It is no secret to researchers who homogenize tissue samples as part of their regular laboratory routine that the job can be messy and loud, and produce results that are sometimes inconsistent. read more

Analysis of cells and cellular processes in biological and medical research requires systems for imaging as well as tools for manipulating and dissecting cells and subcellular structures. read more

Size exclusion chromatography (SEC) and dynamic light scattering (DLS) are common technologies in protein laboratories. read more

For more than 30 years, 2-D electrophoresis has been used by researchers around the globe to separate proteins by charge and then by size. read more

Analytical chemists have long known that closed-vessel microwave sample preparation techniques are the most reliable way to achieve high-quality digestions—i.e., clear, precipitate-free solutions... read more

Thermogravimetric analysis (TGA) is an established technique for studying the thermal stability of materials and for determining and understanding their decomposition profiles. read more

In 1981, two research scientists from IBM’s European research facility in Rueschlikon, Switzerland, made a discovery that would help change the face of the world today. read more

Sample introduction has been a problem for analytical chemists for decades. In 1984, Richard Browner and Andrew Boorn went so far as to call sample introduction "The Achilles’ Heel of Atomic ... read more

Quantitative bioanalysis is the most important application area of liquid chromatography coupled with atmospheric pressure ionization (API) tandem mass spectrometric detection (LC-API-MS-MS) in ... read more

In the biotechnology industry, traditional sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE)has been widely used to monitor the integrity and purity of therapeutic proteins during ... read more
