Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Fig. 1 is a diagram showing the configuration of a liquid chromatography apparatus 100 (analysis apparatus) according to an embodiment of the present invention.
The liquid chromatography apparatus 100 includes a data processing device (control unit) 7 for controlling the whole, a mobile phase (mixed solution of eluent and solvent) 1, a pump 2 for transporting the mobile phase 1, an autosampler 3 for injecting a sample, a column 4 for separating components, a column oven 5 for keeping the column 4 at a constant temperature, a detector 6 for detecting the separated components, a display unit 10, and a reading unit 12.
The data processing device 7 is constituted by a computer having a control unit (CPU)9 for performing analysis and analyzing the analysis result, and a storage unit (hard disk or the like) 8 for storing the analysis result or the analysis result. The reading unit 12 is, for example, a barcode reader, and reads the lifetime information attached to the standard sample 200 as described later. The display unit (monitor) 10 displays the analysis result and the analysis result.
The detector 6 has a device for detecting the signal intensity, and detects the signal intensity with respect to time. As the detector, a three-dimensional detector having a plurality of detection elements and capable of simultaneously acquiring at a plurality of wavelengths may be used.
The sample is injected from an injector (not shown) of the autosampler 3, passes through the column 4 together with the mobile phase 1 fed from the pump 2, and is separated into various components in the sample.
The sample separated into components is detected by the detector 6. The signal of the detector 6 is sent to a data processing device 7 for data processing.
The column 4 is a device generally used as a separation section for separating components of a sample present in the mobile phase 1. The column 4 may be a packed column or a monolithic column. As the column packing material of the column 4, various types of packing materials such as an adsorption type, a distribution type, and an ion exchange type can be used. The column 4 is preferably placed in the column oven 5 so that the column 4 is kept at a constant temperature, and the separation of the sample can be performed with good reproducibility.
The storage unit 8 stores measurement conditions, calibration curve data, and the like for each type of sample in order to quantitatively analyze or qualitatively analyze the sample.
Fig. 2 is a schematic diagram showing a standard sample 200 (bottle 202). A standard sample 200 of liquid is placed in a bottle 202, and a bar code 210 is affixed to the outer surface of the bottle 202. The barcode 210 records the date of unsealing and the lifetime information of the standard sample 200.
Next, the processing performed by the control unit 9 will be described with reference to fig. 3.
First, the controller 9 controls the reading unit 12 to read the barcode 210 on the bottle 202 containing the standard sample 200 (step S2).
Next, the control unit 9 refers to the lifetime information recorded in the barcode 210, and determines whether or not the lifetime has expired (step S4).
If "No" in step S4, it is within the term, and therefore the first measurement using the standard sample, or the second measurement using the unknown sample of the standard sample (step S6),
then, the measurement result is displayed with the lifetime information added thereto (step S8), and the process is terminated.
Here, the first measurement refers to, for example, a measurement for checking normality of a standard sample to confirm whether or not a peak height quantified for the standard sample is within a predetermined range, or a measurement for creating a calibration curve using the standard sample.
The second measurement is, for example, quantitative analysis of the unknown sample based on the calibration curve created in the first measurement, or qualitative analysis for comparing the peak positions of the standard sample and the unknown sample.
Fig. 4 shows a printed matter obtained by adding lifetime information (consumption period) ST of a standard sample (cardamazepine) to the second measurement result (quantification of the concentration of cardamazepine of an unknown sample) as a display format in step S8.
In addition, fig. 4 shows the opening date SO in addition to the lifetime information ST of the standard sample.
In the present invention, the term "display of the measurement result" includes not only the control unit 9 controlling the printer and the like to display the measurement result as a printed matter but also the display unit 10 displaying the measurement result.
On the other hand, if yes in step S4, the controller 9 reports that the standard sample is replaced because the expiration date has passed (step S10). The method of notification is not limited, and for example, the notification may be performed by text or by voice when the user views the operation screen of the display unit 10.
As described above, since whether or not the expiration date information of the standard sample has expired is automatically determined and the expiration date information is automatically notified, the management of the standard sample is facilitated, and inaccurate measurement due to the use of the expired standard sample can be suppressed.
However, even if the standard sample is expired, it is sometimes desirable to perform measurement by urgently using the expired standard sample in a state where there is no standard sample in the lifetime at hand.
Therefore, in step S12, the control unit 9 determines whether or not the user wishes to use the expired standard sample. This determination can be made, for example, by: on the screen display of the display unit 10, a selection button for prompting the user whether or not to use the expired standard sample is presented to prompt the user to select the standard sample.
If yes at step S12, the control section 9 checks whether or not the standard sample is normal (step S14). This check can be performed, for example, by confirming whether or not the peak height of the standard sample quantified by the first measurement is within a predetermined range.
On the other hand, if no in step S12, the process ends.
If YES in step S14, the standard sample is judged to be normal, and the first measurement or the second measurement is carried out (step S16)
Then, the measurement result is displayed with the expiration date information and the information indicating that the standard sample is normal (step S18), and the process is terminated.
On the other hand, if no in step S14, return is made to step S10, facilitating the user to abandon the use.
Fig. 5 shows a printed matter in the form of a display in step S18, in which SU indicating that the standard sample (cardamazepine) is normal is added to the result of the second measurement (quantification of the concentration of cardamazepine in the unknown sample) in addition to the lifetime information ST of the standard sample (cardamazepine).
Thus, it is possible to easily grasp that the standard sample exceeding the expiration date is normal and can be temporarily used. In addition, it is preferable to perform the re-measurement immediately after obtaining the standard sample within the lifetime.
In addition, when yes is obtained in step S14, the control unit 9 may display the measurement result of the standard sample as shown in fig. 6.
The present invention is not limited to the above-described embodiments, and naturally, various modifications and equivalents included in the spirit and scope of the present invention are also included.
For example, the lifetime information added to the standard sample is not limited to the barcode, and may be an IC tag, for example.
