3.2 Creating an Analysis Method 3 - 6 3 EX WL Enter an excitation wavelength. 4 EM WL Enter an emission wavelength. 5 Time unit Set a time unit. 6 Scan time Set a wavelength scan speed. For the relationship between scan time and sampling interval, refer to Appendix H. 7 Delay After pressing the Measure button, measurement is started following the delay time set here. It is used for temperature stabilization, etc. In repeat measurement, it is the time until the start of the first measurement. The delay time is invalid for the second and subsequent measurements. 8 EX Slit Select a slit width on the excitation side. 9 EM Slit Select a slit width on the emission side. 10 PMT Voltage A function for controlling the voltage of the photomultiplier detector (photomultiplier tube). As a reference, changing from 400 V to 700 V increases the data value about two digits and changing from 700 V to 950 V increases it about 1 digit. When a check mark is put for PMT Voltage 0-1000V, setting is allowed within a range from 0 to 1,000 V. 11 PMT Voltage 0-1000V When a check mark is put in this box, the photomultiplier voltage is settable within a range from 0 to 1000 V. 12 Response Set a response time. 13 Shutter control The shutter can automatically be closed in other than measurement for slowing down sample deterioration due to the energy of excitation beam and opened when measurement starts.
3.2.2 3 - 7 14 Replicates Set the number of repeat measurements. 15 Cycle time Set a repetition interval. 16 Stopped Flow When a check mark is put in this box, the stopped flow mode is set. In this case, when you click the measurement start button, the system waits until an external start signal comes in. Then, measurement starts.
3.2 Creating an Analysis Method 3 - 8 When selecting the Monitor tab, the window in Fig. 3-5 appears. For the settable range of each parameter, refer to Appendix G. Fig. 3-5 Monitor Tab Assign the following parameters. 1 Y-Axis Max (maximum) Enter a maximum value for Y-axis on the monitor window. 2 Y-Axis Min (minimum) Enter a minimum value for Y-axis on the monitor window. 3 X-Axis Max (maximum) Enter a maximum value for X-axis on the monitor window. 4 X-Axis Min (minimum) Enter a minimum value for X-axis on the monitor window. NOTE: X-Axis Max and Min correspond to a display interval on the monitor window. For example, when Max and Min are 60 and 30, display on the window is made within 30 to 60 s, 60 to 90 s, 90 to 120 s and so on. 3.2.3 Monitor Tab 6 7 8 5 2 1 4 3
3.2.3 3 - 9 5 Open data processing window after data acquisition Select whether or not to conduct data processing after sample measurement. When selected (check mark is applied), an icon for this function (as shown in ) is displayed. NOTE: When the remaining memory capacity of PC in operation is very small (system resource is less than 20%), the data processing window will not open even if this item is turned ON. Either close the presently opened data processing window or restart the FL Solutions program. 6 Open data processing window after acquisition (Overlay) Select whether or not to conduct data processing with spectra overlaid after sample measurement. This setting is unavailable in repeat measurement. 7 Print report after data acquisition Select whether or not to print a report after sample measurement. When selected (check mark is applied), printing will be made automatically after measurement. The items set at the Report tab will be printed. 8 Overlay Spectra can be overlaid in the monitor window. This setting cannot be selected for repeat measurement.
3.2 Creating an Analysis Method 3 - 10 On selection of the Processing tab, the window in Fig. 3-6 will be displayed. For the settable range of each parameter, refer to Appendix G. Fig. 3-6 Processing Tab 1 Processing choices A list of data processing is displayed. Select a data processing item, and click the Right arrow button ( ). Then, the selected method appears in the Processing steps field. For example, select ‘Derivative’ and click , then ‘Derivative’ is displayed in the Processing steps field as shown in Fig. 3-7.

3.2.4 3 - 11 2 Processing steps The processing sequence is displayed. After measurement, data processing will be carried out in the order set here. How to Delete a Processing Method Select a processing method to be deleted and click the Left arrow button ( ). Then, the selected method disappears from the Processing steps field. Display and Change of Parameter When you click [+] in the Processing steps field, a parameter list is displayed. Click a parameter name to be changed, and it becomes changeable. For changing a ‘Derivative’ parameter, click [+] at the left of ‘Derivative’ in Fig. 3-7. The present derivative parameters (Derivative order, Smoothing order, Number of points) are displayed. For changing the derivative order, click ‘Derivative order,” and it is highlighted as shown in Fig. 3-8 to allow your change. Fig. 3-8 3 Peak Finding: Integration method Select an integration method for the peaks to be displayed in the data processing window. 4 Peak Finding: Threshold Set a detection limit for the photometric value axis of peak and valley. Peaks or valleys below the set value will not be detected.
3.2 Creating an Analysis Method 3 - 12 5 Peak Finding: Sensitivity Select the number of data points in the horizontal axis direction (abscissa). For detecting sharp peaks, select a sensitivity value of “1.” Or select “8” for detecting broad peaks. 6 Kinetics: Start time Enter a start time for kinetics (rate calculation). 7 Kinetics: End time Enter an end time for kinetics. 8 Kinetics: K-Factor Enter a K-factor for kinetics.
3.2.5 3 - 13 Select the Report tab, and the window in Fig. 3-9 will appear. Fig. 3-9 Report Tab This window is used to select a printout method and items of measurement results. 1 Output • Print Report A report will be printed.
