✦ Synopsis

A national comparison of high dc resistance at 10 MX and 1 GX level was organized by the Electromagnetic Division of National Institute of Metrological Research (INRIM, Italy) and piloted by the high dc resistance Laboratory of the same Division. This comparison took place between January and April 2008 with the participation of 8 Secondary Laboratories accredited by the Italian Service of Accreditation of Calibration Laboratories (SIT). The travelling package included one wire-wound 10 MX standard and one thick film-type 1 GX standard in a wooden anti-shock container designed by INRIM. The obtained results indicate that the relative differences at 10 MX and 1 GX between each Laboratory's value and the respective reference value are all within the expanded relative uncertainties of these differences at a 2r confidence level.

## Abstract A sophisticated matching algorithm developed for highly efficient identity search within tandem mass spectral libraries is presented. For the optimization of the search procedure a collection of 410 tandem mass spectra corresponding to 22 compounds was used. The spectra were acquired in

Mass spectral libraries represent versatile tools for the identification of small bioorganic molecules. Libraries based on electron impact spectra are rated robust and transferable. Tandem mass spectral libraries are often considered to work properly only on the instrument that has been used to buil
