Three modes of sample application on the chromatographic plate are applied at present investigations of pressurized planar electrochromatography (PPEC) systems taking into special attention their influence on performance of the separating system. These modes are as follows: application of the sample solution directly on the chromatographic plate with microsyringe, deposition of sample solution on...
Europe is a region with the largest density of geomagnetic observatories and several authors have used these data to estimate local geomagnetic response functions for various period ranges, typically of the width of 1.5 to 2.5 decades. By collecting the local response functions from 35 European observatories, and by their precise selection and subsequent combination, the independent regional geomagnetic...
