mass spectrometry

A method for identifying molecules based on the detection of the mass-to-charge ratio of ions generated from the molecule by vaporisation and electron bombardment. Deflection of the ions through a magnetic field results in a characteristic pattern which is used to define the molecule of interest.

GC and RP-UHPLC coupled to a high resolution QTOF mass analyzer are powerful analytical platforms for a quick structure determination of isoquinoline alkaloids, previously to the application of other spectroscopic tools.
T-Wave mode utilizes a stacked-ring ion guide design that allows it to produce a traveling wave that accelerates ions into the second quadrupole mass analyzer. This has the effect of significantly improving the fast scanning abilities of a tandem MS.

These high-powered magnets are required in FF-MS in order to induce ions to oscillate within the mass analyzer, where their molecular weights can be measured.
In 2005, it launched the LTQ Orbitrap Hybrid MS (see IBO 6/15/05), which introduced a new mass analyzer to the marketplace to compete with Q-TOF MS.
