Abstract

The Astronomical Institute of the University of Berne is hosting one of the Analysis Centers (AC) of the International GPS Service (IGS). A network of a few GPS stations in Europe and North America is routinely analyzed for time transfer purposes, using the carrier phase observations. This work is done in the framework of a joint project with the Swiss Federal Office of Metrology and Accreditation (METAS). The daily solutions are computed independently. The resulting time transfer series show jumps of up to 1 ns at the day boundaries. A method to concatenate the daily time transfer solutions to a continuous series was developed. A continuous time series is available for a time span of more than 4 mo. The results were compared with the time transfer results from other techniques such as two-way satellite time and frequency transfer. This concatenation improves the results obtained in a daily computing scheme because a continuous time series better reflects the characteristics of continuously working clocks.

Prediction of gas chromatographic retention indices of a diverse set of toxicologically relevant compounds.

For a set of 846 organic compounds, relevant in forensic analytical chemistry, with highly diverse chemical structures, the gas chromatographic Kovats retention indices have been quantitatively modeled by using a large set of molecular descriptors generated by software Dragon. Best and very similar performances for prediction have been obtained by a partial least squares regression (PLS) model using all considered 529 descriptors, and a multiple linear regression (MLR) model using only 15 descriptors obtained by a stepwise feature selection. The standard deviations of the prediction errors (SEP), were estimated in four experiments with differently distributed training and prediction sets. For the best models SEP is about 80 retention index units, corresponding to 2.1-7.2% of the covered retention index interval of 1110-3870. The molecular properties known to be relevant for GC retention data, such as molecular size, branching and polar functional groups are well covered by the selected 15 descriptors. The developed models support the identification of substances in forensic analytical work by GC-MS in cases the retention data for candidate structures are not available.

Size-exclusion chromatography-a review of calibration methodologies.

Recent developments are reviewed in size exclusion chromatographic calibration methodologies, including direct calibration by using narrow and broad polymer standards and various instrumental methods (nuclear magnetic resonance, mass spectrometry, light scattering) as well as universal calibration with and without viscometry detectors, for simple and complex polymers.

A mini-rapid-scan-spectrophotometer.

The mini-rapid-scan-spectrophotometer (Mini-RSS) is a scanning single-beam spectrophotometer that has been patented. It is based on a minimum of reflections and involves exclusively mirrors as beam-deflecting components. This way stray light is minimized, which results in an excellent light-throughput, high dynamics, low cost, compactness and rigidity. The Mini-RSS has been designed as a multi-purpose instrument that allows absorption, transmission, reflection, fluorescence and luminescence measurements in a single-beam mode. Its spectral range extends from the UV and visible spectrum to the IR. This provides for the possibility to measure even optically unfavorable, highly turbid or scattering samples that would be otherwise inaccessible to investigations with commercial spectrophotometers. A miniaturized and very sensitive photomultiplier-module (PM) of high dynamics allows in the visible spectral range absorbance measurements that cover up to four OD units. The Mini-RSS is capable of scanning up to 100 spectra per second with a resolution of 12 bit and 500 points. The linear dispersion is currently 5 nm and the stray light level <0.01%.
