Abstract

The guideline describes the application of the deposition flux measuring device (IRMA) for the determination of the deposition flux of ammonia and ammonium compounds. Construction and operations of IRMA are explained as well as the way of processing the obtained samples and calculating the deposition flux. In addition, the guideline names possible analytical procedures for the determination of the samples´ ammonium concentration. By conjoining the sampling with a subsequent, defined analytical procedure for the obtained samples, the IRMA method presented becomes a complete measurement method. Finally, the guideline provides indications for quality assurance and specifies the performance characteristics as well as the way of presenting the results.
