 | Reference materials storage |
 |
Storage of reference materials is essential for preserving the integrity of
the samples. As a part of each reference material production cycle, the study
of stability is conducted. Based on that study the appropriate storage
conditions for each material are defined.
The wide range of materials provided by IRMM, calls for a wide range of
storage conditions. For example, easily flammable materials need to be stored
apart from other materials, and some others need to be stored at room
temperature in the dark. An increasing number of sensitive materials also need
to be kept in cooled storage rooms.
IRMM has facilities to store materials at +18, +4, -20, -40 and -70°C. For
storing extremely delicate products IRMM operates tanks with liquid nitrogen
where samples are kept above the liquid nitrogen surface at a temperature of
approximately –160 °C.
