Instead, the problem of archaeological samples is that these samples are often too large to fit into a LA chamber of typical dimensions (a few centimeters in diameter only). Of course, taking a small part of the samples (e.g., with a microdrill, lancet, etc.) is a common solution in these cases, although special care has to be taken to minimize the risk of contamination. However, there are a number of alternative possibilities. For instance, Devos et al. used a cell with a flat exchangeable Plexiglas (Evonik Industries AG, Essen, Germany) bottom with a central aperture of 5,10, or 20 mm [48].
