Abstract
A pH management system of a liquid chromatograph includes a pH meter that measures a pH value of a mobile phase in the liquid chromatograph, and a warner that presents a warning in a case where it is determined that a pH value measured in the pH meter is different from a set pH value, or that the pH value measured in the pH meter deviates from the set pH value and an error rate exceeds a predetermined error rate, when the pH value measured in the pH meter and the set pH are compared to each other.
Claims10
A pH management system of a liquid chromatograph comprising:
- a pH meter that measures a pH value of a mobile phase in the liquid chromatograph;
- and
- a warner that presents a warning in a case where it is determined that a pH value measured in the pH meter is different from a set pH value, or that the pH value measured in the pH meter deviates from the set pH value and an error rate exceeds a predetermined error rate, when the pH value measured in the pH meter and the set pH are compared to each other.
A pH management system of a liquid chromatograph comprising:
- a pH meter that measures a pH value of a mobile phase in the liquid chromatograph;
- and
- a pH saver that saves a pH value measured in the pH meter in association with a result of an analysis performed in the liquid chromatograph.
A computer readable recording medium recording a pH management program of a liquid chromatograph that causes a computer to execute the processes of:
- inputting a pH value of a mobile phase measured in a pH meter in the liquid chromatograph;
- determining whether a pH value measured in the pH meter is different from a set pH value, or whether the pH value measured in the pH meter deviates from the set pH value and an error rate exceeds a predetermined error rate;
- and
- presenting a warning in a case where it is determined that a measured pH value is different from the set pH value, or that the measured pH value deviates from the set pH value and an error rate exceeds a predetermined error rate.
A computer readable recording medium recording a pH management program of a liquid chromatograph that causes a computer to execute the processes of:
- inputting a pH value of a mobile phase measured in a pH meter in the liquid chromatograph;
- and
- saving an input pH value in association with a result of an analysis performed in the liquid chromatograph.
