Running a Concentration Control Sample
Analyzing a concentration control sample at regular intervals allows you to verify count accuracy.
The software automatically uses the following settings when running a control sample:
• Electrolyte solution volume: 20 mL (Accuvette® ST only)
• Calibrator volume: 0.2 mL (200 µL)
• Dilution factors: none
•Mode: Volumetric (500 µL)
•Flush before run: Yes
• Number of runs: 1
• File save, print, or export: Off
•Size bins: 400 log diameter size bins from 8 µm to 12 µm
• Coincidence correction: On
•Edit: Off
•View: Differential number size graph, linear diameter X axis; graph displays number per mL
when run is complete
Setting Control Sample Options
To specify a control sample run and set recurring reminders:
1. Select
Calibration > Control Sample Options on the Main Menu bar.
NOTE
The Control Sample Options menu item is only visible to user types with sufficient security
privileges. The system administrator configures security settings. If the Multisizer 4 software is
running with no security, every operator can set control sample options, create an SOP, and
configure the software.
