The Gliwice Radiocarbon Laboratory was established in 1967 by Prof. Włodzimierz Mościcki, a pioneer in the ¹⁴C measurements with gas proportional counters. Since then, the unit instantly developed and at present is officially distinguished in the University structure as the Radiocarbon and Mass Spectrometry Laboratory, a part of the Division of Environmental Isotopes at the Institute of Physics – Centre for Science and Education. Another unit within the Division is a Luminescence Dating Laboratory, and both lab teams naturally cooperate to solve scientific questions in various disciplines: Earth and environmental sciences, physics, and archaeology. The present human potential of the Laboratory are 12 permanent employees, including 9 persons in the scientific positions and 3 technicians.

The equipment of Laboratory fills the space area of ca. 400 m². Fully furnished chemical preparation rooms are equipped with fume boards, water demineralisers, analytical and micro- balances, ultrasonic baths, lyophiliser, microscope etc. Most important equipment is:
1. AMS Laboratory (responsible: Natalia Piotrowska):
-Automated graphitisation equipment AGE-3 (IonPlus AG)
-VarioMicro EA for combustion of organic samples
-Manual tube cracker for CO₂ introduction
-Vacuum line for carbonate decomposition and CO₂ purification
-AMS MICADAS (IonPlus AG) spectrometer scheduled to be installed in 1st quarter of 2022

2. LSC Laboratory (responsible: Adam Michczyński):
-Two Quantulus 1220 spectrometers
-Two ICELS spectrometers
-Prototype multi-chamber scintillation spectrometer for rapid measurements of low radioactivities
-Vacuum lines for sample combustion and conversion to benzene
-Oxygen-flow line with two ovens: two-zone oven Czylok PRS-50, infra-red oven Behr IRF-10 for stepped-combustion

3. Mass Spectrometry Laboratory (responsible: Jacek Pawlyta):
-Continuous-flow IRMS IsoPrime for HCNO isotope composition determination
-Elemental analyser EuroVector EA3000 for analysis of solid samples with combustion or pyrolysis
-MultiFlow device for preparation of water and carbonate samples

In addition, the field sampling equipment is available: Wardenaar and Russian (instorf) coring devices for sediment sampling and drills for tree-ring coring. The LINTAB equipment for tree-ring width measurement was recently upgraded with a new microscope.

At present state the Radiocarbon and Mass Spectrometry Laboratory carries out yearly ca. 400 radiocarbon dates and a similar number of stable isotope determinations, for the research projects in cooperation with national and international teams and external orders.

Most important projects carried out in the Laboratory:
1) Centre for Isotope Methods CEMIZ (designed to AMS spectrometer installation); leader: Natalia Piotrowska
2) Laboratory for Research and Analysis of Working Conditions of Industrial Professions; leader: Adam Michczyński
3) Archives of Spatial and Temporal Evolution of environmental Contamination related to mining and smelting activities in Upper Silesia, Poland; leader: Jarosław Sikorski
4) Abrupt increase of radiocarbon concentration due to high Sun activities in VIII and X century AD based on measurements in annual tree rings; leader: Andrzej Z. Rakowski
5) Chronology of the Inca expansion in Cordillera de Vilcabamba (Peru); leader: Andrzej Z. Rakowski
6) Multi-proxy investigations and advanced methods of determining numerical time scales in the reconstruction of the evolution of inland dunes in Poland during the end of the last glaciation; leader: Piotr Moska
7) Smaller research and commercial projects: ca 30/year
