LCQ Classic LC/MS/MS Ion Trap, Thermo Fisher Scientific (CAT#: STEM-MSPO-0164-ZJF)

The manufacturer of the LCQ Classic LC/MS/MS Ion Trap, Thermo Fisher Scientific is Thermo Fisher Scientific.
Refurbished Thermo Finnigan LCQ Classic LC/MS/MS ion trap complete with the following: API Stack, ESI Probe, Edwards model E2M30 vacuum pump with hose, Pentium IV PC, monitor, keyboard, mouse, and new Finnigan Xcalibur 2.0 software with license.
The Thermo Finnigan LCQ classic is a quadrupole ion trap LC mass spectrometer equipped with electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI) ion sources, which can be interfaced to a Thermo Separation Products liquid chromatography (LC) system. Positive and negative ion ESI and APCI mass spectra can be acquired over the mass to charge range m/z 50 to m/z 2000 at unit resolution and with a peak width of 0.25 daltons/z. Acquisition of such spectra is important for protein/peptide sequencing because it permits identification of ions possessing up to 4 charges.
A specific ion may be selected, stored in the trap and collided with He gas in an attempt to have it undergo fragmentation reactions. The spectrum of the fragment ions resulting from such collisions can then be obtained. Also, one of these fragment ions can be selected, stored in the trap and induced to undergo collision-induced fragmentation. This process may be repeated up to 10 times. This MS/MS technique is important in structure determinations because ESI and APCI mass spectra are characterized by the presence of molecular and/or adduct ions (e.g., the molecular ion coordinated with one or more ubiquitous Na ions) and the absence of fragment ions that are often of diagnostic value in structure determination.
