The invention relates to a high-pass branch of a frequency separating filter for ADSL systems comprising inductive components which dispose of magnet cores made of a soft magnetic amorphous or nanocrystalline. The first substrate layer overlies the second substrate layer to define a volume therebetween configured to receive a wearer’s hand. Upon analysis, a solation agent is added to the non-fluid substance medium to increase the fluidity of the non-fluid substance, thereby the particles bearing the anti-analyte can diffuse in the medium to cause the agglutination with the analyte.
