Title:
容器内の溶液の再構成が完了したか否かを判定する方法
Document Type and Number:
Japanese Patent JP6648042
Kind Code:
B2
Abstract:
A method for determining whether reconstitution of a solution (6) in a container (1) is completed comprises the steps of:
- selecting a predetermined amount of a solid substance (2) and a predetermined amount of a liquid solvent (5) from which the reconstituted solution (6) is to be prepared,
- preparing a solution (6) by solving the predetermined amount of the solid substance (2) in the predetermined amount of the liquid solvent (5),
- measuring the impedance (Z) or the resistance (R) of the solution (6),
- determining whether the change of the measured impedance (Z) or the resistance (R) within a measuring time interval of a predetermined duration is below a defined threshold, and
- determining that reconstitution of the solution (6) is completed when the change of the measured impedance (Z) is below the defined threshold.
