Product Round-up
Although a mature product category, microplate readers are evolving towards greater functionality, flexibility, and throughput. All top instrument makers are focusing at least some efforts on multiplexing. “Vendors are introducing evolution

Within a decade of its discovery in 1983, polymerase chain reaction (PCR) evolved into one of biology’s most useful tools. PCR amplifies specific segments of genes so accurately that an early National Institutes of Health publication dubbed the

RNA interference (RNAi) uses short strands of synthetic ribonucleic acid (RNA) to silence or “knock down” genes implicated in certain phenotypes—most commonly (but not limited to) diseases.

Chromatographers who learned their craft twenty years ago may not have been familiar with autosamplers then, but today nearly every high performance liquid chromatography (HPLC) instrument includes an autosampler as standard equipment. “Aut

Gas chromatography-mass spectrometry (GC-MS) is the fastestgrowing GC method. Mass detection, which can take a variety of forms based on the MS component, provides a dimension that conventional thermal conductivity or flame ionization detectors canno

GC was once commonly called “GLC,” where the “L” stands for liquid. Inside GC columns are particles of a ceramic or inert material coated with a viscous liquid stationary phase that interacts with the analyte. By contrast, HPL

Although serious Fourier-transform infrared spectroscopy (FTIR) research and core analysis facilities are still doing well, traditional applications are giving way to more dynamic uses such as controlling processes and field work. For research FT

Atomic absorption (AA) has been known since the 19th century, but it was not until the 1950s, thanks to efforts by Alan Walsh at Australia’s CSIRO research center, that use of AA spectrometers became routine for metals analysis. AA measures

Common in both industrial and academic laboratories, mixing is an important part of many tasks. Deciding which type of stirrer, magnetic or overhead, is best for you depends on the viscosity and scale of the substance you’re stirring.
