Method of analyzing samples, analyzing device and computer program

An analyzing device that is configured to receive a microplate comprising a plurality of wells, each of the wells being configured to receive a sample, wherein the analyzing device comprises:

• an illuminator for illuminating a sample from above the microplate via an upper end of a well of the microplate using electromagnetic radiation having a first predetermined wavelength or wavelength range,
• a detector configured for determining an intensity of light emitted via the upper end of the well by a plurality of measurement areas of the sample and having a second predetermined wavelength or wavelength range,
• the device being configured to count the number of spots emitting light having the second predetermined wavelength or wavelength range, and
• the device being configured to determine, based on the determined intensities of light emitted by said plurality of measurement areas, a result value representing the total amount of light emitted by the sample and having the second predetermined wavelength or wavelength range.
