Time-of-flight mass spectrometry - Wikipedi

Tandem time-of-flight (TOF/TOF) is a tandem mass spectrometry method where two time-of-flight mass spectrometers are used consecutively. To record full spectrum of precursor (parent) ions TOF/TOF operates in MS mode. In this mode, the energy of the pulse laser is chosen slightly above the onset of MALDI for specific matrix in use to ensure the compromise between an ion yield for all the parent. Time of Flight is the process of measuring the distance to objects by measuring the time it takes for a signal sent by an observer to make the round trip from the observer to the object and back. I co-founded a ToF Company called Canesta acquired by Microsoft in 2010 (my wife came up with this name: CANesta = Cyrus-Abbas-Nazim the names of my cofounders).

  1. Time-of-Flight Mass Spectrometry Technical Overview Introduction Time-of-flight mass spectrometry (TOF MS) was developed in the late 1940's, but until the 1990's its popularity was limited. Recent improvements in TOF technology, including orthogonal acceleration, ion mirrors (reflectron), and high-speed electron
  2. In the animation above, the flight lasts a few seconds. In TOFWERK instrumentation, the flight is much faster: tens of thousands of flights per second, or flight times of about 10 µs to 100 µs. In cases where a spectral rate of 20'000 spectra/second is not required, multiple TOF extractions are accumulated into a single spectrum

  7. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI - TOF MS) is an emerging potential tool used for the identification and diagnosis of microorganisms. The use of MALDI - TOF MS is more as compared to other techniques because the process is rapid, has a high accuracy rate, and is economical in terms of cost and labor. MALDI - TOF MS can be used in broad areas like in the identification of bacteria, viruses, and certain fungal pathogens, strain typing.

Time-of-Flight. TOF mass spectrometry (TOF-MS) is a nonscanning technique whereby a full mass spectrum is acquired as a snapshot rather than by sweeping through a sequential series of m/z values while acquiring the data. It is described here as a snapshot because, although ions of different m/z arrive at the detector sequentially (low m/z first), the samples are loaded into the ion source with.

Matrix Assisted Laser Desorption Ionization — Time of Flight Mass Spectrometry (MALDI-TOF-MS) Die matrixunterstützte Laser-Desorptions-Ionisation mit Flugzeitmassenspektrometer-Detektion wurde als schnelle und empfindliche Absolutmethode zur Bestimmung von Molmassen großer Moleküle entwickelt Time-of-flight mass spectrometers (TOF MS) do exactly what their name suggests: determine an ion's mass-to-charge ratio (m/z) based on how long it takes for that ion to travel down the instrument's flight tube and reach the detector 6230B Time of Flight (TOF) LC/MS The Agilent 6230 time-of-flight LC/MS (LC/TOF) system allows you to upgrade from unit mass measurements to accurate mass for even more confident compound identification beyond conventional LC/MS detection Time of flight mass spectrometry (TOF-MS) is one approach to capturing a broad molecular weight range of signals associated with polar and nonpolar compounds in a single sample. This method uses an electric field to accelerate ions to the same potential. The ions advance to the detector through a flight tube where the time to reach the detector is related to the mass of the ion. Advantages of using TOF for broad spectrum analysis includes increased mass accuracy and mass resolution. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) has been successfully applied in recent years for first-line identification of pathogens in clinical microbiology because it is simple to use, rapid, and accurate and has economic benefits in hospital management. The range of clinical applications of MALDI-TOF MS for bacterial isolates is increasing constantly, from species identification to the two most promising applications in the near future.

Time-of-flight mass spectrometry utilizes a vacuum chamber. Ions are accelerated through the chamber by an electric field but once they enter the chamber there is no electric field and the ions move only by the kinetic energy obtained when they were originally accelerated Custom, modular Time-of-Flight MS Affordable TOF platform for academic research From low, to mid and high-resolution Positive or negative configuration available. ioniTOF Time-of-Flight Mass Spectrometers. IONICON is known for PTR-MS mass spectrometry since 1998. The first TOF based PTR-MS analyzer was launched in 2007 and soon became a huge success, predominately in the high-end academic. The type of a mass spectrometer most widely used with MALDI is the time-of-flight mass spectrometer (TOF), mainly due to its large mass range. The TOF measurement procedure is also ideally suited to the MALDI ionization process since the pulsed laser takes individual 'shots' rather than working in continuous operation Time-of-Flight MS - Detektor Abb. eines Time-of-Flight Massenspektrometers (links), angeschlossen an einen MASTER GC von DANI (rechts) Der DANI Master Time-of-Flight Massenspektrometer ist besonders für Applikationen, bei welchen die schnelle Identifikation von unbekannten Analyten der Probe benötigt wird, der ideale GC-Detektor

Functionality of Q-TOF MS

Background: Matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-TOF MS) has shown promise in decreasing time to identification of causative organisms compared to traditional methods; however, the utility of MALDI-TOF MS in a heterogeneous clinical setting is uncertain Using an equation, the amount of kinetic energy gained by the ion packet in the field can be converted into unidirectional velocity, time-of-flight (TOF). The TOF is proportional to the squareroot of m/z for a constant flight path and acceleration voltage Quadrupole Time-of-Flight (Q-TOF) MS By switching the last quadrupole mass analyzer in a TQ MS to a TOF mass analyzer, we will get the Q-TOF hybrid MS (Figure 24).

In addition, it can perform good quality quantitative analysis Cranial time-of-flight (TOF) MR angiogram performed at 3T using maximum intensity (MIP) and shaded surface display (SSD). TOF MRA is based on flow-related enhancement, which occurs when fully magnetized blood flows into a slab of magnetically saturated tissue whose signal has been suppressed by repetitive RF-pulses In contrast, time-of-flight (TOF) MS has higher mass resolution than quadrupole MS and allows for post-acquisition data interrogation of drugs and metabolites not originally specified in the experimental method. This latter process is not possible using triple quadrupole MRM data, which only records information on those species originally specified. This study was conducted to evaluate the.
