I started working with the PEGASUS GC-HRT⁺ 4D back in my student years. As a novice researcher, with no experience working with similar devices and no training, it was not easy at first. However, after years of working with this instrument and when compared with other sophisticated equipment in the field of gas chromatography - high-resolution mass spectrometry, I can confidently say that the ChromaTOF is the most user-friendly software of all those available now. Such a variety of functions, as well as very clear, convenient, and fast operation, combined with high-tech equipment, allows to get very decent results.

Over the past 5 years of using the Pegasus GC-HRT⁺ 4D, we have been able to conduct many various environmental studies, identifying trace amounts of substances in the cleanest Arctic environmental objects. At the same time, such a powerful combination of two-dimensional gas chromatography with time-of-flight mass spectrometry made it possible to analyze complex matrices, namely peat combustion products, herbal and tobacco cigarette smoke, petroleum and much more.

It is worth noting the work of the support service, which helped us very quickly and efficiently. I would like to thank the engineers for their work, who were on call almost 24/7. There are still many projects and tasks ahead that will undoubtedly be solved with the help of the Pegasus GC-HRT⁺ 4D.
