HIGH PURITY* NITROGEN GENERATORS (NG SERIES)

Peak Scientific High Purity Nitrogen systems are designed to run 24 hours a day, 7 days a week and include a built-in air compressor. The NG Series Nitrogen Generators produce flow rates of between 250cc/min and 4L/min.

They utilize a “Pressure Swing Adsorption” (PSA) method to extract pure nitrogen from air. A highly efficient Carbon Molecular Sieve (CMS) is used to extract O₂, moisture, hydrocarbons & other trace gases to produce a continuous supply of high purity nitrogen.

The Peak Nitrogen Generators use a unique single column system where the column is alternately pressurized and vented under a finely tuned timing cycle. This guarantees high purity better than similarly sized 2-column systems.

Installation of the generator is simple and given the straightforward operation of the instrument, maintenance minimal.

PEAK combined laboratory air and nitrogen generators (ANG systems) are also available with flow rates of between 250cc/min and 3L/min.

NOTE:  All NG Series Nitrogen Generators are also available without the built-in air compressor for $500.00 less than the above prices.  If you are considering a Generator without the compressor, your external air source must be oil-free to avoid contamination of the Generator’s internal components.

*Quoted Nitrogen purity is based on Oxygen content and does not account for Argon present in the ambient environment.

HIGH OUTPUT NITROGEN GENERATORS (NM SERIES) FOR LC/MS SYSTEMS

Peak Scientific High Output Nitrogen systems are designed to run 24 hours a day, 7 days a week and come with or without a built-in air compressor. The NM Series Nitrogen Generators with compressor produce flow rates of between 18L/min and 32L/min. Larger systems, up to 420L/min., are available

The NM Series High Output Nitrogen Generators use hollow fiber membrane technology to efficiently separate nitrogen from other gases in air to produce a continuous high flow supply of high purity nitrogen for use in LC/MS systems using either APCi or ESi modes. The Peak High Output Nitrogen Generators are easy to use and install in minutes.

• Quiet: Locate directly in the lab
• Safe and cost effective: Replace cylinders.
• Mobile: Move to suit your requirements
• Experience: Over 10,000 systems installed worldwide.
• Design: Specifically for LC/MS/MS

PURITY STATEMENT: The question of purity often comes up with the ‘NM’ Series high volume nitrogen generators. Peak Scientific Instruments generators are tested under strict ‘factory controlled conditions’ against which the specifications are published. Nitrogen purity is tested and recorded at the factory as part of the QC test but excluded from the specifications for the following reasons.

Many environmental factors can affect purity such as ambient temperature, barometric pressure, and altitude. In addition, nitrogen purity will also vary directly with the Output Pressure and Mass Flow requirements of the mass spectrometer. It is therefore very difficult to predict and guarantee the exact purity of delivered nitrogen everywhere around the world.

Some generator manufacturers do quote specifications for purity and have chosen to provide a table with conditions and caveats which make it equally difficult to work out what the real figure truly is.

The Peak ‘NM’ Series high volume nitrogen generators are specifically designed to satisfy the requirements of LC/MS/MS systems only and are approved and/or specified by many LC/MS/MS OEM manufacturers. In all the years of testing and collaboration with the MS instrument manufacturers, as well as thousands of satisfied users in over 70 countries, nitrogen purity has never been an issue that has affected MS performance or experimental results.

This is what is really important and testament to the fact that the nitrogen supplied by the ‘NM’ Nitrogen Generators will meet your LC/MS/MS needs

While these Generators may be used for other lab or industrial applications, the output purity cannot be guaranteed.

HYDROGEN GENERATORS
(PH SERIES)

The PH Series Hydrogen Generators are the ideal alternative dangerous and expensive gas cylinders in your laboratory. Use the Peak Hydrogen Generator for your GC’s FID flame source, carrier gas, or your HALL detector’s reaction gas. All purities are at 99.9995%. Adjustable delivery pressure 0 – 100psi. Outlet port is 1/8″. Pressure dew point is -70°C/-100°F.

The Peak Hydrogen Generators use a proprietary ion exchange membrane technology to produce hydrogen on demand. The reliability of the membrane is assured due to its industrial and military pedigree.

To produce the highest purity hydrogen that analytical labs require, the Peak Hydrogen Generators employ a platinum catalyst in the electrode area which recombines any stray oxygen before it can contaminate the hydrogen stream.

The generators require only distilled or de-mineralized water and electricity to operate, making these systems safe and easy to maintain. The Hydrogen Generators feature sophisticated control and dual redundancy safety systems, with LED status indicators and audible alarms with automatic shutdown. Complies with all current OSHA and European regulations.

Benefits:

• 
• >99.9995% consistent purity
• Dual redundancy safety system
• H2 produced only on demand
• Microprocessor controlled
• Internal and external leak detection
• Visible and audible alarms
• No handling of caustic solutions
• Patented technology
• Hydrogen generation method: Peak Hydrogen Generators use ION Exchange Membrane, not Palladium, for hydrogen generation. Deionized water is required which eliminates the need for caustic solutions.
• Generator produces hydrogen only to meet your needs: Hydrogen is produced only on demand, and the unit can be switched off and on as often as required. This is not possible with a Palladium-style generator.
• Output pressure: Peak Hydrogen Generators produce up to 100psi from ION exchange.
• Other advantages: Fitted with water pump, Flow Indicator, convenient size, and constant output purity.
• NEW:  New for 2013 is Peak’s Precision 500 Hydrogen Generator which offers 500cc / min. hydrogen at 99.9999% for high purity carrier gas applications.  Couple several units together for higher flow requirements.

ZERO-AIR GENERATORS
(ZA SERIES)

The ZA Series Zero Air Generators produce high purity zero air (CH4 < 0.1ppm) and produces gas equivalent to UHP zero air cylinders at a fraction of the cost. The Zero Air Generators are available with or without internal air compressor and as a 19″ rack version. Air from the incoming compressed air supply is heated to 400°C and passes through a platinum catalyst chamber. Free carbon and hydrogen atoms combine with oxygen in the air to form carbon dioxide and water. The air then passes through a cooling coil to reduce its temperature to a safe level and to the outlet for use.

Benefits:

• Air < 0.1ppm THC
• Consistent results
• Easy to install
• Compact design
• Built in air compressor available
• Increases productivity
• Low maintenance
• Cost effective
