Laboratory nitrogen generator – for LC-MS and analytical applications

Nitrogen generator for laboratories – an efficient solution for nitrogen supply

A laboratory nitrogen generator enables the reliable on-site production of high-purity nitrogen for analytical applications. In LC-MS (liquid chromatography/mass spectrometry) in particular, a constant gas supply is crucial for precise and reproducible results.

Dürr Technik offers laboratory nitrogen generators with a purity of up to 99.5% – customised to your requirements, with or without an integrated compressor.

Which nitrogen generator is right for your laboratory?

With compressor (HF30A / HF30P)
→ if no compressed air supply is available

Without compressor (HF30N series)
→ where a compressed air supply is available

Without compressor (MG variants)
→ where a compressed air source is available
→ if dry air (source & exhaust) is also required
→ optimised for Sciex, Bruker and Shimadzu

Additionally:
Not every application requires the highest purity. For many analytical methods, 99.5% is sufficient – this significantly reduces capital and operating costs.

Previously the manufacturer led service was not meeting the expectation of our NHS laboratory, so we switched to Chromalytic around 6 years ago. During that time the Chromalytic engineers have serviced and maintained our 2 GCMS analysers and additional laboratory instruments to a high standard. We have also had a new GCMS Installed by the manufacturer and one decommissioned during which time the service contract with has been seamless. Chromalytic have recently assisted us with our laboratory move with patience and flexibility. We have been extremely happy with the responsive and knowledgeable service provided by Chromalytic at the end of the phone, by email and in person whenever we have asked for help and advice. Chromalytic is an all-round great service provider.

We approached Chromalytic to replace our nitrogen generators for LC-MS sample preparation. Phil (Chromalytic) understood our requirements and discussed a number of different options with us. There was clear communication throughout the process and delivery was prompt and efficient. The engineers did a fantastic job of replacing the existing supply lines, which had been cobbled together as the need for nitrogen for additional equipment had increased over time, with new lines and shut-off valves for each piece of equipment. The changeover to the new generators went smoothly and now ensures a continuous and reliable supply of nitrogen.

Chromalytic has been our annual maintenance service provider for our GC-MS and generators for more than 6 years. We like to renew our service contract every year as we have a very good customer service with very competent and friendly technicians and a qualified sales/service team. Chromalytic has always been very responsive and helpful when we have approached them, willing to discuss options and, as our business grows, to accommodate our changing requirements. We also recently purchased a Chromalytic ZA2A zero air generator with integrated compressor. We are very impressed with the generator, its value for money and the time and support that the Chromalytic engineers have invested to ensure that the generator integrates perfectly with our other laboratory equipment. The work went beyond the initial installation to adapt the generator, compressor and housing to our requirements. Based on our experience, I would highly recommend Chromalytic's generators and maintenance service to other laboratories.

Ms. Berry, Quality/Fragrance Compliance Manager, ROBERTET Group

We have enjoyed a very good working relationship with Chromalytic for over a decade. Chromalytic's services are essential for maintaining compliant scientific equipment. We have found Chromalytic's staff to be knowledgeable, reliable, very helpful and provide good value for money in carrying out the annual maintenance and qualification of our analyzers. There were instances where Chromalytic went far beyond what we expected. We can highly recommend their services.

To expand our range of in vitro ADME services to include hepatocyte stability assessments and permeability studies, we have invested in a highly sensitive triple quadrupole mass spectrometer. We have also purchased a new HF30A generator from Chromalytic to provide a continuous supply of high quality nitrogen to this instrument. The recent investment in in-house nitrogen production ensures a continuous and stable supply of nitrogen, which is crucial as pressure drops in the supply would cause instrument errors and interrupt the analysis. We are very pleased with the quality of the HF30A and the first class support Chromalytic provides us with.

We would like to take this opportunity to express our satisfaction with Chromqalytic’s gas generators and Dürr Technik’s oil-free compressors – equipment which we have had the privilege of installing, maintaining and evaluating in analytical and laboratory settings over the course of several years. As a company specialising in the technical servicing and maintenance of analytical equipment, we regularly work with equipment from the market’s leading gas generator brands. This experience has enabled us to directly compare different designs and technologies. In our opinion, Chromalytic’s gas generators are characterised by their outstanding build quality, operational reliability and design focused on ease of maintenance. Compared with other alternatives available on the market, we have observed high operational stability, a lower failure rate and a significant reduction in maintenance costs. Similarly, Dürr Technik’s oil-free compressors have proven to be a robust and durable solution. Their oil-free design eliminates the risk of contamination, significantly reduces maintenance requirements and ensures reliable operation even during continuous use. In our experience, these compressors have a longer service life and lower long-term operating costs compared to many similar systems we have serviced. For all these reasons, we believe that the solutions offered by Chromalytic and Dürr Technik are currently among the best options for laboratories, research centres and industrial plants that require a reliable supply of high-purity gases at low operating and maintenance costs. We would be happy to provide you with further information regarding our technical and operational experience with these systems.
