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.
Aneroid barometers are often used for reading pressure in homes and recreational boats. Other uses may include barographs in meteorology and altimeters in modern aircraft. Aneroid barometers primarily measure whether pressure is rising or falling. This type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense. There are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level. Another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper. When used in this capacity, the aneroid barometer can store a week's worth of data.
