Pollen Analysis by Impedance Flow Cytometry

Amphasys’ cell analyzers are based on Impedance Flow Cytometry. This means that an electrical field is applied in the microfluidic chip and the changes of the electrical resistance (impedance) of the fluidic medium are measured when cells pass through the applied electric field. The absence of optical components reduces set-up times and maintenance to a minimum – and even allows to carry out measurements in the field or in the greenhouse.

Patented Biochip Technology

The heart of the cytometer consists of a patented microfluidic chip equipped with microelectrodes. This high-sensitivity sensor measures changes of the electrical resistance (impedance) of the fluidic medium when cells or other particles pass through the applied electric field.

To ensure the highest possible sensitivity, Amphasys provides chips of different diameters for the whole range of small to large pollen cells (up to 200 µm).

Amphasys guarantees for 1000 measurements of one chip (misuse excluded).


A technology that provides detailed insights into small structures like cells need a software that enables in-depth analysis.

The portable Ampha P20 is equipped with AmphaSoft Xpress for fast, routine measurements operated on a touchscreen.

The lab instrument Ampha Z40 is equipped with the newest version of AmphaSoft PRO which allows to uncover all research details and display the results in a clear and comprehensive way. Measurements (workspaces) taken with the AmphaSoft Xpress can be further analyzed with AmphaSoft PRO.
