Analytical scientist

The analytical scientist often has to deal with large numbers of samples and one of the current interests is the development of methodology which allows these to be studied rapidly. One way of achieving this is to use a plate that can accommodate a number of samples, e.g. 96, each of which is confined within an individual hole ( well ) in the plate. With appropriate hardware, experimentation may be carried out simultaneously in each of these wells, thus dramatically increasing throughput of samples.

Various analytical methods have made quantum leaps in the last decade, not least on account of superior computing facilities which have revolutionised both data acquisition and data evaluation. Major developments have centred around mass spectrometry (as an ensemble of techniques), which now has become a staple tool in polymer/additive analysis, as illustrated in Chapters 6 and 7 and Section 8.5. The impact of mass spectrometry on polymer/additive analysis in 1990 was quite insignificant [100], but meanwhile this situation has changed completely. Initially, mass spectrometrists have driven the application of MS to polymer/additive analysis. With the recent, user-friendly mass spectrometers, additive specialists may do the job and run LC-PB-MS or LC-API-MS. The constant drive in industry to increase speed will undoubtedly continuously stimulate industrial analytical scientists to improve their mass-spectrometric methods. 

There are as yet no signs that the development of mass spectrometry is slowing down. This has consequences for the analyst. Whereas in the past the practitioner of polymer/additive analysis primarily benefited from a good knowledge of chromatography, it is now essential that such analytical scientists are conversant with current MS theory and practice. Advances in MS are due to new conceptual design, new ionisation methods (e.g. switched plasma sources) and...

It might be argued by some that this is overambitious. Can a student of archaeology with little if any recent formal training in the sciences really become a competent analytical scientist In our experience, the answer, overwhelmingly, is yes. Not, obviously, in the same sense as one who has had... 

The objective of this book is to provide both an overview and practical uses of the techniques available to analytical scientists involved in the development and application of methods for protein-based biopharmaceutical drugs. The emphasis is on considering the analytical method in terms of the stage of the development process and its appropriateness for the intended application. The availability of techniques will reveal whether or not the analytical problem has a potential solution. Then will come the question of whether or not the technique is a truly appropriate solution. The theoretical considerations behind choosing the technique may be solid. However, the practicality of the method may not hold up to inspection. 

Analytical scientists will provide support for many of the activities in a biopharmaceutical company. They are responsible for characterizing the molecules in development, establishing and performing assays that aid in optimization and reproducibility of the purification schemes, and optimizing conditions for fermentation or cell culture to include product yields. Some of the characterization techniques will eventually be used in quality control to establish purity, potency, and identity of the final formulation. The techniques described here should provide the beginning of a palette from which to develop analytical solutions.

At the same time, there are many effective chemometrics applications in PAT across a wide range of industries, although relatively few of them are published (for example, see references [15-19]). Nonetheless, these provide the driving force for analytical scientists and engineers to push for new applications in industry.

The discovery of semiconductor integrated circuits by Bardeen, Brattain, Shockley, Kilby, and Noyce was a revolution in the micro and nano worlds. The concept of miniaturization and integration has been exploited in many areas with remarkable achievements in computers and information technology. The utility of microchips was also realized by analytical scientists and has been used in chromatography and capillary electrophoresis. In 1990, Manz et al. [1] used microfluidic devices in separation science. Later on, other scientists also worked with these units for separation and identification of various compounds. A proliferation of papers has been reported since 1990 and today a good number of publications are available in the literature on NLC and NCE. We have searched the literature through analytical and chemical abstracts, Medline, Science Finder, and peer reviewed journals and found a few thousand papers on chips but we selected only those papers related to NLC and NCE techniques. Attempts have been made to record the development of microfluidic devices in separation science. The number of papers published in the last decade (1998-2007) is shown in Fig. 10.1, which clearly indicates rapid development in microfluidic devices as analytical tools. About 30 papers were published in 1998 that number has risen to 400 in... 

The objectives of formulation and analytical scientists are to develop new drug products for human use that are chemically and physically stable, bioavailable upon administration, manufacturable, cost-effective, elegant, and marketable.
