The method comprises the steps of detecting using a first detector emissions of a first type from the sample in response to the beam scanned over the area of the sample. Then, using spectral information of detected emissions of the first type, at least a part of the scanned area of the sample is divided into multiple segments. According to the disclosure, emissions of the first type at different positions along the scan in at least one of said multiple segments may be combined to produce a combined spectrum of the sample in said one of said multiple segments. In an embodiment, a second detector is used to detect emissions of a second type, and this is used to divide the area of the sample into multiple regions. The first detector may be an EDS, and the second detector may be based on EM. This way, EDS data and EM data can be effectively combined for producing colored images.
