Abstract:
OBJECTIVETo establish characteristic parameters of complex impedance spectrum of rabbit whole blood cells.
METHODSThe AC impedances of 30 blood samples from the 10 rabbits were measured with the Agilent 4294A impedance analyzer at frequency range of 0.01-100 MHz and its characteristic data were analyzed by the Bode plot, the Nyquist plot and the Nichols plot.
RESULTSThe impedance amplitude and phase angle of rabbit blood cells was frequency-dependent. The impedance spectrum of rabbit blood cells had two characteristic frequencies: the 1st one (f(C1)) was 2.58 MHz, the 2nd one (f(C2)) was 5.21 MHz.
CONCLUSIONThe frequency properties of whole blood cells can be obtained by the analysis of impedance spectrum.
