Analysis device and method for determining an oscillation pattern of a substance

An analysis device for determining an oscillation pattern of a substance, comprising:

• a central unit with two identical sample containers, two microphone apparatuses, a differential amplifier, opaque closing lids, connecting lines and oscillation-damping elements;
• wherein the sample containers are closable by the respective opaque closing lids, wherein the interior of the sample containers is shielded by walls of the sample containers and the closing lids from all sides from optical radiation after closing;
• wherein one of the microphone apparatuses is respectively arranged in the respective sample containers;
• wherein the microphone apparatuses are electronically coupled to the differential amplifier via the respective connecting lines, wherein the connecting lines are each identically constructed;
• wherein the differential amplifier is formed to compensate for in-phase parasitic oscillations from both sample containers and to determine the oscillation pattern of the substance upon introduction of the substance into only one of the two sample containers;
• and
• wherein the analysis device does not comprise an excitation source, by which the sample containers and/or the substance are excitable in one of the two sample containers;
• wherein the two sample containers are mounted by the oscillation-damping elements, which are formed to absorb and reduce oscillations,
• wherein the central unit is formed as a Faraday cage;
• and
• wherein the analysis device comprises a sound-absorbing housing, wherein the central unit is arranged in the sound-absorbing housing.
