Analytical Instruments
The technology behind visible light microscopes, the oldest true laboratory instruments, has not changed much in fundamental operation in 200 years.
Time-of-flight (TOF) mass spectrometry (MS) works by imparting equal energies to all fragments. Since smaller particles thereby travel faster, their masses are determined by how quickly they travel from the source to the detector.
Integration is the main reason for the virtual disappearance of the specialist GC or MS supplier that produces chromatographs for someone else’s mass detector, and vice versa.

Fourier transform infrared (FTIR) spectroscopy, a subset of infrared (IR) spectroscopy, uses a mathematical algorithm, Fourier transform, to translate raw infrared data into a spectrum.
An analytical method that involves generating charged molecules or molecular fragments and measuring their mass-to-charge ratio through the ionization of chemical samples, mass spectrometry (MS) is a key part of many laboratories.
A newly developed carbon nanotube material could help lower the cost of fuel cells, catalytic converters and similar energy-related technologies.
Classical methods for protein quantitation rely on colorimetric assays, such as those involving protein-copper chelation (bicinchoninic acid (BCA) and Lowry assays) and dye-binding based detection (Bradford and “660 Assay”) or ultraviolet (UV) spectroscopy.
