This chapter provides information and typical floor plans for rooms containing a
MERCURY-VX
NMR spectrometer system.
6.1 RF Cable Harness
The rf cable harness between the console and the magnet leg is about 6 feet long. Therefore,
when arranging the system, the magnet must be within about 6 feet of the console.
6.2 Magnetic Field Considerations
To prevent damage to the stored data, the host computer, SMS controller, and the data
storage media (e.g., hard disks, floppy disks, streaming tape cartridge) must not be located
in a field that exceeds 5 gauss. Refer to
Chapter 5, “Stray Magnetic Fields,” on page 35
stray magnetic field plots.
6.3 Typical Room Layouts
In the room layout illustrations, the dotted circles around the magnets represents the
possible radial extent of the 5-gauss stray field. In the room layouts with the optional SMS
autosampler, the location of the autosampler depends on the orientation of the magnet.
Note that long-hold magnets are the same size as the 400/54 cryostat, but use the
appropriate 200-MHz or 300-MHz solenoid. This means that the 200-MHz long-hold
magnet cryostat is the same size as the 400/54, but the field strength and stray fields are the
same as a 200-MHz magnet.
The following typical room layouts are provided:
•
