| Abstract: | An Ultra-Clean Chemical Laboratory (UCCL) has been built at IRMM to allow reliable, contamination-free chemical treatment
of samples prior to inorganic elemental or isotopic analysis. The concept is intended to guarantee a dust-free environment
as well as resistance to corrosion even if hot concentrated mixtures of acids are continuously used, thus establishing not
a clean or dust-free room but a clean laboratory. The excellent air quality is demonstrated both by particle measurements and the analysis of acids
purified by subboiling distillation in the UCCL.
