"Compared to GC equipped with a single column, the Pegasus 4D enabled me to separate unbelievable number of analytes! Tens of thousands of separated peaks in one run was not an exception. But where the separation was not perfect, ChromaTOF software and its deconvolution algorithm did the job. Such excellent ‘separating power’ helped me discover new types of plant PCB metabolites."
"We send instruments into the harshest of environments and run very demandingsamples on them. Bearing this in mind, our decision to upgrade the GC-MS at our remote Cape-Verde site to the new LECO PEGASUS® BT was driven by the promise of the StayClean® source. This minimizes down time and eliminates operations which are difficult to carry out when working with remote systems. The increased sensitivity of theinstrument enables us to take smaller sample volumes which again assists with easing the burden placedon the analytical machine. Finally! the upgrade from quadrupole to time of flight mass spec will enable us to keep historical datasets which can be interrogated for any compounds which prove interesting in the future."
"In 2013, I became responsible for overseeing the department’s analytical suitewhich 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."
"In the past, my company, CALCINOR S.A. used to carry out quality control tasks using muffle furnaces to determine Loss by Calcination.
When we acquired the LECO equipment to automate our process, we saw a significant improvement.
Our work with these instruments is very satisfactory and I emphasize the robustness of our LECO instruments because they are prepared for continuous work backed by LECO technical service. We continue to trust the LECO brand, acquiring their instruments when necessary."
AMG Superalloys UK Ltd
"AMG Analytical has been working on LECO machines for over 25 years for the determination of O, N, C and S.
We embarked on a project working with LECO to bring Hydrogen testing in-house. The outcome of the project was excellent!
We have now purchased a LECO ONH836 machine and will offer the testing of Hydrogen to its external customers.
In our experience the level of commitment, technical expertise and support provided by LECO is unique within the industry.
We have no hesitation in recommending LECO to any company wishing to improve the efficiency of their operations."
"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."
