Detection of GM

Due to the increased use of genetic modifications in crop improvement, there is a need to develop effective methods for the detection of both known and unknown transgene constructs in plants.

Lasers disease detection

By blasting a person's breath with laser light, scientists have shown that they can detect molecules that may be markers for diseases like asthma or cancer.

Pressure devices now have non-invasive sensor detection as standard

Elfab, one of Europe’s leading suppliers of pressure-relief systems, has added detection to each of its main product lines, giving end-users an immediate indication that a bursting device has operated.

LC/MS detection: powerful tool for organic compound analysis

Diab Elmashni outlines the advantages of liquid chromatography coupled with mass spectrometry detection.

Detection of foreign yeast cultures in Yoghurt

Sensor Array instrumentation is already well known as aelectronic nose technology'.

New medium for the detection of Vibro cholerae

Oxoid Limited has extended the Oxoid range of products for the growth, isolation and identification of Vibrio cholerae and other Vibrio species to include Alkaline Peptone Water (CM1028).

Faster detection of enterobacter sakazakii in infant formula

With increasing concern about the occurrence of Enterobacter sakazakii infections in neonates who have been fed milk-based powdered infant formula, new Oxoid Chromogenic Enterobacter sakazakii Agar (Druggan-Forsythe-Iversen formulation) provides a valuable tool for food testing laboratories.

Digital multimodal imaging for biomarker detection

Darlene Wood reports on the use of charged-coupled device imaging systems in life science research imaging applications.

Culture media for the detection of coliforms/E.coli

Merck has developed culture media for the detection of coliforms/E.coli for matching two different application areas: potable water/processed food or waste water/fresh food. Now you have a choice: Chromocult Coliform Agar and Coliform Agar ES (enhanced selectivity).

The benefits of using evaporative light scattering detection in HPLC

Evaporative light scattering detection (ELSD) has become widely used in the field of HPLC. For non-UV absorbing compounds, ELSD is a primary choice since the principle of detection does not rely on the optical properties of the solute.

Rapid test for the detection of listeria

The range of Merck's rapid tests of the lateral flow type has now been completed. With Singlepath Listeria you can exclude the presence of listeria within 20 minutes after enrichment. For you this can mean a head start of two days in bringing your products to market without making concessions as regards safety standards.

Improved detection limits withX-ray fluorescence spectrometer

Dirk Wissman looks at the monitoring of limits for heavy metaltraces in pharmaceutical products using an energy-dispersiveX-ray fluorescence spectrometer.

Detection refined as genomic and proteomics investigations advance

From Dutch researchers who are combining surface plasmon resonance imaging with microfluidics to large companies pioneering ultra fast genetic analysis techniques, efforts to understand what DNA does at a molecular level have never been more intense.

Evaporative light scattering detection: indicator of a mass response in LC work

Evaporative light scattering detection (ELSD) has become well established in the field of liquid chromatography (LC), writes Jeanie Watkins.

Detection systems for GMO crops

Kimball Nill reports on interference by soil-borne bacteria and micro-organisms when using PCR-based detection methods.

Detection and quantitation of nitrosylated proteins

Rajesh Manchanda and Frederick A Liberatore look at the uses of nitric oxide biochemistry in cell signalling and cell death.

Achieving lower detection limits of volatile nitrosamines in tobacco

Eric Phillips and Mary Dennis discuss the use of triple quadrupole GC-MS/MS as a potential solution for accurate detection, measurement and analysis of VNAs in tobacco
