FT-ICR is a powerful type of mass spectrometry, co-invented by the Magnet Lab's Alan Marshall, particularly suited to identifying heavy molecules. (Java tutorial)

Oscillators are a type of circuit found in many types of electronic equipment, including clocks, radios and computers. (Java tutorial)

Mass spectrometers are machines that give scientists a look at the composition and origin of a material by analyzing and quantifying its atoms and molecules. This tutorial shows how a dual sector mass spectrometer works. (Java tutorial)

Mass spectrometers are machines that give scientists a look at the composition and origin of a material by analyzing and quantifying its atoms and molecules. This tutorial shows how a single sector mass spectrometer works. (Java tutorial)

The mass spectrum of a material, deduced using a machine called a mass spectrometer, reveals how many isotopes of a given element are to be found in the material. See here what these spectra look like and how they are useful. (Java...

Learn about the important role the petri dish plays in enabling the study of microorganisms, some of its uses, and how petri dishes are used.
