Gas requirements 
The Cary 3500 UV-Vis requires the supply of a compressed gas (nitrogen or air) 
when the Peltier temperature-controlled modules are used. It is required to prevent 
condensation of the sample compartment when temperatures below ambient are 
used. The supplied gas must be dry, oil and particle free and non-combustible.
