Analytical techniques


A Pfizer perspective

22 August 2005 | By Joep Timmermans, Ph.D., Senior Manager/Team Leader, Process Analytical Support Group – Americas Implementation Team, Pfizer Global Manufacturing

While the current attention and focus on Process Analytical Technologies (PAT) may make you believe otherwise, PAT measurement systems have been used in the pharmaceutical industry, Pfizer included, for some time, albeit often to a limited extent.

Efficient HTS in the nanoliter range

22 August 2005 | By Dr Johannes Ottl, Laboratory Head, Novartis Pharmaceuticals

The pharmaceutical industry continues to face an ever-changing, increasingly competitive business environment. This makes it imperative for drug discovery and development efforts to incorporate new technologies in order to reduce time-to-market to survive in today’s competitive marketplace. This industry pressure to shorten the R&D process has seen high-throughput screening (HTS)…

Integration of miniaturisation technologies

20 May 2005 | By Peter Hodder, Ph.D., Director & Head of Lead ID, Scripps Florida

In pharmaceutical drug discovery research, several technological advances have moved in vitro biological and biochemical experiments from the laboratory benchtop to fully automated high-throughput screening (HTS) robotic platforms1,2.

Getting a handle on neuronal behaviour in culture

20 May 2005 | By Peter B. Simpson, Senior Research Fellow – Automated imaging, Neuroscience Research Centre, Merck Sharp and Dohme

In drug discovery for CNS diseases, the use of complex neural cell culture systems offers many advantages. Innovations in high content screening enable us to identify compounds which affect key cell biological properties in such cultures. We can bridge the divide between kinetic and endpoint screening by use of another…

Exploring new sources of raw material

20 May 2005 | By Bernhard Schrader, Institut für Physikalische und Theoretische Chemie, Universität Duisburg-Essen and Hartwig Schulz, Federal Centre for Breeding Research on Cultivated Plants, Institute of Plant Analysis

Raman spectroscopy using excitation in the near infrared allows non-destructive Raman analyses of pharmaceutical products as well as of plant or animal tissues. This radiation excites only minimal fluorescence of the samples or impurities and has only minimal photo-physical and photochemical activity. Raman analysis of plants allows the efficient exploration…

Harbinger of change

20 May 2005 | By Ali Afnan, Ph.D., Process Analytical Technologist, FDA/CDER/OPS

The pharmaceutical industry plays a major role in the lives of individuals by providing critical therapeutic medicines. This places the industry in the public eye, as does drug pricing, safety and efficacy, the stock markets and courting with several different regulatory bodies, with differing legal requirements, around the world. The…

New phases for rapid ion analysis

7 March 2005 | By Dr Brett Paull and Prof. Pavel Nesterenko, Research Scientists, National Centre for Sensor Research, Dublin

Ion chromatography (IC) is currently used throughout chemical and pharmaceutical industries for the quantitative determination of inorganic and organic anions and cations in a variety of matrices from both raw materials to finished products. In most cases, suppressed IC is utilised, particularly for the determination of inorganic anions and this…

A process analytical tool

7 March 2005 | By Jukka Rantanen, Senior Research Scientist, Viikki Drug Discovery Technology Centre, University of Helsinki

There is an increasing demand for new approaches to understand the chemical and physical phenomena that occur during pharmaceutical unit operations. Obtaining real-time information from processes opens new perspectives for safer manufacture of pharmaceuticals. Raman spectroscopy provides a molecular level insight into processing and it is therefore a promising process…

Versatile miniaturised HTS

7 March 2005 | By Oliver Bruttger, Danielle Folio, Christine Niklaus and Johannes Ottl, Novartis Institute for BioMedical Research, Lead Discovery Center Basel

Research and development for a pharmaceutical company is a difficult and lengthy process. It stretches from the discovery phase to preclinical and clinical development stage, through the drug approval period ultimately to clinical application. The discovery research phase is one of the early key processes. The research starts with target…


7 March 2005 | By Dirk C. Hinz, Ph.D., Schering AG, Corporate CMC Development, In-Process Control Dept.

Pharmaceutical manufacturing occurs in a highly regulated environment, where most of the manufacturing is performed in batches, in stop-and-go steps and with off-line testing of product quality. Additionally, due to patent restrictions, there is always ‘speed to market’ pressure.
