Precision needle tips for liquid handling systems

Sampling needles and dispensing probes are a vital part of any liquid handling system.

Software-controlled microscopy

Software-controlled microscopy is the catchphrase. New technologies and the opportunities offered by them have changed the way people work at the microscope and the entire world of the laboratory. Dr Manfred Kässens reports.

Purification of Plasmid DNA by polishing and Endotoxin removal

Increasing requirements for higher purity plasmid DNA preparations have driven the development of new chromatography technologies. Victor Bornsztejn reports.

Enabling confocal microscopy

Weighing launches

Ohaus Corporation's new Pro Series balances comprises three Adventurer Pro, Explorer Pro and Scout Pro

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.

ICP-OES allows for sensitive analysis of organic samples

Dirk Ardelt, George Glavin, Sergej Leikin and Henk Visser look at the use of inductively coupled plasma-optical emission spectroscopy and the potential difficulties in its use in analysing organic samples.

"Modular HPLC system offers flexibility, reliability and sensitivity"

Users of HPLC instrumentation require a vast array of features and working specifications to meet their application requirement.

Ultra-thin-layer chromatography plates

The new era of chromatographic separation started with Chromolith HPLC columns. Now Merck's latest innovation in monolithic silica technology is the ultra-thin-layer chromatography plates (UTLC).

Enhancing productivity in preparative separation of enantiomers

The separation of enantiomers by chromatography is a field expanding significantly due to the increasing interest for pure enantiomers in the pharmaceutical industry.

Spectrophotometers increase in sophistication and reliability

Over recent years, UV/Visible spectrophotometry has also become even more popular in application areas such as molecular biology. This popularity is partly due to the simplicity of analysis, the non-destructive nature of the sampling, and...

Sequential isolation of plasma proteins aids immunoglobulin yields

The demand for immunoglobulin is high and is predicted to rise. John Curling reports that current goals are to improve yield of immunoglobulin while maintaining product quality.

Beamforming breakthrough boosts accuracy of ultrasonic technology

Focusing the sound waves used in ultrasound devices has always posed a number of technical challenges. However, a new innovation from Germany that gives greater control over the sound waves could lead to far more accurate ultrasound-based...

chromatography data system

Autoscribe Ltd's Varian Galaxie chromatography data system is now available. Galaxie is fully scalable from single chromatograph workstations to global implementations with an easy upgrade path.

Sound out ultrasonic spectroscopy in the pharmaceutical processes

In the last issue of Elab, the principles behind ultrasonic spectroscopy were introduced. Here, Cormac Smyth,Evgeny Kudriashov, Breda O'Driscoll and Vitaly Buckintake a closer look at its practical applications.

Microbial resistance drives search for new products

The rise and rise of microbial resistance to currently available antibiotics is driving the development of new generation anti-infective products. John Carter reports.

New references assist validation in far ultra violet spectroscopy

John P Hammond reports on new certified reference materials for the determination of wavelength and photometric accuracy in far UV spectrophotometry.

Affinity chromatography is vital to protein research and development

Because they are derived from living organisms, biological products present a potential source of pathogens. By John M. Curling.

system integration reduces costs

Whoever wants to maintain their competitive capacity today has to consider the complete flow of processes in the company, organising the areas adevelop-make-sell' as efficiently as possible.
