Automated Quantitative Analysis of Ethanol, Glucose and NADH in the UV/VIS and Short NIR

Process Analytical Technology currently becomes more and more important for food and pharmaceutical industry for example because of the increasing demand for more effective and efficient quality control. Therefore it is necessary to get timely and targeted responses of the different parameters in bioprocesses. To attain this aim, it is helpful to replace the conventional (manual) laboratory techniques with automated measuring processes via in-line probe.

Microfluidic analysis of amino acids using aminoacyl-tRNA synthetase coupled with spectrophotometric detection

Analyses of free amino acids in biological fluids?—?such as urine and plasma?—?can be useful in determining disease status in clinical diagnoses [1]. In the food industry, unique changes in amino acid concentrations are useful markers of freshness, nutrition, and taste.

Validation of an Automated Cell-Based Bioluminescent TNFa Blocker Bioassay
Brad Larson, Tracy Worzella, Rich Moravec, Neal Cosby, Frank Fan, Teresa Surowy and Peter Banks

TNFa blocker biopharmaceuticals represent an important and successful class of protein drugs used in the treatment of several autoimmune diseases. Bioassays are indispensible tools in biopharmaceutical drug development and commercialization that are used to quantify biological activity and stability of drugs or drug candidates. The automation of these assays can serve to create an accurate, robust process which can allow the researcher to perform other more important functions.

Ensuring the Quality of Registered Compounds in a Drug Discovery Environment – A Multidisciplinary Approach
Ryan Sasaki and Tara Sinclair

Lexicon Pharmaceuticals have demonstrated that a practical automated verification system using HPLC, LC/MS, and 1D and 2D NMR can be implemented in an industrial/pharmaceutical environment. This system has proven to be robust, and provides added value to compound collection integrity and quality.

A Self-Monitoring Quality Management System Incorporating Spectral and Chromatographic Data
David Snyderman, Colin Read and Tara Sinclair

LIMS are useful in managing certain types of data for quality management and sample tracking. However, these systems are generally limited in the types of information they can process and store. A unique automated quality management system has been developed and implemented at a fragrance manufacturer to evaluate chromatographic and spectral data of samples during quality testing.

Characterizing a Nasal Spray Formulation from Droplet to API Particle size
D Huck, P Kippax, A Virden and Carl Levoguer

Interaction of a nasal spray product with the patients’ body depends on key variables such as the particle size of the delivered droplets and the suspended active pharmaceutical ingredient (API). The particle size of the drug can be an important parameter for the rate of dissolution and availability to sites of action within the nose.
