Fluorite Properties Fluorite is made up of calcium fluoride and has a transparent or translucent appearance. Sometimes it can be a colorless crystal, but other times it can also be purple, blue, green, yellow, or pink, or other combinations of these colors. Fluorite is sometimes called fluorspar. The name is derived from the Latin word âfluoâ, meaning to flow.
A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light.These parameters are used to identify the presence and the amount of specific molecules in a medium.he machine is constructed like this to decrease the stray light from the upper beam that may strike the detector. The optimal angle is 90 degrees. There are two different approaches to handling the selection of incident light that gives way to different types fluorometers.
The emission filter further screens the light, the emitted light is measured by the detector, and the fluorescence value is displayed on the instrument. Figure 2 illustrates the key components of a filter fluorometer: light source/lamp; excitation and emission filters; sample cell/cuvette; and light detector.or example, if the substance is linear to 250 ppm and measurable with a calibration curve to 1000 ppm, you might calibrate with a 200 ppm standard and take readings at 500, 750, and 1000 ppm for a calibration curve. In some cases, calibration with a standard of known concentration is not necessary.
