It's good to have a Genius in your lab

As the project coordinator of the Group of Bio-organic and Bioanalytics, Professor D. Oliveira-Silva, has been carrying out research for many years now. He focuses on various projects which require LC-MS analysis, such as target analyses in biological matrices, natural products determinations, proteomic and metabolomics analysis. He currently uses a Peak Genius NM32LA nitrogen gas generator which is coupled to his Bruker micrOTOF-QII system. 

Typically, what is the focus of your LCMS analysis - what sort of applications?

"I am the coordinator of the Group of Bio-organic and Bioanalytics and I am responsible for the MS Facility of UNIFESP - Campus Diadema. Several projects have been developed considering structure and mechanistic elucidation, target analyses in biological matrices, natural products determinations, proteomic, metabolomic and lipidomic analysis as well."

What Peak Scientific generators do you have in your laboratory and what LCMS instruments do they supply?

"We use an NM32LA nitrogen gas generator which is coupled to the HRMS Q-TOF system micrOTOF-QII from Bruker."

What prompted you to choose a Peak generator and how long have you used them?

"Peak Scientific is the leading gas generator supplier in Brazil and the brand of choice to couple to analytical devices such as GC and LC-MS systems. Besides the equipment's robustness and reliability the Brazilian team provide excellent support and prompt assistance. I have only compliments for them! In 2011 I had the opportunity to meet Mr. John Couttie (Global OEM Manager) during his visit to Brazil and he ensured me we would have no problems with Peak instruments. He was correct! So far, I have worked with NM32LA since 2010 and also used a Genius 1051 for two years (2012-2014) which was coupled to a triple-quadrupole LCMS-8050 (Shimadzu)."

What has been the key benefit of deploying Peak generators as opposed to your previous gas supply solution?

"Mostly cost reduction and ease of installation."

How would you describe your purchasing experience with Peak in terms of speed of response, ease of ordering, catering for your needs and timing of delivery?

"We purchase the equipment from a Peak partner (Shimadzu do Brasil), therefore I am not able to evaluate this issue."

Have you ever had a site visit from a Peak engineer, if so, could you describe your experience of this support?

"It was perfect! First of all it was readily booked. Second, a email information with a phone evaluation guided the diagnosis. The engineer arrived at our lab with all needed parts and the equipment got back at work in few hours. During the engineers visist he gave a lot of tips about how the equipment could work more properly and explained the importance of each component."

Would you recommend Peak Scientific generators to other laboratories - and if so, what would be your main reason for the recommendation?

"For sure, I recommend  Peak Scientific generators to any laboratory or analytical facility. My experience with Peak instruments and staff support my recommendation."


Peak’s Genius series of gas generators are compressor based systems designed for LC-MS analysis. They produce laboratory grade nitrogen and deliver greater efficiency, superior reliability and improved performance than other gas generators on the market today. Genius gas generators remove the requirement for an external source of air and replaces traditional methods of gas supply such as cylinders, dewars or bulk gas supply.

The Genius NM32LA uses tried and tested membrane technology and internal compressors to generate laboratory grade nitrogen on-site and on demand. They are built to last, with minimal maintenance requirements and designed for ease of use. Having a Genius in his lab, Professor D. Oliveira-Silva has increased his lab's efficiency and found the generator to be robust and reliable.  He has also been delighted with the aftersales support Peak have provided in the form of [Peak Protected] aftersales care. Peak’s aftersales support has not only kept his generator in peak condition but given the professor confidence in Peak’s products and its colleagues.
