The clean room is dedicated to wet analysis of samples (sample dissolution and separation of chemical elements). It is a dust-free (pressurized under filtered air) and ventilated area (extraction of acid vapors). It consists mainly of materials/furniture that are inert to acids. The room is divided into several smaller areas dedicated to specific applications.

Equipment Hoods coupling laminar air flow and extraction, in solid polypropylene (Salare LFE series) Evaporation zones extracted and under flow of ULPA filtered air (Camfil Megalam) Recycled laminar flow hoods (Minaservice, Materlabo) Materlabo fume cupboards Savillex DST-1000 (1 L) and DST-4000 (4 L) distillers Hot plates inert to Analab acids Analab Evapoclean Closed Evaporation Systems

Materlabo hood used for acid distillation

Activity Dissolution of samples by acid etching (HF-HNO3) Dissolution under pressure (mineralization bombs, HPA – aqua regia) and alkaline fusion Dilution of samples for measurement of trace element concentrations by ICPMS Separation of the elements on ion exchange resin (Li, B, K, Cr, Fe, Rb, Sr, Mo, HSE, Ba, La, Ce, Nd, Sm, Eu, Lu, Hf, Pb, Th, U), by micro-distillation (Os) and liquid-liquid extraction (Re, Os, Po)
