Electrophoresis has been around for most of the last century, but only during the past decade has the technology expanded its throughput capabilities. Traditional systems had sample throughout capacities that ranged from as little as four to as many as 16 wells/combs. However, with the new breed of higher-throughput systems, these capabilities have increased to […]

The promise of MS revolutionizing the clinical diagnostics market has been discussed for years, but MS has only experienced limited commercial success in the market. MALDI-TOF is one of several MS techniques that is now making inroads into clinical diagnostics labs but is far from achieving its potential in the area. While technological hurdles are […]

While they are both based on similar physical principles, atomic fluorescence spectroscopy (AFS) is far less common a technique than atomic absorption spectroscopy (AA). Both provide elemental composition information and rely on the specific wavelengths of light that serve to identify particular elements corresponding to the lines in their atomic spectra. In both, the sample […]

Luminex’s xMAP suspension bead array systems have been widely adopted for research, drug discovery and IVD applications. The xMAP technology uses microscopic polystyrene beads as a carrier of a specific protein, antibody or nucleic acid. These beads are internally dyed using precise ratios of fluorophores, allowing researchers to detect specific reactions. Luminex offers three systems […]

Portable and handheld NIR have rapidly developed into a major analytical instrument market alongside other portable spectroscopy techniques, all of which have benefited from similar technological improvements. The portable NIR market has transitioned into a much more mature market in recent years with the acquisition of smaller start-ups that pioneered the market by major diversified […]

Rapid DNA analysis is a new technology designed to identify DNA samples in 90 minutes or less. The traditional method of performing DNA analysis involves several different platforms: sample preparation by extraction; amplification by PCR; separation, oftentimes by capillary electrophoresis (CE); and DNA identification by UV absorbance or fluorescence. This process generally takes over 10 […]

Hydrophilic interaction chromatography (HILIC) is a variation of normal-phase LC. It has a similar elution profile to normal-phase chemistry in that analytes elute in the order of increasing polarity. However, the difference is that normal-phase methods use an entirely organic solvent mixture, while HILIC employs an aqueous-organic solvent blend. HILIC HPLC columns are typically packed […]
