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

What is Ocular Micrometer? Working Principle of Ocular Micrometer The principle of an ocular micrometer revolves around using a calibrated scale to accurately measure the size of objects viewed through a microscope. This scale, typically divided into 100 divisions, each measuring 0.01 millimeters (µm), is an essential component placed within the eyepiece of the microscope. … Read more

What is Toolmakers Microscope? Principle of Toolmakers Microscope The working principle of the toolmakers microscope relies on the principles of optics, similar to a conventional light microscope.
