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

We carry out Trace analysis of PFAS compounds in drinking water.

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

We have a Genius XE70 which supplies our 230V Agilent 6495C LCMS.

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

It was the proposed generator by the LCMS manufacturer, and it was bought 5 years ago.

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

The option of having N2 dewers was totally impractical and labor intensive.

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?

I give PEAK Scientific a rating of excellent in terms of service and responsiveness to our needs.

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

Yes, a month ago we had the PM service on our XE70. Michael was quick and done an excellent job. He spotted a small leak that could have caused a breakdown on the system. He was proactive and order the replacement part and made a second trip to replace it. Excellent work.

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

Yes, it is a great product and the service and support is great.

PEAK science starts at the source

With a PEAK Scientific service plan, you get more than just maintenance, you get peace of mind. Our team delivers quick, reliable support, with some areas offering 24-hour response and a 95% first-time fix rate which reduces delays and keeps your system operating at PEAK efficiency.

Service plans include dedicated PEAK parts, so replacements are ready when you need them, keeping your lab running efficiently and reliably. As mentioned above, when City of Tucson received a PM service on their Genius XE70, Francisco mentioned that our PEAK engineer worked quickly and did an excellent job as he spotted a small leak, proactively ordered the replacement part, and made a second trip to install it. His attention to detail prevented downtime and perfectly illustrates why regular servicing an part replacement is so important.

Our service plans also include visual support which allows our experts to remotely inspect your generator before visiting your lab, often identifying and solving issues before an engineer even steps on-site. This dynamic approach helps prevent problems, extend equipment life, and maximize your investment.
