QTRAP® 5500 LC-/MS/MS System by SCIEX

"It is excellent instrument to do the quantification analysis. It has good instrument hardware. It is easy to use and to maintain."

"Effectiveness of the product , High sensitivity and good MS resolution, enable high quality results, good reproducibility , easy to use, enable to high MS spray voltage, easy for conventional MS cleaning & decontamination."

"It is easy to use and good instrument hard ware. It gives good sensitivity and reproducibility. "

"Very good tools for environmental testing. Sensitive, robust, and easy to use. Service engineers are knowledgeable and helpful. Reasonable price. "

"For my work to identify biomarkers and metabolites quantification in low-level by LCMS the mass spectrometer of Sciex 5500 QTrap is very efficient in two aspects: scanning speed/mass analysis and high sensitivity in MRM mode. For some results using neutral loss (NL) mode, I also like the speed and sensitivity analysis when working with up to 2 NL transitions, no more than that. I have been working on the equipment about one year and I realize that the results are of high quality and reproducible results. Another advantage of the Sciex mass spectrometer is the ability to attach the equipment to a chromatograph of another company of my own preference. However, I have worked with others MS equipment software simpler, easy to learn and handle than the Analyst (the Sciex 5500 software). Further care to be taken when working with this equipment is to select the ion m/z desired with much attention because of its low resolution, although it is not a problem only assigned to this equipment. In relation to maintenance and cleaning is very practical equipment. The cost of maintenance, I believe to be the average of the other companies. Regarding the service after the sale, I have no objection, my questions are usually answered. "

"Software could be better, but like most software it is OK once you get used to it. We have had this instrument for 3 years and it has worked well consistently with no maintenance problems. It just keeps running, and I have confidence whenever I use it that it will perform well with no unexpected issues. Sciex service rep that performs yearly maintenance and calibration is knowledgeable and efficient, sales and application staff have been very helpful. "

"Hi-quality product to service our purpose and ease of use, high quality care service. "

"This instrument is easy to use, very stable with high resolution, low noise, and good MS accuracy and sensitivity. The source of MS instrument is very easy to maintain cleaning and very easy to clean up, too, by simply rising temperature to as high as 700°C. Sciex provides excellent service quality with very convenient and prompt tech support to help our customer to address the issues and solve the problems. The post-sale service is very satisfying. The instrument and service price is affordable and very reasonable. "

"QTRAP® 5500 LC-/MS/MS System was used to quantitate a targeted group of primary and secondary metabolites. MRM parameters were based on the results derived after manual infusion of each compound which once learnt was very easy. All the compound belonging to a group could be put together in a method and a single run on LC coupled to QTRAP 5500 can identify the compounds from the sample even if they have same retention time. The calibration curve can easily be made using multiquant software which requires standard at different concentration and thus getting results is extremely easy. Once the MRM has been made, all standards can be run in mixture thus saving time. The results are accurate as they are based on MRM. Thus the only time consuming step is making a MRM library for the standards. The cleaning is very easy and takes a little time as only the curtain gas plate requires cleaning only if machine is used regularly and the matrix is dirty. Moreover, can be used continuously without "

"The instrument meets our demand, offers low sensitivity and easy to use. Excellent service, better than other companies. Continued support in applications. The instrument is a little more expensive than other company but it's worth the money."

"It's an excellent product to use."

"This Product is very reliable and useful in the analysis of pesticides. It is also a very good product for Metabolite ID for Complicated metabolism studies especially soil. If you are doing residue or E-Fate Chemistry studies I highly recommend this instrument, although if you need more sensitivity the 6500 is a better option. "

"This is a value for money system, rugged, robust system with low downtime and has high resolution. We have a system in our lab and it has wider applications in pharmacy and biology."

"Improved linear trap sensitivity and speed over the 4000QT."

"The system has high selectivity, a short analysis time and is easy to prepare. It does not use a lot of materials and gives stable results."

"The system has excellent sensitivity. It would be better if it had a wider linear range- up to 100 should increase to 1000 orders of magnitude."

"Quite an efficient system for use in routine bionanalysis as in metabolites identification. Usable in both human and animal DMPK support in both a quantitation and qualitative manner."

"QTrap 5500 has an excellent performance overall. The service is excellent and the software is easy to use."

"reliable and robust."
