A lot of X-ray diffraction and X-ray fluorescence tests are performed in the department of Geoscience and Engineering to calculate a rocks likely ineralogical bulk composition. The old program used for this task was considered not user friendly enough, therefore an updating process of the old Mincomp program has been performed. During this updating process attention has been paid to justify the presence of the minerals in the Mineral Inventory of the program, and to the programming sequence by comparing Mincomp to other available programs, in order to write a new program. The results were compared to other available programs when writing of the program was finished, to identify differences between the programs and identify the shortcomings of Mincomp, as well as a justification of the used method. In general, the results of Mincomp are comparable with the results of other available programs, however the results on some samples differed in the calculated amount of Kaolinite and Illite, this is mainly caused by the allocation order of the program. It is recommended to investigate this difference a bit more and possibly revise the algorithm that is used at this moment.
