Dissecting Microscope (Stereo Microscope) Definition, Uses, Parts, Principle.

Published on March 17, 2024 • Written by BNO Team

Stereo microscopes, in contrast to compound light microscopes, often employ reflected illumination, or light reflected off an object’s surface, rather than transmitted (diascopic) illumination. When a specimen is too thick or opaque for compound microscopy, reflected light from the object enables for investigation. Unlike a compound microscope, transmitted illumination in most stereo microscopes is not … Read more

Ion exchange mechanism in Ion Exchange Chromatography

Last Updated March 17, 2024 • 0 revisions • Written by BNO Team

Ion exchange chromatography (IEC) is a chromatographic technique that allows for the separation of ions and polar molecules based on their charge. It utilizes a stationary phase composed of an insoluble matrix with covalently bonded charged groups. These charged groups can attract and bind ions of the opposite charge present in the mobile phase, which … Read more
