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.

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.

Once the adsorbent has reached its maximum saturation capacity, the cylinder goes through a depressurisation cycle resulting in near-vacuum conditions inside the cylinder. This results in the by-product gas molecules separating from the adsorbent so they can be flushed from the cylinder making it ready for further use. During the depressurisation cycle the cylinder cannot be used for further nitrogen generation making it unsuitable for applications where a continuous supply of nitrogen would be required.

To ensure the highest purity of nitrogen (up to 99.9995% nitrogen purity can be achieved with PSA Nitrogen generators) and enable continuous, uninterrupted nitrogen production, Pressure Swing Adsorption technology uses two identical Carbon Molecular Sieve columns which are alternately pressurized with compressed air.

When column 1 is pressurized, the non-nitrogen molecules are trapped in the porous carbon molecular sieve material and pure nitrogen travels through the column to be collected in a nitrogen receiver tank. At the same time, the second column is depressurized to atmospheric pressure to vent the trapped contaminant molecules from the column. Then the cycle continues by pressurizing column 2, while column 1 undergoes depressurization. Switching generation between cylinders in this way, with spent cylinders being cleaned whilst another is generating nitrogen, allows for a continuous flow of nitrogen from the generator.

The NM-3G Nitrogen Generator is designed specifically for use with any LC/MS instrument. This Premium model offers safeguards that are unique to Peak Scientific generators and effectively deliver reassurance and confidence for critical functions.

The Peak Scientific has been operating in 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.

Both the Management & staff of Peak Scientific Instruments Ltd were delighted to receive the Queen’s Award in 2004 & 2007. Accepting the award for the 3rd time Peak Scientific can only attribute the success to their strong international team, communication throughout the world by means of their exhibition team and strong client relationships through regular visits to the regions allowing increased awareness and knowledge of the products.

Peak Scientific pride themselves on service, this is shown through their dedicated team of support engineers, employed directly by Peak, based in key locations throughout the world. Their product knowledge and ability has ensured that they have beaten international competition to win business worldwide.

“Every week we have Engineers and Sales people travelling to every corner of the Globe spreading the news. This Award is recognition of their hard work and many weekends spent travelling away from home. Against the current economic climate it is a significant achievement.” - Robin MacGeachy, Managing Director of Peak Scientific

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 ANG 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.
