UdelaR use Precision to supply carrier gas to their GC

We recently spoke with Professor Eduardo Dellacassa of UdelaR about his use of Precision hydrogen generators in his GC analysis.

The University of the Republic (UdelaR) is a public research university in Montevideo, Uruguay. It is the country's oldest and largest university. Established in 1849, it has maintained a leading role in advancing academic research and higher education.

The University of the Republic is organized into 16 independent faculties. It oversees 7 university schools and scientific institutes, the Hospital Clinic Manuel Quintela, as well as three regional university centers that serve different parts of the country.

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

Plant secondary metabolism, food and beverages VOCs, and Cannabis VOCs, but not cannabinoids.

What PEAK Scientific generators do you have in your laboratory and what GC instruments do they supply?

We use a Precision Hydrogen 300cc for our Shimadzu GC 2010 Plus and Shimadzu GC-MS 2020.

Is your generator used for carrier gas, detector gas or both?

We only for carrier gas

Are you using a GC method(s) for your analysis? If yes, which method(s)?

Analysis of VOCs from complex matrices (food, beverages, essential oils) extracted by SDE, HS-SPME, SPE

What prompted you to choose a PEAK generator for GC and how long have you used it?

We selected the Precision hydrogen with information received from local representatives and have been using it for the last 6 years.

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

Eliminating the use of gas cylinders and the cost of helium.

Have you ever had a site visit from a PEAK engineer in relation to your generator for GC, if so, could you describe your experience of this support?

A PEAK technician visited us only once a year after we purchased the equipment. However, we continue to ask for help to avoid the presence of detectable water in GC-MS tunnings

Would you recommend PEAK Scientific generators to other laboratories? If yes, what would be your main reason for the recommendation?

I certainly would. In fact, many other PEAK generators and compressors have been acquired by our institution

Supporting your GC with Precision

PEAK’s Precision range of hydrogen gas generators has been a staple under many lab benches and has been the ideal method of moving away from bulk gas supply and the issues these can bring.

Eduardo mentioned not only eliminating the use of gas cylinders as a benefit of using PEAK generators but also combating the rising cost of helium. As well as rising costs of helium, many labs have to consider the frequent shortages of helium. In the last 5 years, we have seen 4 separate occasions where helium shortages have hit the headlines.

With an in-house hydrogen generator, these concerns are laid to rest as you can supply your GC with high-purity, high-quality, sustainable hydrogen from deionized water.

The new face of GC Gas Generation

Bringing convenience to your workflow by eliminating the risk of cylinder supply interruptions, the Intura series of hydrogen, nitrogen and zero air generators deliver a reliable, round-the-clock gas supply with a low lifetime cost, delivering tangible value to your lab.

Furthermore, Intura’s extremely low power consumption and heat output reduce operational carbon emission and the reduced weight of the generators aid in reducing carbon emissions from transportation, minimizing overall carbon emissions from lab operations - day in, day out.
