Thermo Scientific™ Orbitrap Velos Pro hybrid MS by Thermo Fisher Scientific

"Very robust, high performance mass spectrometry equipment. Best system for protein identification and relative quantitative."

"It has amazingly high spectral resolution and mass accuracy. Allows the determination of intact mass for proteins even with 150kDa molecular weight via spectral deconvolution. For smaller proteins (molecular weight less than 35-40 kDa) monoisotopic resolution can be obtained, allowing quantitation of isoforms based on their relative intensities. It is relatively expensive, but it's worth the investment as one can obtain such results as never ever before. Ever since we have bought the instrument it has helped to solve many of our previous analytical problems. Coupled to ultra high performance liquid chromatography (especially comprehensive 2D-UPLC as in our laboratory) it can further enhance the usability. When one has such an expensive investment it is crucial to get the most information possible. We have carefully chosen the best instrumentation to meet our needs."

"We have had great experience so far with Orbitrap Velos Pro. It is stable and sensitive."

"High sensitivity and high selectivity allows detection of unknown materials. Easy to use, easy operation manual and automatic sequence. High maintenance fee for minor problems."

"An easy way to detect peptides in electropohoresis. A very useful tool in proteomics. Has good stability and reproducibility."

"Very easy to use, a perfect mass spectrometer for protein analysis. A high accuracy instrument for analysing complex protein samples. The after sales service is very good."

"The Orbitrap Velos is far one of the fastest mass spectrometers and is able to be coupled to capillary electrophoresis. Calibration is not hard but still takes a while and has to be done every two weeks. Electronic board burnt down twice in our first year's use."

"Very reliable and very easy to use. Customer service is great always available to assist to our needs."

"Best in class resolution >50,000. Good mass range, looks at a broad range of molecule types. Great problem solving tool and support for LC method development."
