Description
Many years to decades can pass from the time when a new analytical method is for the first time demonstrated until the time of its widespread use for application experiments. For a successful transfer of knowledge and technology, this period must be marked by methodological development, proof-of-concept projects in different fields as well as training of people.
In the field of X-rays, the use of brilliant synchrotron radiation in many cases enables first unique experiments. A wide dissemination of the new method is often only reached, when laboratory equipment is available. At the Berlin Laboratory for innovative X-ray technologies (BLiX) we therefore develop since 2009 instruments and methodology for the laboratory scale. Successful examples are the transfer of confocal micro-X-ray fluorescence (XRF) spectroscopy to a commercial system1, the operation of a transmission X-ray microscope2 or the development of a soft X-ray absorption spectrometer (XAS) enabling transient measurements on thin films3 and liquids.
SyncLab, a joint research group between BLiX and the Berlin synchrotron BESSY II, now aims at exploring the use of both - laboratory and synchrotron setups. We demonstrate the added value of utilizing laboratory setups for XRF and XAS before and after beamtimes concerning training, sample preparation and statistical analysis. We discuss the merits both for users of the techniques as well as the general benefit for technology transfer and sustainable use of instrumentation.
