Silver Gate™ Evolution ATR System

Tip: It is recommended that purge bellows are fitted during use to
help stabilize the spectrometer/instrument background even if
purging is not to be carried out.
Fitting the Purge Bellows P/N GS10707
1. With the Benchmark™ baseplate secured and the Silver Gate™
Accessory in position, measure the distance between the
spectrometer source and detector bulkhead/side walls and the flat
end faces of the Silver Gate™ Optical Unit. (This is dimension
“‘X”).
2. Using a sharp razor, cut lengths of the flexible purge bellows (
12 )
which are equivalent to the measured length (“X”) allowing an
additional 10mm for each.
Tip :
It is easier to cut the purge tube between the ridged grooves.
3. Unscrew the Silver Gate™ Optical Unit fixing thumb screw ( 1 ) and
remove the Silver Gate™ ATR Accessory from the sample
compartment.
Note:
Fit a polarizer at this stage if required. (GS12000 Series or
GS12510 Benchmark™ Compatible Accessory Polarizer Mount)
4. Fit the flexible purge bellows (
12 ) over both end apertures on the
optical unit and compress sufficiently to enable the whole assembly
to fit into the spectrometer.
5. Refit the Silver Gate™ ATR Accessory with the fitted purge bellows
to the Benchmark™ baseplate. Ensure the purge bellows ( 12 ) are
not obstructing the optical beam and then retighten the fixing
thumb screw (
1 ) to secure the Silver Gate™ ATR Accessory back
onto the Benchmark™ baseplate.
