Organic/inorganic solution for HPLC separation problems

High-efficiency silica-based packings have been used in high performance liquid chromatography (HPLC) since 1973. Over the past 27 years, says Sylvie Mamon, many improvements have been made to the technology of these packings.



Streamlining purchasing with a global e-procurement solution

When one of the world's major pharmaceutical companies decides to streamline its enterprise-wide purchasing processes, it needs a solution that is rich in product data, requisition consolidation, reporting and catalogue management, and one that is capable of integration with other enterprise software systems.



Single tube solution streamlines the extraction of nucleic acid

The polymerase chain reaction (PCR) has changed the way we do life sciences, but the impact of this technology has reached far beyond that, into clinical settings and other fields of study such as gene/drug discovery, forensic science, ecology, archaeology, genetics/molecular biology, and anthropology. Craig M Sampson reports.



Novel solution for particle size measurement problems

Work undertaken in Germany is demonstrating how a new particle size measurement technique is opening up many new applications areas in the laboratory. Heike Krischollek reports on the specific problems posed when dealing with biological materials and how one new measurement system has been designed to overcome these difficulties.
