Other sample holders are available for use with the Cary Eclipse.
Instructions for their use are included in the Help provided with the
Cary Eclipse software.
Purging
The nitrogen purging system is
not
supplied by Agilent, but the
following items are available from appropriate commercial suppliers.
Nitrogen
Liquid nitrogen (in conjunction with a heat exchanger) is
recommended because it is less expensive than compressed nitrogen
and is usually of better quality. If compressed nitrogen must be used,
the gas must be dry, oil-free and uncontaminated.
CAUTION
Never use compressed nitrogen from a supplier who uses oil or water in the
compression process. Such processes invariably leave fine particles of oil
suspended in the nitrogen, which will form an oily deposit on optical surfaces.
Use nitrogen from a supplier who fills containers from immersion pumps
lubricated with liquid nitrogen.
NOTE
The instrument warranty will be void if damage is caused by the use of
unsatisfactory nitrogen.
Pressure regulator and gauge
Operating pressure is from 70 kPa (10 psi). Always use an
appropriate regulator and gauge to ensure that the nitrogen supply is
consistently maintained at the correct pressure.
Supply tubing
Use clean, flexible plastic (polyvinyl chloride (PVC) or equivalent)
tubing of 6 mm (1/4 in) internal diameter.
