Abstract
A method () for fixing at least one tissue sample () is carried out using a tissue processor (). The tissue sample () is introduced at a first temperature level and a first pressure level into a fixing reagent () containing at least one nitrogen-containing compound capable of pressure- and/or temperature-dependent release of at least one aldehyde. The tissue sample () is left in the fixing reagent () for a fixing time period during which the fixing reagent () is brought to a second temperature level above the first temperature level and/or to a second pressure level above the first pressure level. A concentration in the fixing reagent () of the nitrogen-containing compound is ascertained using at least one concentration measuring device () of the tissue processor (), and a signal is outputted on the basis of a measured value of the at least one concentration measuring device ().
