When monitoring the state of a chromatography apparatus, a plurality of states establishing a single monitoring condition are considered, and generally the state of a chromatography apparatus cannot be specified only by establishing a single monitoring condition. In such a case, it is necessary for the user to combine a plurality of single monitoring conditions to specify the state of the chromatography apparatus. Conventionally, the user grasps such a combination to specify the state of the chromatography apparatus. However, in such a case, when the combination of monitoring conditions becomes complex, it is difficult to grasp the details.

SUMMARY

One or more embodiments provide a monitoring method, a monitoring device, and a monitoring system for monitoring a state of a chromatography apparatus wherein details of the monitoring conditions can be easily grasped, even when combining a plurality of monitoring conditions.

A monitoring program according to several embodiments is a monitoring program for monitoring the state of a chromatography apparatus, including: an input step for receiving input of a single monitoring condition including determination conditions for parameters relating to the measurements taken using the chromatography apparatus, or input of combined monitoring conditions combining a plurality of the single monitoring conditions; and a display step for displaying in parallel a first conditional expression based on at least one of the single monitoring conditions, constituting a portion of a first combined conditional expression based on a first combined monitoring condition combining all inputted monitoring conditions, and a second conditional expression based on at least one of the single monitoring conditions, associated with the first conditional expression by a combination operational expression. Thus, even if the user does not grasp the combination of measurement data necessary for estimation, the user can easily identify the state of the chromatography apparatus. In other words, even when combining a plurality of monitoring conditions, the user can easily grasp the details of the monitoring conditions, and user convenience improves.

The monitoring program according to one or more embodiments may further include a determination step for determining the first combined conditional expression based on the first combined monitoring conditions combining all inputted monitoring conditions. Thus, the user can, for example input only a simple single monitoring condition, without inputting a complex first combined monitoring condition. Therefore, input settings of the monitoring conditions are simplified, and user convenience improves.

The monitoring program of one or more embodiments may display, in the display step, two portions of the first combined conditional expressions in two columns respectively and arrange the first conditional expression and the second conditional expression in the same row, the first and second conditional expression being mutually associated by the combined operation expression. Thus, even with a small screen and a limited display region and the like, it is possible to provide a display wherein the user can easily grasp the conditional expression. In other words, user visibility improves.

The monitoring program according to one or more embodiments may, in the input step, receive input of comments relating to the second combined monitoring conditions based on the second combined expression configured by the first conditional expression, the combined operational expression, and the second conditional expression, and further display the comment arranged in the same row as the first conditional expression and the second conditional expression in the display step. Thus, the user can easily grasp the effect of the combined monitoring conditions of column degradation and the like. Furthermore, even if there is no abnormality in a column, the user can grasp the state of other positions and the possibility of an abnormality appearing in those positions. Grasping these enables the user to rapidly perform accurate maintenance work.

The monitoring program according to one or more embodiments may further include a receiving step for receiving information of parameters relating to the measurements taken using the chromatography apparatus from the chromatography apparatus; a determining step to determine at least one of whether a second combined monitoring condition based on the second combined conditional expression configured by the first conditional expression, the combined operational expression, and the second conditional expression based on information of parameters relating to the received measurements is established, and whether the first combined monitoring condition is established; and a notification step to notify that corresponding conditions are established based on the established determination of the determining step. Thus, making a determination using combined monitoring conditions combining a plurality of single monitoring conditions enables monitoring of the state of a chromatography apparatus that could not be grasped by only a single monitoring condition. Furthermore, a notification from the notification step enables the user to more intuitively grasp whether each conditional expression is established.

For the monitoring program of one or more embodiments, the parameters relating to the measurements taken using the chromatography apparatus may include: an operation parameter of each constituent part that configures the measurement system for measurements taken using a process gas chromatography apparatus; and an analysis parameter for measurement results obtained by measurements taken using the process gas chromatography apparatus.

The monitoring device according to one or more embodiments is a monitoring device for monitoring the state of a chromatography apparatus, provided with: a control part; an input part for receiving input of a single monitoring condition including determination conditions for parameters relating to measurements taken using the chromatography apparatus, or input from combined monitoring conditions combining a plurality of the single monitoring conditions, and a display part for displaying in parallel a first conditional expression based on at least one of the single monitoring conditions, constituting a portion of a first combined conditional expression based on a first combined monitoring condition combining all inputted monitoring conditions, and a second conditional expression based on at least one of the single monitoring conditions, associated with the first conditional expression by a combination operational expression. Thus, even if the user does not grasp the combination of measurement data necessary for estimation, the user can easily identify the state of the chromatography apparatus. In other words, even when combining a plurality of monitoring conditions, the user can easily grasp the details of the monitoring conditions, and user convenience improves.

For the monitoring device according to one or more embodiments, the control part may determine the first combined conditional expression based on the first combined monitoring condition combining all inputted monitoring conditions. Thus, the user can, for example input only a simple single monitoring condition without inputting a complex first combined monitoring condition. Therefore, input settings of the monitoring conditions are simplified, and user convenience improves.

For the monitoring device according to one or more embodiments, the display part may display two portions of the first combined conditional expressions in two columns respectively and arrange the first conditional expression and the second conditional expression in the same row, the first conditional expression and the second conditional expression being mutually associated by the combined operational expression. Thus, even with a small screen and a limited display region and the like, it is possible to provide a display wherein the user can easily grasp the conditional expression. In other words, user visibility improves.

For the monitoring device according to one or more embodiments, the input part may receive input of comments relating to the second combined monitoring conditions based on the second conditional expression configured by the first conditional expression, the combined operational expression, and the second conditional expression, and the display part may further display the comment arranged in the same row as the first conditional expression and the second conditional expression. Thus, the user can easily grasp the effect of the combined monitoring conditions of column degradation and the like. Furthermore, even if there is no abnormality in a column, the user can grasp the state of other positions and the possibility of an abnormality appearing in those positions. Grasping these enables the user to rapidly perform accurate maintenance work.

The monitoring device according to one or more embodiments may further be provided with a communication part and a notification part, wherein the communication part may receive information of a parameter relating to the measurements taken using the chromatography apparatus from the chromatography apparatus, the control part may determine at least one of whether a second combined monitoring condition based on the second combined conditional expression configured by the first conditional expression, the combined operational expression, and the second conditional expression based on the information of a parameter relating to the received measurements is established, and whether the first combined monitoring condition is established; the notification part may notify that a corresponding condition is established based on an establishment determination according to the control part. Thus, making a determination using combined monitoring conditions combining a plurality of single monitoring conditions enables monitoring of the state of a chromatography apparatus that could not be grasped by only a single monitoring condition. Furthermore, the notification from the notification part enables the user to more intuitively grasp whether each conditional expression is established.

The monitoring system according to one or more embodiments is a monitoring system provided with any of the above monitoring devices and a process gas chromatography apparatus, wherein the parameters relating to the measurements taken using the chromatography apparatus may include: operation parameters of each constituent part that configures the measurement system for measurements taken using the process gas chromatography apparatus, and analysis parameters for the measurement results obtained by the measurements taken using the process gas chromatography apparatus.

According to one or more embodiments of the present invention, a monitoring method, a monitoring device, and a monitoring system for monitoring a state of a chromatography apparatus can be provided in which the details of monitoring conditions can be easily grasped even when combining a plurality of monitoring conditions.
