Method and system (100) for characterizing lipid content in microalgae are disclosed. An input signal is transmitted to a resonator cavity (102) containing a sample microalgal suspension and a frequency response curve is obtained. Subsequently, a set of sample parameters is determined based on a Gaussian distribution modelling of the frequency response curve. An amount of lipid content in the sample microalgal suspension is determined based on correlation between the sample parameters and a set of reference parameters, wherein the reference parameters correspond to specific amounts of lipid content.
