Features of ITQ™ Series GC-Ion Trap MS Systems
External Ionization Ion Source
Standard on all ITQ systems with independently controlled heating from 125° to 300°C for stable operation and excellent chromatographic integrity * Enhanced spectral integrity when ionization takes place external to the trap, so the system stays cleaner, longer for improved uptime and longer periods between cleaning
Quadrupole Ion Trap Mass Analyzer * Unit mass resolution throughout the mass range * Durable inert materials for long life * Automatic gain control ensures that the ion trap is always filled with the optimum number of ions
Detection System * Digital electronic noise discrimination enhances sensitivity * Post-acceleration +10kV conversion dynode offers efficient positive and negative ion detection
Configurations Available for ITQ Series * Direct Sample Probe * Directly analyze solids or liquids without chromatographic separation and without moving the GC by using the Direct Sample Probe
Chemical Ionization * Optional chemical ionization increases selectivity and sensitivity * Both positive and negative chemical ionization modes supported; digital reagent gas flow control ensures method stability and reproducibility
Features Standard on the ITQ 1100 GC-Ion Trap MS; Optional for the ITQ 700 GC-Ion Trap MS; and ITQ 900 GC-Ion Trap MS * MSn with ACE and PQD * Capability to routinely test for compounds in the matrix that cannot typically be detected with other GC/MS techniques * Automated Collision Energy (ACE): Sutomatically calculates an estimated optimal collision energy based on product ion m/z and damping gas flow rates; runs at three energies across each scan * Pulsed Q Dissociation Mode (PQD): Generates information-rich mass spectral data, even in the low mass range; produces precise, reproducible fragmentation
Vacuum Probe Interlock * Restore system performance, change from EI to Cl or use the direct sample probe—all without venting the instrument using the Vacuum Probe Interlock
