Abstract
There is provided a system (1) including a monitoring unit (50) that analyzes, using a sensor (51), components of a first gas which may include first components and a pre-separation unit (30) disposed upstream of the monitoring unit. The pre-separation unit includes: a first supply line (31) that supplies the first gas (35) to the monitoring unit; a second supply line (32) that supplies a second gas (36), which includes components obtained by removing the first components from the first gas using a first separator (40), to the monitoring unit; and an automatic valve station (38) that periodically switches between the first supply line and the second supply line to alternately supply the first gas and the second gas to the monitoring unit.

(canceled)
A lyophilization system comprising:
- a chamber that is configured to freeze dry a product;
- a vacuum unit that is configured to place the chamber at a negative pressure;
- a gas suppling unit that is configured to supply a gas for pressurization purposes to the chamber;
- a line that is configured to supply at least a part of exhaust gas from the chamber to a sensor for gas analyzing;
- and
- a system controller that is configured to measure an end point of freeze-drying process performed in the chamber by monitoring an amount of moisture in the exhaust gas using the sensor.
A control method of a lyophilization system that includes:
- a chamber for freeze drying a product;
- a vacuum unit for placing the chamber at a negative pressure;
- a gas suppling for supplying a gas for pressurization purposes to the chamber;
- a line for supplying at least a part of exhaust gas from the chamber to a sensor for gas analyzing;
- and
- a system controller,
- the control method comprising measuring, by the system controller, an end point of freeze-drying process performed in the chamber by monitoring an amount of moisture in the exhaust gas using the sensor.
A program product to be performed by a system controller of a lyophilization system that includes:
- a chamber for freeze drying a product;
- a vacuum unit for placing the chamber at a negative pressure;
- a gas suppling for supplying a gas for pressurization purposes to the chamber;
- and
- a line for supplying at least a part of exhaust gas from the chamber to a sensor for gas analyzing,
- the program product including a process of measuring an end point of freeze-drying process performed in the chamber by monitoring an amount of moisture in the exhaust gas using the sensor.
