Claim:
1. A method for determining a biological property of cells suspended in a liquid media, the method comprising: applying an electrical signal to said cells suspended in said liquid media at two or more signal frequencies to generate electrical property data; receiving biological property data obtained using an alternate analytical technique; generating at least one value representative of frequency dependence of said electrical property data; determining a first relationship between said biological property data and said electrical property data; determining a second relationship between (1) said value representative of the frequency dependence of said electrical property data and (2) a divergence between a magnitude of said biological property data and a magnitude of said electrical property data; determining a calibration function by combining said first relationship and said second relationship; by a computer, calculating said calibration function with subsequent electrical property data to determine said biological property of said cells; and adjusting one or more environmental conditions of said liquid media in response to determining said biological property of said cells.
