Chemistry basics The reason why chemistry touches everything we do is because almost everything in existence can be broken down into chemical building blocks. The main building blocks in chemistry arechemical elements, which are substances made of a singleatom. Each chemical is unique, composed of...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
"Gold standard" means quality and dependability. Sanger sequencing is the gold-standard DNA sequencing method that powered the Human Genome Project and continues to generate highly accurate, reliable sequencing. We know that reliable results are important to you. That’s why we have dedicated...
What is an analytical concentration in analytical chemistry? Types of Concentrations: The concentration of a substance can be measured in several ways. It may be grams over liters (gram concentration), moles over liters (molar concentration), or mililiters per 100 mililiters (volume concentration...

Analytical chemistry is one of the basic things kids do at school when they are first starting chemistry, or even general science. I can remember being given a gas (usually mixing a couple of chemicals in order to get the gas through a reaction) and being told to identify the gas through...
