Pulsed Calibration Light Source for Cytometers Overview quantiFlash® is an ideal tool to obtain the best resolution and sensitivity of cytometers. Unlike calibration beads, quantiFlash delivers consistent and uniform light pulses. Their intensity and duration is freely adjustable. Perfect Light Pulses Perfect light pulses with almost no unwanted non-liniearities outperform bead-based calibration particles. A precise LED pulser light source is the ideal tool for monitoring and calibration in flow cytometry. Standard Protocols Use standard calibration protocols or develop your own. Performance Test of PMTs Performance tracking in long-term or inter-laboratory studies as well as comparability of instruments become available with the quantiFlash LED pulser. The proven perfect linearity of quantiFlash and the delivered light intensity within up to 6 decades allow the measurement and comparison of the dynamic range and the signal-to-noise ratio of PMTs. The optimal PMT voltage for the cytometer detector channels can be found based on the results obainted with quantiFlash. Performance Tracking & Result Comparison quantiFlash enables user to determine the resolution and sensitivity (reflected by Q and B) for each detector so that instrument comparison as well as long-term experiments become more efficient.
