Case Study

Nitrogen Generation – Improving Purity of Nitrogen and Reducing Costs

Key Objectives

The Challenge

The university of St Andrews is Scotland’s first University and the third oldest in the English speaking world. The school of Physics and Astronomy is one of the UK’s leading departments that has an internatinally recognised set of research programmes

The School of Physics and Astronomy requires Nitrogen to purge to a suite of LCMS units used for compound analysis. Due to the sensitivity of the equipment that is supplied by the Nitrogen, it is essential to ensure a constant supply and a consistent gas quality. Traditional bottled Nitrogen was being used, however, the school of Physics & Astronomy wanted to have more control over their costs, wastage and improve on their environmental responsibilities.

The Solution

After our analysis and understanding of the customer’s strategy, requirements, and objectives, we recommended a Nitrogen generation system. This complete solution has a unique design and advanced energy saving technology. The university now has more control over their Nitrogen gas costs and are forecasting an annual saving of over £7000pa. We expect the department will have a return on their investment in 12 months with anticipated savings in excess of 70%. The gas purity is exceeding what they had hoped for and, additionally, they have reduced their carbon footprint as a result of this method of Nitrogen generation. This system will deliver huge savings over the lifetime of the generator.

The Result

“We are extremely happy with the N2 generator CPA supplied. The install went very smoothly and was completed within the time frame promised. The quality of Nitrogen is beyond what we could have hoped for with the ppm of 0.2 well exceeding our spec. As a result of this kit, we have been able to return some 40 bottles from the building with more still to go. I see this as a viable option to bottled gas, saving on rent, delivery and refilling charges.”
