Problems in the development and application of software for processing of environmental energy‐dispersive x‐ray fluorescence spectra of thin samples are reviewed. The main principles and requirements for the software are discussed. A new program, EXFIT‐8.10, was created to meet these requirements and is described in detail. It is capable of analyzing up to 50 elements simultaneously by combining results from up to 3 different excitation conditions. A set of supporting and post‐processing programs is also included. The main specifications of the software and possible ways for improvement are discussed.
