2015-04-23 Urine metabolic profiling combined with LC/QTOF-MS was used to find and identify the metabolites of dextromethorphan, a common over-the-counter (OTC) cough suppressant [17].Chromatograms of both blank urine and urine taken 4 h after ingestion of dextromethorphan were compared using Mass Profiler software.The software first analyzes all groups of ions (known as features) in the chromatogram of **AS-IS, Untested, due to price / age.** Waters QTOF Premier Mass Spectrometer. System Includes: Waters QTOF Premier MS Computer Cables and connectors. The Waters QTOF Premier Mass Spectrometer is the next generation exact mass platform for the Pharmaceutical, Biotechnology and Life Science industries. Quadrupole-time-of-flight (QTOF) mass spectrometers are high mass accuracy and high resolution instruments ideal for peptide sequencing in the Information Dependent Acquisition (IDA) mode. Their high resolution is useful for determination of charge state and protein mass measurements in addition to accurate mass determination of biological compounds. The price difference between Exactive+ and QExactive+ is around $10K, which is less then 5% of the instrument price. The largest detection mass range is 20 - 10000 Da. But the price of this kind of MS is very high.

Therefore, this study aims to investigate the protective effects of hydrogen on stroke-induced ischemia–reperfusion injury History of LC-MS. The coupling of chromatography with MS is a well developed chemical analysis strategy dating back from the 1950s. Gas chromatography (GC)–MS was originally introduced in 1952, when A. T. James and A. J. P. Martin were trying to develop tandem separation - mass analysis techniques. Agilent LC-MS QTOF. II.

The X500B QTOF System is purpose built for standard biotherapeutic characterization analyses while the X500R QTOF System offers robust qualitative and quantitative performance for food, environmental, and forensic workflows, or for metabolomic analysis. The impact II sets a technology standard for analytical performance in residue and contamination screening, forensics, industrial and synthetic chemistry, biomarker research, and more, with unparalled ultra-high resolution Qq-Time-Of-Flight mass spectrometry. Advances in Q-TOF LC/MS for Pharma Applications Figure 1:This analysis of a trace metabolite that co-elutes with the parent drug shows that next-generation Q-TOF LC/MS systems easily achieve a dynamic range of greater than five orders of magnitude. The figure shows a single spectrum from data obtained at 3.3 spectra per second.

Agilent’s GC-qTOF has a list price of about $375,000, Sheehan says, which is four-to-five times more than a single-quad system. But think also about application, he says. What kind of samples will you be working with, for instance? The LC system was connected to a Bruker Daltonics, maXis qTOF mass spectrometer equipped with an electrospray ion source operated in positive ion mode (Bruker Daltonics, Bremen, Germany).

A rapid, precise and accurate gradient UPLC method was developed for the selective separation of degradation products of alcaftadine. Forced degradation studies of the drug were carried out by examining factors suggested by ICH guidelines. The degradation products were formed in acidic, alkaline and peroxide conditions; however, the drug was stable in neutral, thermal and photolytic Categories: GC-TOF and GC-QTOF Home » Products » Mass Spectrometry » GC-TOF and GC-QTOF Time-of-flight mass spectrometers designed to achieve the best sensitivity and productivity, making qualitative and quantitative analyzes possible and easy to perform As a reductive gas, hydrogen plays an antioxidant role by selectively scavenging oxygen free radicals. It has been reported that hydrogen has protective effects against nerve damage caused by ischemia–reperfusion in stroke, but the specific mechanism is still unclear.
