(2) the analysis action in analytical equipment
Next, being illustrated using Fig. 3 flow chart to the analysis action in the analytical equipment 100 of the 1st embodiment.
After zero correction and/or span calibration is performed to analytical equipment 100 as needed, first, mould will be analyzed
Formula is set as the 1st analytical model.Then, β rays are irradiated from beta ray source 51 to the 1st position P1, from x-ray source 71 to the 2nd position
P2 X-ray irradiations.And then, start to trap particulate material FP in the capture zone for being present in the 1st position P1.
Then, operational part 95 obtains β ray detections signal and the pulse signal conduct exported according to the intensity of fluorescent X-ray
Analyze data, calculates particulate material FP amount of collected and the species and amount of the element contained by particulate material FP
(step S 1).
In the trapping and analysis for performing particulate material FP, control unit 9 judge for example according to clocking capability or by
The current time of the calculating such as the clock count of clock signal whether on the basis of the moment (step S2).Reference instant can be for example based on
Every benchmark arbitrary decision as defined in various countries of 1 hour, every 1 day etc..
In the case of the moment on the basis of current time, as shown in Figure 4 A, at the time of reference instant T1, trap portion 3 stops
Only particulate material FP trapping, operational part 95 stops the acquisition (step S3) of analyze data.
Then, whether the analytical model in current selection is judged as the 2nd analytical model (step S4), is the 1st point in selection
In the case of analysis pattern, maintain the 1st analytical model constant, after capture zone is moved, restart particulate material
FP trapping and analysis (step S12~S14).Thus, catching for particulate material FP is performed repeatedly in reference instant every time
Collection, can calculate particulate material FP mass concentration.Furthermore, it is possible to regard the amount of collected in time per unit as quality
Concentration.
On the other hand, in the case where selection is the 2nd analytical model, start to catch according to after the arrival of last reference instant
During collection is played untill last reference instant is reached, if continue to trap particulate material FP, pre- orientation the 2nd is judged
Whether the amount of collected for putting the particulate material FP of P2 movements is smaller than ormal weight (step S5).
In the case where above-mentioned amount of collected is more than ormal weight, analytical model maintains the 2nd analytical model.On the other hand,
In the case where above-mentioned amount of collected is smaller than ormal weight, analytical model is switched into the 1st analytical model (step S6), maintain or
After analysis of shift pattern, analysis procedure enters step S12~S14.
On the other hand, in the case where current time is not reference instant, determine whether to detect particulate material
FP amount of collected reaches ormal weight and output notice signal (step S7).In addition it is also possible to by big after 31 pairs of trappings of suction pump
Whether gas A2 attraction flow is reached below regulation flow, to detect whether particulate material FP amount of collected reaches regulation
Amount.
In the case of non-output notice signal, continue particulate material FP trapping and analysis (step S2).Separately
On the one hand, in the case of output notice signal, trap portion 3 stops particulate material FP trapping (step S8).
After trapping is stopped due to output notice signal, determine whether to continue to obtain analyze data to micro- from detector 73
Fine granularity material FP is analyzed (step S9).It is standby to terminate to the analysis in the case where analyzing and continuing.
For example, as shown in Figure 4 B, T3 continues in the case of obtaining analyze data at the time of output notice signal, at the moment
T3 does not move catcher/filter 1, and mobile catcher/filter 1 after T4, performs new trapping and analysis at the time of end is analyzed.
After notification signal is output and continue analysis terminate after, analytical model switches to the 2nd by the 1st analytical model
Analytical model (step S10).
By the switching from the 1st analytical model to the 2nd analytical model, when shortening particulate material FP analysis
Between, the capture zone that can will be present in the 1st position P1 with short range is replaced by non-capture zone.Even if as a result, notifying
The output frequency of signal is uprised, and also can more ensure the time for trapping particulate material FP, and it is balanced and
Efficiently take into account trapping and analysis.In addition, by the analysis of shift pattern after the 1st analytical model terminates, can reliably perform
Analysis before and after analysis of shift pattern.
After analysis of shift pattern, judge that can period terminate micro- untill next reference instant after output notice signal
Fine granularity material FP analysis (step S11).
As shown in Figure 4 C, T3 plays next reference instant T1 time Δ t at the time of being judged as from output notice signal1
Execution time that is, the 2nd time Δ t than the 2nd analytical model2It is small and can not terminate small before next reference instant T1
In the case of the analysis of particulate matter FP next round, catcher/filter 1 is moved in next reference instant T1.
On the other hand, operational part 95 is after next reference instant T1 is passed through, analysis object capture zone from the 3rd position
P3 is moved to (moment T2) after the 2nd position P2 and starts to obtain analyze data.Thereby, it is possible to reliably perform particulate material
The analysis of FP next round.
On the other hand, as shown in Figure 4 D, in time Δ t1For the 2nd time Δ t2More than, and make to trap even in moment T3
Filter 1 starts the analysis of next round after moving, T7 terminates the analysis at the time of still being able to before next reference instant T1
In the case of, move catcher/filter 1 at the time of T3 at the time of after notification signal is just exported.In addition, operational part 95 is in trapping
Start the analysis of next round at the time of the mobile end of filter 1 at the time of T6.
Thereby, it is possible at the time of after notification signal is exported merely through the short time, start catching for particulate material FP
Collection and analysis.
When being reached at current time at the time of move catcher/filter 1, make the capture zone of catcher/filter 1 along length
Move (step S12) in direction.Thus, the capture zone for being present in the 1st position P1 is moved to the 3rd position P3, on the other hand, is not caught
Collection region (new capture zone) is moved to the 1st position P1.Then, the output (step S13) of expiry notification signal.
Next, trap portion 3 starts to trap particulate material in the new non-capture zone for reaching the 1st position P1
FP.On the other hand, operational part 95 starts the acquisition of the analyze data of the particulate material FP to being newly moved to the 2nd position P2
(step S14).
For example, after stop button is pressed or detects the exception of device, analytical equipment 100 stops above-mentioned analysis work
Sequence, and in the case of in addition, above-mentioned step S2~S14 (step S15) is performed repeatedly.
Using above-mentioned analysis procedure, analytical equipment 100 as shown in the display example of Fig. 5 analysis result, even if small
Particulate matter FP amount of collected changes, and also can efficiently take into account execution trapping and analysis.In addition, no matter particulate material
How is FP amount of collected size, can obtain intentional analyze data.
2. the 2nd embodiment
