Experimental Study on Complex Impedance Spectra of Rabbit Whole Blood Cell / 医学研究杂志

ABSTRACT

Objective To establish characteristic parameters of plural impedance spectra of rabbit whole blood cell.Method The AC impedances of 30 blood samples from the 10 rabbits have been measured with the Agilent 4294A impedance analyzer at frequency range of 0.01～100MHz,then its characteristic data have been analyzed by the Bode plot,the Nyquist plot and the Nichols plot.Results(1)The impedance amplitude and phase angle of rabbit blood cell have a dependence of frequency.(2)The impedance spetroctra of rabbit blood cell have two characteristic frequencythe characteristic 1st frequency(fC1) was 2.58MHz,the characteristic 2nd frequency(fC2) was 5.21MHz.Conclusion The frequency properties of blood cells can be obtained by the analysis of impedance spectroscopy.
