Installation Site Requirements
This section describes requirements for the system installation site. Each requirement must be met before an installation can be scheduled. Contact your installation coordinator if you have any questions about the requirements.
General Site Considerations
Requirement: Instrument will be far enough away from external sources of vibrations and magnetic fields.
When choosing an installation site for the system, consider how the external environment, particularly external sources of vibrations and electromagnetic fields, might affect the system.
Min. Distance from System (ft)
Min. Distance from System (m)
Possible Effect on System
Vibrations, magnetic field
Stairwell, loading dock, compressor, heavy equipment/machinery
High voltage lines & transformers
High-field electromagnets, forklift trucks
Laboratory Entrance Clearance
- Requirement: Entrance and access to the installation location is adequate for system crates and pallet jacks.
Laboratory Space and Load Requirements
- Requirement: Sufficient laboratory space including service access
- Requirement: Floor can support system weight
- The magnet holds about 64 L of liquid helium. A magnet quench will not typically boil off the entire 64 L.
- During a quench, helium gas fills the room from the ceiling down, so set up fans accordingly.
- The expansion ratio of liquid helium at room temperature is about 740:1, which means that one liter of liquid helium expands to about 740 liters of helium gas. To calculate CFM, use 26.13, which includes the expansion ratio.
- Requirement: Floor vibrations are within the specified limits
High levels of vibration can have an adverse affect on the quality of NMR data. The Quantum-I-Plus 400 is equipped with state-of-the-art vibration isolation equipment. Ground floor or basement sites are generally preferred for systems because the natural resonant frequencies of most building structures are typically at low frequencies and horizontal in direction. Also, cement slabs on grade are generally stiffer with less low-frequency vibrations and preferred to suspended floors.
Frequency of Vibration
Greater than 15 Hz
no single peak greater than 400 µg
10 to 15 Hz
no single peak greater than 200 µg
5 to 10 Hz
no single peak greater than 75 µg
Less than 5 Hz
no single peak greater than 10 µg
- Requirement: Relative humidity can be maintained within the specified range.
Operating the system at a very low humidity may result in the accumulation and discharge of static electricity, shortening the life of electronic components. Operating the system at high humidity may produce condensation and result in short circuits. Suggested humidity range is 20% to 80% non-condensing.
- Requirement: Lab temperature can be maintained within the specified range.
The average steady-state heat load of the console is 500 watts. The host workstation heat load is approximately 400 watts.
The airflow around the system must be adequate. The air conditioning system must be capable of maintaining a constant temperature in the immediate vicinity of the system. The temperature around the magnet must be maintained within ±1.0 °C (±1.8 °F) during an experiment and during shimming. Do not place the system near air ducts, windows, or heating and cooling systems. Optimal operating temperature is 60-75 °F or 17-24 °C.
NOTE: As laboratory temperature increases, system reliability decreases due to heat generated by electronic components. This heat must dissipate to the surrounding air for reliable operation.
- Requirement: Lab is free from excessive particulate matter.
The laboratory must not have excessive dust, smoke, or other particulate matter. Particulate matter can block airflow vents causing the electronics to overheat.
Compressed Air Requierments
- Requirement: Compressed air or nitrogen is clean and dry, and the appropriate regulator and gas lines are installed.
Quantum-I-Plus 400 system operation requires a constant flow rate of air or nitrogen. Install the air supply with 1⁄4 in. (0.635 cm) connectors.
- If compressed air will be used, it must be clean, dry, and oil-free, with less than 0.1 ppm total hydrocarbons, including methane, and a −40 °C dew point.
- If compressed nitrogen will be used for the system supply, the gas must be dry, oil-free, and magnetically clean (for example, free of rust), with a dew point of –193 °C (80 K).
45 lpm (95 SCFH)
80 psig (585 kPa)
27 lpm (57 SCFH)
80 psig (585 kPa)
100 lpm (127 SCFH)
100 psig (585 kPa)
- Requirement: Specified electrical supply and power outlets are installed.
The Quantum-I-Plus 400 system requires a single-phase power source with earth grounds hard-wired to the main power panel ground.
Max. Current Demand
Number of Outlets
- Requirement: The necessary supplies and equipment will be available for the system installation.
This section describes the requirements to ensure a successful installation. The lab should have adequate helium and nitrogen gas for magnet installation.
2 cylinders about 80,000 liters or 285 cu. ft.
Low pressure regulator less than 30 psi
He gas flow regulator and flow meter 0-40 lpm (0-80 CFH)
Purity ≥ 99.995% or US Bureau of Mines Grade A.
1 cylinder or a fixed source
Dry, oil free and magnetically clean with a dew point of -193 °C
Cryogens for Magnet Installation
200 liters at short notice delivery within 48 hours. Dewar should be compatible with a siphon diameter of 0.5 in (12.7 mm)
Adapter for connecting 9 mm (3/8 in) ID rubber tubing to the LN2 container.
Magnet Support Requirements
- Requirement: The appropriate facilities engineer and tools will be available to assist the field service engineer during magnet installation.
Facilities personnel must be available during the magnet installation to assist with drilling holes for anchor bolts.
The magnet anti-vibration legs must be fastened to the floor. Q.One supplies four 1⁄2-inch diameter anchor bolts for each leg. A minimum depth of 2.5 in is required for each bolt. A drawing shows the bolt hole pattern.
The magnet can also be supported by ropes attached to the ceiling. If overhead ropes are used, the ceiling of the building should be evaluated for structural strength. The ropes should have a small amount of slack so that building vibrations are not transmitted to the magnet. These vibrations can cause artifacts to appear in the NMR spectra.
- Requirement: The shipping cartons were examined for damage, and if damaged, the conditions were reported and noted on the freight weigh bill.
- Water stains
- Cuts, punctures, or deep indentations
- Crushed corners or excessively abraded edges
- Blue beads in the Tip (N) Tell arrow point
- Two Tip (N) Tell indicators and labels are on the exterior of the shipping boxes. Read and follow the instructions on the label. If the Tip (N) Tell arrow point is blue, the box was on its side or tipped in transit and instrument damage may have occurred.
- If you see one or more of these conditions on any shipping carton:
- Report the conditions to the carrier when you receive the shipment
- Note the damage on all copies of the shipping documents
- Write a brief description of the damage
- Tell the driver to sign next to your comments to signify agreement with the observations
- Contact local Customer Service to report the damage
- If no external damage is apparent, sign the receiving documents “Received but not inspected” to indicate that the boxes have not been opened.
- Systems are shipped either FOB Shipping Point or FOB Destination. The manner of shipment determines who is responsible for filing a claim against the carrier if the system was damaged in transit. Most systems are shipped FOB Shipping Point, so any damages incurred in shipment are the responsibility of the purchaser and the carrier. Contact local Customer Service for assistance with filing claims and billing repairs. If the system is shipped FOB Destination, contact local Customer Service, which will file a claim against the carrier.
- Q.One will not accept liability for damage if obviously received damaged materials were received without noting the damage on the receiving documents.
- Move the shipping containers to a warm, dry, secure area near the place of installation.
- Do not open any boxes until the Q.One Representative arrives to do the installation.
Unpacking and Installing
Cryogenic Equipment Rack
Various items are used around the magnet for routine maintenance and cryogen handling, including a helium transfer tube, Tygon® tubing, and insertion tubes. Protect the cryogenic equipment from damage and keep it conveniently available. Provide a rack to hold the items. A 1.2 m x 2.4 m (4 ft x 8 ft) pegboard hung on a wall, with wood/plastic pegs, works very well.
