The Laboratory for Sediment and Soil Analysis (SEDILAB) of the Geographical Institute, RCAES is the successor of the former laboratory of the same name of the Geographical Research Institute of Hungarian Academy of Sciences (MTA). Former laboratory mainly analysed loess and other sediments for Quaternary research in the 1970s and 1980s according to the researchers needs.

The laboratory as a self-contained unit was ceased to exist. The SEDILAB was re-established in 2004. The instrumentation was expanded at first with a laser particle sizer and with an NDIR-chemiluminescence TOC/TN analyzer. Further expansion of the instrumentation has been countinous since 2012.

As a consequence of the infrastructural development, the SEDILAB currently has five parts:
