2.4.2 Ordering information for the high- and low-pressure
nitrogen systems
You must provide the high- and low-pressure nitrogen systems that connect
to the back of the MegaBACE instrument. You must also provide the
high- and low-pressure cylinders, which you can obtain from your local
supplier. Make sure you order 5.0 ultrahigh purity nitrogen.
The specifications for the nitrogen are—
• 99.999%
• O
2
< 1 ppm
• H
2
O < 3 ppm
• THC < 0.5 ppm (Ar and Ne Free Basis)
The following sections provide information for ordering the nitrogen systems.
Ordering nitrogen systems within the US
• Option 1: Ordering high- and low-pressure manifold assemblies— You
can order a high- and a low-pressure nitrogen manifold assembly, each of
which includes the high- and low-pressure regulators and tubing. Table 2-4
provides the ordering information for the manifold assemblies.
• Option 2: Ordering separate parts— If you are using multiple instruments,
contact MegaBACE System Technical Support for assistance. See
Assistance in the preface for contact information.
Note: The female adapter comes in the instrument accessory kit.
