The present invention relates to a microbiological test standard preparation for infrared spectroscopy, the microbiological test standard having at least two resealable vessels that are liquid-tight when closed, each of the at least two resealable vessels Dried biomass containing a predetermined amount of microorganisms. Dried biomass contains vacuum dried pellets. Said microorganisms in different vessels differ in at least one characteristic selected in particular from the group comprising species, subspecies, strains, serotypes, pathotypes, toxotypes and variants, and differ themselves by a predetermined microorganism The spectral distance between them appears. The present disclosure also includes a method of using a microbial test standard. The test standard and the method of use enable the determination and assessment of the reproducibility and spectral specificity of infrared spectroscopy measurements and subsequent evaluation steps. |
