"I have used the LECO BT4D for the separation, identification, and quantification of anabolic steroids.

The advantages of the GC×GC system to separate stereoisomers in a complex matrix means time can be saved from doing complex sample preparation and extraction procedures. The ability to separate and quantify low levels of target analytes from high levels of matrix interferences has been key to my work. With LECO’s user-friendly ChromaTOF software, expert application scientists, and fantastic technical service team, LECO is a reliable and trusted research partner."

"In 2019 EPSRC funded our vision for a regional Centre of Excellence (CoE) in 2 dimensional gas chromatography and mass spectrometry. This Regional CoE, initially embracing the Universities of Bath, Portsmouth, Southampton, and Swansea, will significantly drive discovery, characterisation and quantification of new modalities, delivering a step change in capability for detection and identification of new species that cannot be separated and determined by 1D GC alone.

LECO’s Pegasus HRT 4D GC×GC-TOFMS and the benchtop BT4D GC×GC-TOFMS, both with extensive automated sample handling capability were delivered in late 2019 and early 2020. Installation of these state-of-the-art instruments was complicated by Covid-19 and lockdown 1.0. With such complex instrumentation, and application areas, effective training was key; here LECO took the initiative and provided both bespoke local and on-demand online training.

The level of service support and close collaborative relationship with LECO (applications team and account manager) has been first rate. Both systems can now be operated remotely, enabling high level users from across the South West region to access the instrumentation and allow many complex questions to be probed. Our work covers a vast array of application, e.g. petrochemical, environmental and metabolomics. The data sets are rich and complex, yet simplified by a user friendly software interface. Compared to 1D-GC, the 4D systems provide an astonishing number of additional analyte identifications, giving us deeper insight and understanding of the samples. Combining LECO’s high resolution mass spectrometry with comprehensive gas chromatography, multiple sample handling options such as SPME, Pyrolysis and TD along with full automation has created a world class laboratory of which we are all very proud."

"I have been working with LECO instruments for approx. ten years. I worked with the PEGASUS® 4D, TruTOF, GC-HRT and, for few days in Berlin, with the Pegasus BT and BT 4D – I really enjoyed that. There are several reasons why I like working with the devices and why I would not consider using other GC-MS insturments.

LECO instruments are reliable and robust with well working peak find and mass spectral deconvolution algorithms. In principle, LECO instruments are allowing both target and non target analysis which can be performed in one run, with nice sensitivity. Data processing is easy and everything is done in one SW – no need to use complicated combinations of SWs. LECO has an excellent customers support"

"Following years of service from the old LECO PEGASUS® 4D TOF GC-MS, we upgraded to a new LECO Pegasus BT4D TOF GC-MS. The decision was made due to the exceptional separating power afforded by thecryogenic modulation and the durability of the LECO StayClean® sourcetechnology which has been carried into the updated system. The combination of the two open up a wide variety of analyses to us whichenable use of this instrument in many aspects of our research."

"In 2013, I became responsible for overseeing the department’s analytical suite which included a LECO PEGASUS® 4D GC×GC TOF MS as our flagshipinstrument. I had no experience in gas chromatography and found even a standard GCMS daunting. Over the past years, I received extensive support from LECO. Especially withsupport from LECO UK the instrument is still running strong a decade after purchase. I anticipate it will go for another decade and then some."

"With the Pegasus BT 4D performing untargeted analysis today is very easy, thanks to the high sensitivity of the instrument, we are able to mine and analyze any type of sample! A combination of very good sensitivity, quality to price ratio and high flexibility make the Pegasus BT 4D system perfect for analysis of every sample"
