    Abstract: A light source for near-infrared transmission and reflection spectroscopy can be constructed from a combination of a high power blue or blue-green light emitting diode (LED) and a phosphor element based on an inorganic material. The phosphor element absorbs the LED light and, in response to the LED excitation, emits luminescence that continuously covers the 700-1050 nm range. One possible material that can be used for such a near-infrared emitting phosphor element is a single crystal rod of Ti+3 doped Sapphire. An alternative near-infrared emitting phosphor material is a disk or rectangular shaped composite of Ti+3 doped Sapphire powder embedded in a clear optical epoxy or silicone encapsulant. Such a combination of a blue LED for excitation of a phosphor element that emits in a broad wavelength band has been widely used in white LEDs where the emission is in the 400-700 nm range.

    Abstract: In one embodiment, active (continuous or intermittent) passivation may be employed to prevent interaction of sticky molecules with interfaces inside of an instrument (e.g., an infrared absorption spectrometer) and thereby improve response time. A passivation species may be continuously or intermittently applied to an inlet of the instrument while a sample gas stream is being applied. The passivation species may have a highly polar functional group that strongly binds to either water or polar groups of the interfaces, and once bound presents a non-polar group to the gas phase in order to prevent further binding of polar molecules. The instrument may be actively used to detect the sticky molecules while the passivation species is being applied.
