An elliptical satellite system which carries out communication. The synthesis method and the use as a fluorescent marker are for inorganic solid supports, for example silica nanoparticles, andor for biomolecules such as peptides, antibodies, DNA, RNA, etc. The coil bracket is also able to be removed from the base member. For example, the method can be used to optimize analytical systems including an ion mobility spectrometer that uses a temperature stepped desorption technique for the detection of explosive mixtures. A set of observed signal parameters is determined, the set comprising at least one signal parameter for each of several channels at the receiver’s location.
