Spectrometry 1

Non-microscopic Characterization
Category General
Difficulty Level Normal
Audience Level General
Description Optical microscopy, Scanning probe microscopy and Electron microscopy are known as microscopic techniques. Other methods such as Spectrophotometry, Chromatography, BET and etc. are classified as non-microscopic characterization. Non-microscopic characterization is incorporated in this course.
Overview
The term “non-microscopic” is used when Optical microscopy, Scanning probe microscopy and Electron microscopy are not used to determine materials’ quantity and quality. Pieces of information such as what element and how much of it are in a component, specific surface area and etc. are determined using non-microscopic methods.


Booklet
Description
 It starts with talking about the two branches of spectrometry and their definitions. Then it talks about the interactions between light and material, different parts of the equipment and talks about Beer–Lambert law and the mechanism and application of UV-visible and Infrared Spectroscopy (IR) equipment.
Mental Challenge
 What is spectrometry based on?
Quizzes and Activities
 Activity: Draw a schematic of a spectrometry equipment, including the path of the entering light and the material.
