Disclosed are systems and methods that include a thermal desorption unit, a chromatographic column, and an interface device between the unit and the column. For this purpose, according to the invention, the additional blind spot mirror is bonded onto the side of the substrate remote from the direction of light incidence on the substrate by a transparent, light-resistant adhesive. For further cells of the plurality of cells other than the first cell, a deviation information indicating a deviation of a numbering information of the respective further cell from the full numbering information of the first cell or one of the further cells is stored. In the milling process, the powder mixture may be treated to form FeS2 by heating the powder mixture or subjecting the powder mixture to a subsequent milling operation. Processing a test pattern before applying it on a tester provides a signature enabling a method for a tester to identify a scan cell which is stuck during the time the tester is operating on a device under test rather than accumulating voluminous test data sets for delayed offline analysis. An overlay of non-white second granules is adhered to the adhesive, such that the overlay of second granules and the adhesive provide a raised structure above a plane of the first granule coating.
