Preface
About This Guide
This guide provides information on how to connect your LTQ Series mass spectrometer to
line power, the data system computer, the external vacuum system, and the waste exhaust
system. In addition, this guide provides information on how to connect external devices, both
those controlled from or independent of the Xcalibur data system.
The LTQ Series includes the following Thermo Scientific mass spectrometers:
• The LCQ™ Fleet™, a 3D ion trap mass spectrometer.
• The LXQ™, a 2D linear ion trap mass spectrometer.
• The LTQ™ XL, a 2D linear ion trap mass spectrometer. You can upgrade the LTQ XL
mass spectrometer to an LTQ XL/ETD system. The ETD module is physically coupled
to the back-end of the 2D ion trap. ETD enables peptide dissociation by transferring
electrons to positively charged peptides, leading to a rich ladder of sequence ions derived
from cleavage at the amide groups along the peptide backbone. Amino acid side chains
and important modifications such as phosphorylation are left intact.
• The LTQ XL MALDI system, an LTQ XL mass spectrometer pre-configured for
compatibility with the MALDI source. The optional API kit allows you to switch the
system to the ESI mode.
