Molecular Sieve
Molecular Sieve is used to finally filter any remaining CO
2
and H
2
O from the air supply during analyzer
ZERO to ensure system stability and accuracy for CO
2
and H
2
O. Unfortunately, Molecular Sieve is not
self-indicating and there is no obvious way to see that it is exhausted. It is therefore best to always
change the Molecular Sieve when changing the Drierite in the ZERO column.
Molecular Sieve can easily become contaminated through absorption of CO
2
and H
2
O from atmospheric
air. It is therefore strongly recommended and advised that Molecular Sieve is decanted into small air-
tight, glass containers sealed by electrical tape to minimize any exposure to air. The ZERO absorber
columns should be placed in a sealed polythene bag if the CIRAS-3 is not going to be used for an
extended period (i.e. days) to preserve the desiccants.
