then the images recorded with a conventional microscope using basic illumination lack the necessary contrast needed to reveal critical details. Staining is used to highlight important features of the tissue by enhancing tissue contrast. This improves the investigator's ability to draw conclusions, such...
Also, extracted components can be organic, such as additives and monomers, or inorganic, such as metals or salts. Generally, the following analytical techniques are used to determine the different classes of unknowns:Organic UnknownsVolatile Gas Chromatography Mass Spectroscopy (GCMS), Dynamic ...

Mass Spectrometry & SpectroscopyHow Does UV Spectroscopy Work?Request information Of all the techniques available to scientists, UV Spectroscopy is one of the most useful. The characterisation tool is used across a wide range of industries, from forensics and pharmacology to astronomy and food ...
As the name suggests, AE Spectroscopy uses an energy source such as a flame, arc, spark or plasma to excite atoms. This triggers a shift in energy levels and forces the atoms to release radiation at specific wavelengths. The intensity of this radiation is measured by a specialized instrument...
