Abstract
The invention concerns fluorescence standards, and in particular fluorescence standards for calibrating optical detectors. According to the invention, a fluorescent mineral or mixtures of minerals are employed for use as a fluorescence standard. The fluorescent mineral can be a naturally occurring mineral or a synthetically produced mineral. Preferred fluorescent minerals for use as fluorescence standards are corundum, fluorite, turquoise, amber, zircon, zoisite, iolite or cordierite, spinel, topaz, calcium fluorite, sphalerite or zincblende, calcite or calcspar, apatite, scheelite or calcium tungstate, willemite, feldspars, sodalite, a uranium mineral, a mineral containing Al3+, and in particular ruby and sapphire.
Claims24
A sample plate for accommodating at least one sample, the plate being adapted to be accommodated in an optical measuring instrument that uses fluorescence measurement, and the plate being a well plate in which multiple wells extend completely through the well plate and the size of the wells is dimensioned such that a sample introduced into the wells is held in the wells against the force of gravity as a result of capillary forces, wherein a fluorescent mineral and/or a substance that includes a fluorescent mineral, for use as a fluorescence standard, is removably located in at least one of the wells of the well plate, and has a shape that corresponds substantially to the shape of wells of the well plate.
