Assignee: UNIVERSITAT BASEL
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 9:
10. System (100) for preparing a sample on a support structure (20) comprising
a support structure (20) that is configured to accommodate a sample,
a temperature-controlled stage (1) that is configured to keep the support structure (20) at a pre-defined temperature when the support structure (20) is arranged on the temperature-controlled stage (1),
a transfer mechanism (60) that is configured to move the support structure (20) from the temperature-controlled stage (1) into a container (12) containing a liquid cryogen (80) so that the sample on the support structure (80) contacts the cryogen (80),, characterized in that the system (100) comprises
a light source (13) that is configured to provide light directed at the support structure (20),
a photodetector (14) that is configured to measure at least one intensity value of the light transmitted by the support structure (20),
a control device (30) that is configured to receive said measured intensity value from the photodetector (14) and trigger the transfer mechanism (60) dependent on the at least one measured intensity value, such that the support structure (20) is inserted into the container (12) containing the liquid cryogen (80).
