NOTICE
The warranty does not cover damage to internal optics or electronics caused by
failure to use sample compartment windows or to adequately purge the sample
compartment.
Lamp Compartment Access Panel
A mercury lamp accessory is available for the Evolution Pro either as a factory-installed
option or as a user (or Field Service Engineer) installed accessory. To access the lamp
compartment, turn the locking screw 90 degrees counterclockwise and lift the panel upwards.
Corrosion Protection
The spectrophotometer contains precise optical components that may be damaged by a
corrosive environment.
•
Quartz windows on the monochromator cover protect the monochromator from
corrosive gases in the sample compartment to some extent. However, the monochromator
is not sealed and corrosive gases from the sample compartment can still make their way
into the monochromator through other routes.
•
There are no windows between the detector compartment and the sample compartment.
If your samples will produce corrosive vapors you should purge the sample compartment with
a continuous flow of draw gas such as dried air or nitrogen.
Purging the Sample Compartment
Purging the sample compartment removes moisture from the sampling area for subambient
temperature-controlled measurements. It also serves to flush potentially harmful vapors from
volatile samples out of the sample compartment.
