Launched last year, the Genius range of Gas Generators from Peak Scientific is world-renowned for being smoother, quieter, safer and more efficient than any other generator on the market. Today, the Genius range grew in strength with the addition of the NM-3G Nitrogen Generator.

The NM-3G Nitrogen Generator, designed specifically for use with LC/MS (Liquid Chromatography – Mass Spectrometry) instruments, offers safeguards unique to Peak Scientific generators to deliver reassurance and confidence for critical functionality. When designing the NM-3G, Peak Scientific’s engineers worked with leading LC/MS instrument manufacturers including Waters Corporation, Thermo Fisher Scientific, Agilent Technologies, Shimadzu and Bruker to build a nitrogen generator which would meet the approved flow rates, purities, pressure and, above all, reliability required by LC/MS applications.

The 3G range of generators benefits from improved compressor cycling for longer compressor life and new technology and programming. Crucially, a back-up compressor ensures continuous operation in the unlikely event of one compressor failing. This feature is totally unique to Peak Scientific’s 3G- range of generators, making the NM-3G the only nitrogen generator on the market with this level of reassurance designed for use with all LC/MS instruments.

“The back-up compressor fitted to the NM-3G makes it ideal for use in clinical applications. These generators are designed for situations where failure simply isn’t an option and confidence in the generator is essential.” – Chris Pugh, Engineering Director, Peak Scientific

The NM-3G utilises ‘membrane technology’ to generate nitrogen, separating gases via the principle of selective permeation across the nitrogen membrane wall. Fast gases permeate through the membrane wall more readily than slow gases, separating the original gas mixture into two streams. This allows the generator to isolate nitrogen from normal air, which is fed into the system via internal air compressors making it a standalone system which doesn’t require an external air source. The purity of the desired streams can be adjusted depending on operating conditions, with the system capable of delivering high-purity nitrogen at 30 L/min under normal operating conditions.

As with all Peak Scientific gas generators, the NM-3G comes with their world class after sales service as standard.

Peak Scientific’s Genius range of Nitrogen generators has officially added another string to its bow with the introduction of the Genius 1022 Nitrogen Generator. Based on the popular NM32LA model, the 1022 has been modified for unparalleled integration with Thermo Scientific’s Q Exactive™ Mass Spectrometers.

The Q Exactive™ is part of a new generation of Mass Spectrometers with a fast scan speed and multiplexing capabilities, allowing greater confidence in identifying and quantifying a wider range of compounds. The Genius 1022 Nitrogen Generator increases the operational pressure to meet the required input specifications of the Q Exactive™, ensuring a reliable and continuous flow of gas.

“Our Genius 1022 nitrogen generator has been specifically designed to support the higher input pressures demanded from instruments such as Thermo’s Q Exactive™ Mass Spec. Maintaining the balance of compressor cycling at a higher pressure to maximise operational service life, without compromising on the quality of gas delivered by the Peak Genius range.” – Chris Pugh, Engineering Director

The Q Exactive™ brings  a new level of sensitivity and performance at bench-top Mass Spectrometer prices, making it a perfect partner for Peak Scientific’s range of high-performance, ultra-quiet bench-top nitrogen generators. The new wave of bench-top mass spectrometry technology is expected to have a significant impact on several areas of research and basic analysis which require LC/MS including food safety, environmental analysis, drug metabolism and clinical research.

• Purity - Clean, dry carbon dioxide free air
• Durable - Few moving parts with minimum maintenance requirements
• Reassurance - Generator performs 24/7, if required
• Mobile - Flexibility to position generator where required, wall- mountable for small labs
• Quiet - Completely silent in operation
• Simple Installation - Generator only needs to be connected to the air source and application
• Economical - More cost effective than any other gas supply method
• Convenient - Gas on demand, no health hazards, no need to worry about running out of gas

Peak Scientific has been operating in South Africa now for two and a half years and has continued to grow steadily.

Due to the need for expansion Peak acquired this superb NEW building at the end of March 2011. Our new Peak Africa office is headed up by  business development manager; Dean Milbank to oversee operations with the support of our field service engineer Andy Von Arx, at hand to deliver exceptional service, training and support.

Our office based in Somerset West, 50km outside of Cape Town provides the ideal location for a stable base allowing much greater expansion of our services across the territory.

Pressure swing adsorption (PSA) is said to be the preferred choice for generating ultra-high-purity nitrogen.

The technology is self-regenerating, offering users a reliable and durable source of ultra-high-purity nitrogen with little need for attention.

The ANG range also provides a source of clean, dry air.

Peak systems are available with or without an internal air compressor.

The AG range of air and nitrogen generators is designed specifically for use with GC applications.

Models are available with different flow rates and can be used with multiple systems.

The generators offer ultra-high-purity nitrogen suitable for GC, ICP, DSC, TGA, TOD, TMA and DMA, plus clean, dry air from a single system.

This capability means one generator can cater for the requirements of multiple applications.

The generators are designed as plug-and-play systems, making installation simple.
