Sofnolime, 1 kg
Drierite
Drierite (anhydrous 97% calcium sulfate (CaSO
4
) and 3% cobalt chloride) is an excellent H
2
O absorber
making it an ideal choice for controlling H
2
O. Both self-indicting (blue to pink) and non-indicating Drierite
can be can be used with the TARGAS-1. It can be regenerated easily by simply spreading out the
granules one layer deep and placed in a preheated oven for 90 minutes at 230 °C or 425 °F. The
regenerated material should be returned to the original glass container and sealed while hot. The color of
the self-indicating Drierite may become less distinct on successive regenerations due to the migration of
the indicator into the interior of the granule and sublimation of the indicator.

Molecular Sieve
Molecular Sieve is used to scrub both CO
2
and H
2
O from the air in order to perform Auto-Zero and 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 if there is any doubts as to the status of this desiccant.
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 TARGAS-1 is not going to be used for an
extended period (i.e. days) to preserve the desiccants.
