A computer program for automated data evaluation to support in vitro higher-throughput screening for drug metabolism and pharmacokinetics attributes

With the advances in analytical techniques, higher-throughput screening for drug metabolism and pharmacokinetics (DMPK) attributes has become an integral part of drug discovery. However, as the number of compounds increases, the volume of data that needs to be processed and evaluated increases exponentially. As a result, a major challenge for the analytical chemist is how to quickly process the vast amount of data so as to keep up with the throughput of the screening assay. We have developed a customized computer program for automated evaluation of the liquid chromatography/tandem mass spectrometric (LC/MS/MS) data generated from the in vitro DMPK screening assays. This program performs automatic data processing and quality control. It identifies analytical anomalies, such as low internal standard intensity and poor reproducibility of replicates. All analytical anomalies for individual compounds are summarized into an 'E-Log' in a color-coded format for reviewing. With the use of this program and other supporting software, data processing and evaluation for up to 100 compounds are accomplished in several minutes.

Brevion: the new small-scale industrial gamma irradiator

The economical processing of low-volume products has been a challenge to the gamma industry since inception, influencing customers to send their products to contractors or choose alternative technologies. With the introduction of the Brevion irradiator (patent pending), economical gamma processing of low annual volume product lines is now possible. This innovative design is specifically targeted at plants processing product volumes of up to 20,000 m³/yr. Brevion provides good cobalt efficiency and good dose uniformity, thus processing these volumes efficiently and economically. The Brevion facility has the distinct advantage of a low capital cost, compared to medium-sized automatic tote plants, while maintaining similar performance. Lead-time for the construction phase is also considerably shorter, resulting in significantly lower start-up costs. Companies with low-volume product lines can now achieve the control provided by in-house processing, and eliminate transportation time and costs associated with shipping products off-site.

Summary The different steps of automation of an HPLC system are discussed. With automatic sample injection, a higher through put and a better reproducibility can be achieved than with manual injection.Peak processing systems are necessary to manage the flood of data. Post run optimization of the integration parameters are possible with a computer system. Data systems provide an enormous flexibility to produce different kinds of reports, summaries and graphs and to perform statistical calculations.The assay and purity control of a peptide hormone injection (Lys⁸-Vasopressin) is shown as an example of automated HPLC.

Benefits and pitfalls of the application of screening methods for the analysis of pesticide residues in fruits and vegetables

The goal of this study was to expand knowledge on the performance of screening methods based on accurate mass measurements using a liquid chromatography electrospray quadrupole time-of-flight mass spectrometry (LC-ESI-QTOF-MS) system operating in full scan mode and with automatic identification based on the use accurate-mass databases. The study involved the analysis of 97 pesticides, in five matrices (tomato, pepper, zucchini, orange and leek) and at three concentration levels (20, 50 and 100 μg kg(-1)). Aspects concerning optimization of the search parameters, sensitivity, matrix effects, efficiency of the algorithm search, usefulness of fragment ions, etc., are evaluated in deep. Sensitivity requirements have been identified as the main obstacle affecting the automatic identification of pesticides, especially in complex matrices, where the ionization suppression reduces the detectability of analytes. In addition, we have detected some failures in the software used for automatic data processing in terms of analysis of isobaric compounds, use of isotopic clusters, spectral deconvolution and data processing speed that hamper the correct identification in some pesticide/matrix combinations. These drawbacks should be improved in the future for its effective implementation in routine residue analysis.

Summary The International Data Centre of the Comprehensive Nuclear-Test-Ban Treaty Organisation receives atmospheric radioactivity data from the monitoring stations of the International Monitoring System. The Centre is a processing hub through which raw data and analysis results flow to Treaty Member States. Data are processed automatically upon receipt, and then interactively reviewed and screened for detection of CTBT-relevant radionuclides. Atmospheric back-tracking for source location is included in the IDC functions. This paper describes the role of the IDC in this verification effort, the types of radionuclide monitoring data received, the automatic and interactive processing, and the products distributed to Member States.
