Thermo LTQ XL Linear Ion Trap Mass Spectrometer with Vacuum Pumps

***Unit was tested as far as we could. (Electron multiplier fail & noisy signal when tuning.) System will need to be validated/calibrated to ensure accurate results. Inquire if validation/calibration is available for an additional cost). Unit is preowned with slight wear from normal use. Buyer can expect everything pictured with 30-day warranty. See photos for details. 

 includes:

• LTQ XL Linear Ion Trap Mass Spectrometer
• Edwards E2M30  Rotary Vane Vacuum Pump (Qty: 2)

The LTQ XL ion trap MS extends the legendary MSⁿ performance of the LTQ ion trap, incorporating more techniques to generate structural information through innovations in Thermo Scientific ion trap technology.

• Unparalleled sensitivity and unmatched MSⁿ spectral quality
• Pulsed Q dissociation (PQD) for generating more fragments and extending the low mass range
• High-resolution isolation (HRI) enables isolation of isobaric mass peaks for cleaner MSⁿ spectra
• Ultra-fast polarity switching for high sensitivity analysis of unknowns
• Automated data-dependent neutral loss for PTM and biotransformation analyses
• Excellent charge state determinations with Ultra ZoomScan

The LTQ XL supplies outstanding sensitivity and abundant structural information for:

• Protein identification and quantitative differential expression analysis
• Biomarker studies and PTM identification
• Metabolite identification and quantification
• Tissue imaging
• High-speed LC methods

Obtain high sensitivity full scan MS along with in-depth MSⁿ (CRM) capabilities with the Thermo Scientific LTQ XL linear ion trap mass spectrometer. A single quadrupole offers Selected Ion Monitoring. A triple quadrupole adds Selected Reaction Monitoring. A linear ion trap goes further by enabling Consecutive Reaction Monitoring where a selected ion is fragmented into a product ion and the resulting product ion further fragmented in additional consecutive steps. Each additional fragmentation step makes compound identification more certain and facilitates structural characterization.

Manufacturer's Specifications:

The Edwards E2M30 Rotary Vane Vacuum Pump offers excellent ultimate pumping speed while providing quiet operation. With outstanding vapor handling capabilities, the E2M30 is a reliable and versatile 208V vacuum pump.

• Large, clearly marked, easily accessible controls
• Operate at quiet 48dBA
• Easy to use and service (require no special tools)
• Fast-acting inlet valve prevents oil and gas suck-back in the event of power or oil pressure loss
• NW25 inlet/outlet connections 

High vacuum or high throughput from the same pump

• Easily selectable modes
• High Vacuum mode provides ultimate vacuum down to 1.5 x 10^-3 torr with no gas ballast
• High Throughput mode sustains long-term high inlet pressures with ultimate vacuum as low as 2.3 x 10^-2 torr without gas ballast

Adjustable gas ballast control maximizes vapor handling capability

• Gas ballast delivered into pump prevents condensation of vapor carried by pumped gases
• Three user-selectable gas ballast positions—'0' Closed, 'I' Low Flow, 'II' High Flow—meet most vapor handling requirements.
