• an outflow liquid receiver that is provided with a partition provided between the outflow liquid receiver and the liquid waste receiver, and is used to receive a liquid waste that has flowed over the partition to flow out from the liquid waste receiver;
• and
• a liquid sensor that is provided in the outflow liquid receiver and is used to detect a liquid waste that has flowed out from the liquid waste receiver,
• wherein
• the outflow liquid receiver is configured to receive a leak liquid in the analyzer prior to any overflow of the leak liquid over the partition into the liquid waste receiver, and the leak liquid is detected by the liquid sensor or a separately provided second liquid sensor prior to the any overflow of the leak liquid over the partition.
