How to use this Manual
This manual is intended for end users and has been written as a reference document
where you can skip to the relevant information.
Users can refer to the contents page to find the relevant information.
Please review each of the following sections carefully.
Thank you for selecting Peak Scientific to meet your gas generation needs, and should
you require any further assistance or support please do not hesitate to contact Peak
Scientific or the Peak Partner from which you purchased your generator.

Introduction
Precision is a modular system with differing flow rates that allows you to add multiple
generators as your gas and analysis demands change. The Precision Series will keep
your gas flowing with consummate accuracy and reliability, whatever your needs, while
fitting neatly into any lab space.
The Precision Nitrogen, Headspace and Nitrogen Trace Generators provide a constant
and consistent source of Nitrogen for detector make-up gas for GC applications, as
well as headspace vial pressurization, purge and trap, tube conditioning for thermal
desorption and sample blow down. In addition to these applications, the Precision
Nitrogen Trace model can be used for carrier gas in GC applications as it also removes
hydrocarbons by means of catalytic oxidation.
Other features include:
• Generates Nitrogen on demand from compressed air.
• Regenerative PSA Carbon Molecular Sieve to ensure Oxygen and Moisture removal.
• Minimum maintenance with only a filter change per annum.
• Small and Stackable.
With the Precision Nitrogen based on proven technology, it removes moisture and
oxygen to leave Ultra High Purity Nitrogen. The Nitrogen Trace further removes
Hydrocarbons (as Methane) to <0.05ppm.
To ensure these generator models meet our high expectations with regards to reliability
and performance, we have tested them extensively at our manufacturing plant and with
end users around the world to ensure reliability and longevity of the system.

Safety Notices
Peak Scientific Instruments cannot anticipate every possible circumstance which may
represent a potential hazard. The warnings detailed within this manual refer to the most
likely potential hazards, but by definition cannot be all inclusive. If the user employs
an operating procedure, item of equipment or a method of working which is not
specifically recommended by Peak Scientific, the user must ensure that the equipment
will not be damaged or become hazardous to persons or property.
Symbols
This manual uses the following symbols to highlight specific areas important to the safe
and proper use of the generator.
A WARNING notice denotes a hazard. It calls attention to an operating procedure,
process or similar, which if not correctly performed or adhered to, could cause
personal injury or in the worst case death. Do not proceed beyond a WARNING
notice until the indicated conditions are fully understood or met.
A CAUTION notice denotes a hazard. It calls attention to an operating procedure,
process or similar, which if not correctly performed or adhered to, could cause
damage to the generator or the application. Do not proceed beyond a CAUTION
notice until the indicated conditions are fully understood or met.
Caution, risk of electric shock. Ensure power to the generator has been removed
before proceeding.
Safety Notice to Users

Unpacking
Although Peak Scientific takes every precaution with safe transit and packaging, it is
advisable to fully inspect the unit for any sign of transit damage.
Check ‘SHOCKWATCH’ and ‘TIP-N-TELL’ labels for signs of rough handling prior to
unpacking.
Any damage should be reported immediately to the carrier and Peak Scientific or the
Peak Partner from where the unit was purchased.
Follow the unpacking instructions posted on the side of the crate. It will require two
people to remove the unit from the shipping crate and to manoeuvre the generator
onto the bench.
Please save the product packaging for storage or future shipment of the generator.
Note: Included with the generator is a “Fittings Kit” containing mains power leads for
UK, EU & US and also all the required fittings and warranty registration card. Be careful
not to discard these with the packaging.
Page 12

Page 13
Fittings Kit Contents
Supplied in the Fittings Kit are all the fittings required to connect the generator to the
application. The contents of the Fittings Kit are as follows:
1. Teflon Tubing x 3m
2. ¼” Compression Fitting x 1
3. 1⁄8” Compression Fitting x 1
4. UK Mains Power Cable x 1
5. EU Mains Power Cable x 1
6. US Mains Power Cable 110v x 1
7. US Mains Power Cable 230v x 1
All of the generators output ports are located on the output panel at the rear of the
unit.
Unpacking Instructions
The unit weight constitutes a two person lift and as such, safe lifting practices should
be employed; do not attempt to lift on your own, as you will significantly increase the
chance of injury & damage to yourself and others around you.
1. Remove the screws encircled in red around the bottom of the crate lid and lift
upwards.
2. Next, with someone on either side of the unit, position your hands underneath the
unit ready to lift.
3. Ensuring your knees are bent and your back is straight, lift the unit to the desired
location.

Page 14
Installation
Generator Environment
The generator is designed for indoor use only. It should be installed adjacent to
the application(s) it is supplying. If this is not convenient then the unit can be sited
elsewhere, however, consideration should be made of the lengths of pipe runs as
pressure drops can result from extended runs of pipe.
Performance of the generator (like all sophisticated equipment) is affected by ambient
conditions. Note should also be taken to the proximity of Air Conditioning outlets.
These can sometimes give rise to “pockets” of air with high relative humidity. Operation
of the unit within such a pocket could adversely affect its performance. Consideration
should also be given to the air flow around the unit. It is recommended that an air gap
of 75mm (3”) should be maintained down both sides and at the rear of the unit. Please
refer to the drawing below for the general dimensions of the unit.
Minimum Operating Ambient Temperature: 5 °C (41 °F)
Maximum Operating Ambient Temperature: 35 °C (95 °F)

Electrical Connection
Connect the generator to an appropriate 110 or 230 volt single-phase supply, refer to
the generator serial plate for input specification and ensure your supply matches the
requirements.
If the appropriate power cord is not supplied; a new plug, rated to at least 12 amps, can
be fitted by a qualified electrician.
This unit is classified as SAFETY CLASS 1. THIS UNIT MUST BE
EARTHED. Before connecting the unit to the mains supply, please
check the information on the serial plate. The mains supply must be of
the stated AC voltage and frequency.
EARTH/GROUND (E):- Green & Yellow or Green
LIVE (L):- Brown or Black
Neutral (N):- Blue or White
Electrical requirements are 110 or 230VAC nominal +/- 10% depending on chosen
model. However, running continuously at voltages outwith this is not recommended.
Extended periods at extremes can have a detrimental effect on the operation and life of
the generator.
If the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment maybe impaired.

Page 20
Air Purity
The Precision Nitogen Series generator should be connected to an air supply that, as a
minimum, meets ISO8753-1:2010 Class 1.4.1
Class 1 Particulate
In each cubic metre of compressed air, the particulate count should not exceed 20,000
particles in the 0.1 - 0.5 micron size range, 400 particles in the 0.5 - 1 micron range and
10 particles in the 1 - 5 micron size range.
Class 4 Water
A pressure dew point (PDP) of +3°C or better is required and no liquid water is allowed.
Class 1 Oil
In each cubic metre of compressed air, not more than 0.01mg of oil is allowed. This is a
total level for liquid oil, oil aerosol and oil vapour.
