摘要: The invention relates to the identification and visualization of the spatial distribution of particular tissue states in histological tissue sections from mass spectrometric signals acquired with spatial resolution. The invention proposes a method by means of which regions of the tissue with similar mass spectra are found automatically, and it is further proposed that mass spectra of these regions are summed in order to improve the spectral quality to such an extent that known markers for tissue degenerations can be identified with increased certainty. Regions of similar mass spectra can be interconnected on a large scale, but can also be isolated from each other on a small scale.

摘要: The invention proposes preparing biological samples for spectrometry which contain cell structures and/or whole cells of human or animal origin (e.g. thin human and animal tissue sections) or prokaryotes (e.g. microorganisms), and which require constant relative humidity, in a temperature-controlled gas volume whose humidity is determined by a saturated substance solution, for example a suitable salt solution. The invention exploits a physico-chemical phenomenon called “deliquescence”, which manifests itself by keeping the relative humidity above the saturated substance solution constant with a high degree of precision when a specified temperature is maintained. Pure succinic acid exhibits deliquescence at approx. 99% relative humidity, for example. Since an enormous variety of deliquescent salts and other suitable substances are available, it is possible to find the suitable substance for almost any desired relative humidity, with adjustment of the temperature, where necessary.

摘要: The invention relates to a method for monitoring a quality of preparation workflows of analytical tissue sections for mass spectrometric imaging using a control sample to be processed and measured alongside the analytical tissue sections on the same sample support and ascertaining if characteristics of the control sample measurement fit into a range of characteristics of separate reference measurements from the same type of control sample.

摘要: The invention relates to a method for evaluating a quality of preparations of analytical tissue sections for mass spectrometric imaging using a reference sample to be processed and measured alongside the analytical tissue sections, and a kit-of-parts for a mass spectrometric imaging experiment including such reference sample.
