Peace of mind with i-Flow purity
i-Flow is a scalable on-demand nitrogen generation system capable of
producing nitrogen gas at levels of purity and flow rates to suit a wide
range of Gas Generation applications. Building on nearly two decades of
experience as a global leader in gas generation for scientific applications,
i-Flow is a culmination of Peak’s innovation and technological expertise.
All i-Flow generators come with an oxygen analyzer as standard to provide
real-time monitoring and display of nitrogen purity produced by the system.
In order to assure our customers of this purity, we had our i-Flow generators
independently tested by the National Physical Laboratory (NPL) in the
United Kingdom.
Controlled Verification
The NPL collected gas samples from the Peak Gas Generation manufacturing
facility under controlled conditions.
The gas was tested at four separate intervals: before entering the system,
after being processed by a Peak PureAir dryer, after being processed by
the i-Flow generator for 99% pure nitrogen and after being processed for
99.995% (50 ppm oxygen) pure nitrogen.
The gas samples were stringently tested using Gas Chromatography
(GC) with a variety of different detectors including thermal conductivity
detector, cavity ring-down spectroscopy, a pulse discharge helium ionization
detector, a non-dispersive infrared and a methaniser and flame ionization
detector. Further samples of gas were tested using the quartz crystal
microbalance method.
The NPL uses this robust and detailed methodology to detect impurities
down to trace detection levels, giving users assurance of the quality of
nitrogen produced.

NPL standards explained
The National Physical Laboratory (NPL) is the UK’s national measurement institute and is a world-leading center
of excellence developing and applying the most accurate measurement standards for science and technology
markets. They perform gas analysis measurements against primary reference gas mixtures that are directly
traceable to the SI unit.
Founded in 1900, the NPL was initially set up for standardizing and verifying instruments, testing materials,
determination of physical constants and is one of the oldest standardizing laboratories in the world. Now they
are a leading international measurement body, with measurement capabilities that are recognized across the
European Union and worldwide.
The NPL provided the analysis and data used by Peak Gas Generation to independently verify that the quality of
gas produced by the i-Flow system meets standard specifications set by global organizations such as European
Gas Generation Gases Association (EIGA), European Pharmacopoeia, European Commission’s Food Grade and
JECFA (Joint Food & Agriculture Organization of the United Nations/World Health Organization Expert Committee
on Food Additives) as well as numerous other industry standards in various fields. Furthermore, with Peak Gas
Generation’s IQ/OQ certification the i-Flow would also meet the specifications of USA Food & Drugs Administration
(CFR Title 21).
EIGA
EIGA is an industry body representing the vast majority of European, as well as many non-European
companies, producing and distributing Gas Generation, medical and food gases.

Based on the results of the extensive analysis by the National Physical Laboratory. Peak Gas Generation is satisfied
that the nitrogen gas produced by the i-Flow gas generators meets and exceeds the standards laid down by
both European Pharmacopoeia and the Joint Food & Agriculture Organization of the United Nations/World Health
Organization (JECFA). EIGA fully co-operates with all National Gas Generation Gas Associations and regional Gas
Generation gas associations around the world such as AIGA (Singapore), ANZIGA (Australia/New Zealand),
CGA (USA), JIMGA (Japan), SACGA (South Africa), which are all associated members to EIGA.
European Pharmacopoeia
Peak’s i-Flow generators are compliant with The European Pharmacopoeia’s standards for gas applications. The
European Pharmacopoeia is a legally binding quality standard applicable to all medicines sold in the European
Union covering ingredients dosage, analysis methodology and production of medicines.
Peak Gas Generation’s i-Flow generator has surpassed the requirements set out by this standard meaning that
our generator is suitable for supplying nitrogen in pharmaceutical production and manufacturing.
EC Food Grade
Gases used in food processing, for example as a propellant or as a packaging gas are classified as food
additives and are given E numbers (e.g. E941 for Nitrogen).
The NPL’s test results show Peak’s i-Flow generator comfortably meets the minimum EC Food Grade standards
set for food gas applications and therefore, is suitable for food gas uses, such as modified atmosphere packaging,
sparging and bottling of beverages.
USA Food & Drugs Administration Regulations
The Food & Drug Administration (FDA) is a federal agency of the US Department of Health & Human Services.
It is the executive department responsible for protecting public health by assuring safety, efficacy and security
of biological products, cosmetics, food supply, human/veterinary drugs, medical devices as well as products that
emit radiation. For food or pharmaceutical companies, the minimum standards of Current Good Manufacturing
Practices (cGMP’s) are regulated via Title 21 of the Code of Federal Regulations (CFR title 21), under Part 110 for
food and Part 210 for drugs.
With Peak Gas Generation’s IQ/OQ certification, companies regulated by these standards can ensure they meet its
specifications and this service can be provided at any point, whether requested at commissioning, servicing or at
any other stage.
ISO 8573-1: 2010
ISO 8573-1:2010 governs the acceptable levels of contamination per cubic metre of compressed air. In particular, the
ISO document specifies purity classes of compressed air with respect to particles, water and oil, independent of the
location in the compressed air system at which the air is specified or measured.
It is recommended that in order to achieve the purity specified by Peak’s i-Flow generator that a Peak PureAir
pre-filtration system is installed to ensure the quality of gas delivered to the i-Flow generator is compliant to
ISO8573-1:2010 Class 1.2.1, see highlighted data below.
