Multiple quadrupoles, hybrids and variationsA linear series of three quadrupoles is known as a triple quadrupole mass spectrometer. The first (Q1) and third (Q3) quadrupoles act as mass filters, and the middle (q2) quadrupole is employed as a collision cell… See more
ApplicationsThese mass spectrometers excel at applications where particular ions of interest are being studied because they can stay tuned on a single ion for extended periods of time. One place where this is useful is in … See more
Types of MS/MS systems and their key characteristics
Triple Quadrupole (TQ) MS. The simplest and most common MS/ MS system is the TQMS. It consists of three quadrupoles arranged in series with the first and third quadrupole acting as MS1 and MS2 respectively and the CID taking place …
