Liquid chromatography–mass spectrometry (LC–MS) is an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography (or HPLC) with the mass analysis capabilities of mass spectrometry (MS). Coupled chromatography - MS systems are popular in chemical analysis because the individual capabilities of each technique are enhanced synergistically.

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 TOF-MS is helpful in the structure elucidation and identification of fragmentation patterns of the compounds. This review provides the brief introduction and applications of UHPLC/Q-TOF-MS with examples of some of the most advanced work in the pharmaceutical analysis. The largest detection mass range is 20 - 10000 Da. But the price of this kind of MS is very high. The last technique is a hybrid mass spectrometer, Q-TOF MS, which combines a single quadrupole MS and a TOF MS. Using this MS, we can get high resolution chromatograph and we also can use the MS-MS system to identify the target molecules.

四极杆质谱仪，qmsqms是最常见的质谱仪器，定量能力突出，在gc-ms中qms占绝大多数。优点：结构简单、成本低、维护简单sim功能的定量能力强，是多数检测标准中采用的仪器设备。 In MS/MS mode, it is 1,500:1 RMS. Mass resolving power is greater than 45,000 full width at half maximum (FWHM) at m/z 2,722. Mass accuracy in MS mode is less than 0.8 ppm RMS as measured from 10 repeat injections; in MS/MS mode, it is less than 2 ppm RMS on m/z 397 from the same measurement. 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.

Our high-quality, intuitive mass spectrometers empower all fields of research and development, setting new standards in performance. 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.

Your Q-TOF MS is missing some really important capabilities that a Q Exactive Orbitrap MS has. Things like screening and accurately quantitating simultaneously, staying calibrated over days…even weeks, and seeing significantly more components in your samples.

The instrument is capable of MS and MS/MS and it is using MassHunter software for data acquisition and processing. LC pumps can handle up to 8000 psi. Mass Accuracy of better than Abstract Background Isodon lophanthoides, I. lophanthoides var. graciliflorus and I. serra are the three botanical sources of Xihuangcao, which are often used indiscriminately in herbal products. The aim of this study was to develop a rapid and accurate analytical method to identify the three different botanical sources of Xihuangcao by combining UPLC-ESI-QTOF-MS with chemometrics analysis Brachychiton acerifolius, or Sterculia acerifolia as formerly known, is a member of a genus reported for a myriad of bioactive compounds.

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.
