Dual frequency mode (providing data every 6 sec):
This mode measures at a cell type specific frequency (fmes) usually 1 MHz for mammalian cells and bacteria, and 2 MHz for yeast and is continuously and automatically corrected for the background permittivity measured at high frequency (fhigh). The permittivity measured by Incyte is specific to viable cells and correlates with the viable cell density, specially during the exponential growth phase.
Frequency scan mode (providing data every 30 sec):
As a research tool it is possible to run a frequency scanning (providing data every 30 sec)
The polarization behavior of cells varies strongly at different frequencies. Cells fully polarize at low frequency whereas they hardly polarize at high frequency. The Incyte Scan measures the permittivity signal at 17 different frequencies between 0.3 and 10 MHz
and provides additional information especially on the cells physiology.
During the Incyte Scan the most relevant parameters - Δεmax, fc, and α - are automatically calculated and displayed.
