Abstract

The invention relates to a method for taking a sample from a system. A user (1) enters an analysis request to a computer system (4), whereupon a connection is established between the computer system and a databank. As a result of the analysis request an information catalogue is generated from the databank, from which the at least one sample holder (13) to be used is suggested or provisionally selected for the user (1) by means of a input and/or output device (5). The invention further relates to a method for production of a request data set for a sample for analysis. An information catalogue, corresponding to an entered analysis request is proposed to the user (1), the data of which from the information catalogue for the entered analysis request may be optionally added to or edited by the user (1). From said data, test conditions for the sample to be analysed are generated and processed with the holder data, a system identification number and a request number to give a uniform machine-processable request data set which is transmitted to the laboratory (2) engaged for the above.
