Colorimetry- a comprehensive guide for your color science

Overview of Colorimetry Colorimetry, as the name suggests, means measurement of colors. In terms of chemical analysis, it is, more specifically, the measurement of the concentration of a particular compound (solute) in a colored solution (solvent). During scientific work, we often need to measure quantities of a particular compound in…

The Basics of Infrared Spectrophotometry

Spectroscopy refers to the interaction between electromagnetic (EM) radiation and matter as a function of its frequency or wavelength. From this, a number of quantitative and qualitative measurements defining aspects like sample concentrations, structure, chemical compositions etc, can be obtained depending on the spectroscopic technique and spectrum of EM radiation…

Laboratory Safety Rules and Guidelines

Preston Brown, a graduate student at Texas Tech University was working on the highly energetic nickel hydrazine perchlorate (NHP) in early January 2010 when an almost fatal accident that scarred him for life occurred. In a series of events that involved disregard for his supervisor’s guidelines, failure to wear safety…

Mastering the Microtome

Description of Microtome Generally, microtomes are involved in the process of preparing samples of biological material to be examined under a microscope. Specifically, they slice material into extremely thin pieces so they can fit in a microscope slide and be studied by researchers. It holds the material in place while…

Spectrophotometer

The spectrophotometer is a common optical device that measures the intensity of light relative to color (or wavelength). In the lab, they are used to determine how much light is absorbed by a colored chemical dissolved in solution. This allows us to calculate the concentration or purity of chemicals, analyze…

Understanding and Using Acids

An acid is a chemical, which when added to water, increases the amount or concentration of hydrogen ions, or H+, making it acidic. A hydrogen ion (H+) is just a hydrogen atom without its electron. And, as a hydrogen atom is just one electron and one proton, the term hydrogen…

Difference Between Acids and Bases

Acids and Bases play an important role in chemistry. We see them everywhere in our day to day lives, from our cleaning agents; soaps and detergents, to baking soda. Acids and bases (alkaline earth metal chemical element) are 2 categories of corrosive substances. Any compound with a pH value between…

Acids and Bases Overview

What are acids and bases? These are the chemicals that make water either acidic or alkaline. Acids make water acidic, while bases make it alkaline. To understand acids and bases properly though, we’ll need to look at water first. Water is a simple, yet complicated chemical. We’ve all heard that…
