Additional guidance on the SOLA II for Vapours
This user manual contains information relating to the use of the SOLA II and SOLA II Trace for both
liquid and vapour samples, this appendix provides additional guidance on the performance
specification, ranges and technical characteristics for vapour samples, in particular samples that have
a high dewpoint (Condensable Vapours).

SOLA 11 for Condensable Vapours
(CV)
The SOLA ll CV is a modified version of the standard SOLA ll for vapour samples, the function of
these modifications is to allow for the introduction of high dew point samples to the SOLA ll
without risk of condensation.
The SOLA ll CV version permits the entry of a heated sample line from the secondary sample
conditioning panel to enter the SOLA ll directly through the underside of the oven enclosure via a
heat shrink boot (sample line and heat shrink boot are not in the scope of Thermo Fisher Scientific)
but by the owner
or system integrator (or other).
Included in the oven are the sample injection valve, the forward and back pressure regulators (where
applicable), the sample/calibration valve and the divert valve.
