Abstract: A system (1) for measuring the optical activity of a sample (2) comprises at least one frequency modulation device (3), at least one synchronization device (4), and at least one detection device (5). The frequency modulation device (3) is configured to modulate a frequency of incident electromagnetic radiation being emitted from a sample (2) and/or being irradiated on to a sample (2) with at least one frequency modulation signal (Sf). The synchronization device (4) is configured to receive the at least one frequency modulation signal (Sf) and to emit at least one detection modulation signal (Sd) being synchronized with the at least one frequency modulation signal (Sf). The system (1) is configured such that the detection device (5) detects the electromagnetic radiation (EMs) in synchronization with the detection modulation signal (Sd).

Abstract: The present invention relates to a clearing link connecting a plurality of clearing houses for clearing and settling transactions stemming form a trading platform. The clearing link processes transaction data stemming from the trading platform to be forwarded to individual clearing houses. The clearing house(s) are selected based on a transaction data analysis and predefined forward conditions. A trade member is thus able to select a clearing house not directly linked to the market of the trade member.
