Reagent preparing apparatus and sample analyzer

A sample analyzer comprising:

• a reagent preparing section for preparing a diluted reagent containing a predetermined reagent and pure water;
• a sample measuring section, connected to the reagent preparing section, for measuring a sample using the diluted reagent prepared by the reagent preparing section;
• a pH measuring section for measuring hydrogen ion concentration of the diluted reagent prepared by the reagent preparing section;
• and
• a controller for performing predetermined processing, wherein the controller is configured to change the process to be performed based on the hydrogen ion concentration measured by the pH measuring section.

A reagent preparing apparatus capable of being connected to a sample measuring section for measuring a sample using a diluted reagent prepared by the reagent preparing apparatus, comprising:

• a reagent preparing section for preparing a diluted reagent containing a predetermined reagent and pure water;
• a pH obtainer for obtaining hydrogen ion concentration of the pure water before being used to prepare the diluted reagent;
• and
• a controller for performing predetermined processing, wherein the controller is configured to change the process to be performed based on the hydrogen ion concentration obtained by the pH obtainer.
