What you are buying
A SCIEX 7500 QTRAP-ready triple quadrupole mass spectrometer paired with a Shimadzu LC-40 Nexera front end (LC-40D binary pump with built-in CBM-40 controller, CTO-40S column oven, SIL-40 autosampler, and DGU-40S degassing unit). The Shimadzu stack separates the mixture and delivers a reproducible gradient to the source. The SCIEX source converts the eluent into gas-phase ions. The triple quadrupole isolates a precursor, fragments it, and measures the product ion at trace levels.
Every unit moves through the GenTech Certified process. Solution Scientists disassemble and inspect each module, replace all consumables and degraded wear components, then tune and calibrate the instrument and verify performance against OEM and published benchmarks using known reference chemicals. The instrument ships with its verification report. A certified-refurbished system gives you that performance without the capital cost or the lead time of a new purchase.
What Sciex about this platform
The SCIEX 7500 system runs an OptiFlow Pro ion source with an integrated E Lens probe, built on the Turbo V ion source geometry. A D Jet ion guide concentrates ions while removing gas molecules and neutral ions ahead of the analyzer. The system shares the same rodsets as the QTRAP 6500+, with a dual-frequency RF drive across the triple quadrupole and a curved LINAC collision cell. Mass range covers m/z 5 to 2,000, with scan speed up to 20,000 Da per second. A high energy dynode paired with a pulse-counting detector switches polarity in 5 milliseconds, with a linear dynamic range up to 6 orders of magnitude. The system includes an upgrade path to QTRAP functionality, adding linear ion trap scans and MRM3 for additional selectivity, through a software license rather than new hardware. SCIEX OS software controls acquisition and data processing.
The LC-40D pump reaches up to 44 megapascals, or 440 bar, running isocratic, binary, or low-pressure gradient modes through a dual-piston design built to minimize pulsation. A CBM-40 system controller integrates directly into this configuration. The CTO-40S column oven runs forced-air circulation with electronic cooling, covering ambient minus 10 degrees Celsius up to 85 degrees Celsius, set in 1-degree steps, with temperature accuracy within 0.8 degrees Celsius and precision within 0.1 degrees Celsius; built-in dual leak sensors detect small mobile-phase leaks. The SIL-40 autosampler completes an injection cycle in as little as 7 seconds, with carryover held to 0.0025 percent or less without a rinse step, and can continue analysis across up to 44 microtiter plates using three plate changers. A DGU-40S degassing unit removes dissolved gas from the mobile phase ahead of the pump.
What each module does
LC-40D pump & CBM-40 controller
Delivers a reproducible gradient up to 44 MPa, with the system controller built directly into this pump configuration.
DGU-40S degasser
Removes dissolved gas from the mobile phase ahead of the pump, keeping bubbles out of the flow path.
SIL-40 autosampler
Draws a precise volume from a vial or microtiter plate and injects it onto the column, with a 7-second injection cycle and low carryover.
CTO-40S column oven
Holds the column at a set temperature from ambient minus 10°C to 85°C, with built-in leak sensors monitoring the compartment.
OptiFlow Pro ion source
Converts the liquid eluent into gas-phase ions, with a D Jet ion guide concentrating ions ahead of the analyzer.
Mass analyzer & detection
A triple quadrupole with a curved LINAC collision cell isolates a precursor, fragments it, and measures the product ion at trace levels, with QTRAP functionality available as an upgrade.

What “GenTech Certified” means
Refurbishment at GenTech is a defined process, not a wipe-down. Every system moves through the same five stages.
1. Disassembly and rebuild. Solution Scientists strip the instrument down, clean each module inside and out, and rebuild it from the frame up. They replace pump seals, pistons, and check valves to specification.
2. Configuration and new parts. Solution Scientists install the options and modules you selected and fit new wear parts throughout. They replace the detector lamp with a new one and reset the lamp hours.
3. Diagnostic and performance testing. Solution Scientists tune and calibrate the instrument, run system diagnostics, and confirm detector wavelength accuracy. They test full-system pressure and gradient performance against OEM and published benchmarks using known reference chemicals.
4. Data package you approve before shipment. The verification data goes to you for approval before the system leaves the bench. You see exactly how the instrument performs before it ships.
5. Delivery and installation. The instrument ships in protective packing with a one-year warranty option and professional installation available from a GenTech Solution Scientist.
Labs that run this system
The AB Sciex QTrap 7500 is method-compatible across the techniques most regulated and research labs run every day. These are the application areas buyers ask about most.
PFAS testing
EPA Method 537.1 and similar state programs require quantitation of per- and polyfluoroalkyl substances in drinking water at low parts-per-trillion levels, a sensitivity range triple quadrupole MS is built to reach.
Pesticides and mycotoxins
Multi-residue pesticide panels and mycotoxin screens in food and cannabis testing often cover more than 100 compounds in a single run, each requiring the selectivity a triple quadrupole provides against a complex matrix background.
Trace impurities and cleaning validation
Pharmaceutical cleaning validation protocols confirm that equipment surfaces carry no detectable residue of the previous product, often down to sub-part-per-billion swab or rinse limits.
Quantitative toxicology
Forensic and clinical toxicology panels quantify drugs and metabolites in blood, urine, or tissue against legally defensible limits, where a triple quadrupole’s selectivity rules out false positives from matrix interferences.
GLP-grade quantitation
Good Laboratory Practice studies require documented, audit-ready quantitation with full method validation, a standard regulated bioanalysis labs run routinely on triple quadrupole platforms.
