristics. Nondispersive analyzers have been developed for CH4 and CO detection utilizing LED sources emitting at 3.3 and 4.7 micrometers, respectively. A novel infrared spectrometer construction has been developed based on a linear LED array emitting at 3.3 micrometers and a fixed grating monochromator. This miniature construction can be used as an electrically scanned spectrometer module in future IR analyzers for portable and process on-line applications.",
