Quadrupole spectrometer GCMS-TQ RX series

MS/MStandemfor the food industry

Overview
The GCMS-TQ RX Series is a triple quadrupole gas chromatograph–mass spectrometer platform designed for routine high-throughput laboratories. Based on the 3R concept (Reliable, Resilient, Responsible), the system combines a multipurpose injection unit, flexible carrier gas compatibility and high-speed MRM capabilities to support evolving methods and diverse sample matrices.

Key benefits

• Adaptable platform supporting MRM, SIM and Scan acquisition modes on a single instrument.
• Multi-Mode Injection Unit (MMI) enables SPL, PTV, LVI, direct injection and TD/TE without hardware changes.
• Flexible carrier gas options (helium, hydrogen, nitrogen) and carrier gas saver reduce supply risk and operating costs.

Flexibility and Multi-Mode Injection (MMI)

• MMI supports multiple injection techniques in one unit, simplifying method development and transfer across workflows.
• Dedicated software functions streamline configuration for PTV, large-volume and thermal desorption applications.
• MMI thermal desorption heating rates up to 1200 °C/min for rapid TD workflows.

Ion source and ionization options

• Boosted-efficiency ion source with optimized electron beam focus for high ionization efficiency and low-level detection capability.
• Smart EI/CI mode acquires CI data without source change while maintaining EI sensitivity for combined qualitative information.
• Solvent-Mediated Chemical Ionization (SMCI) option uses methanol for CI to reduce reliance on flammable gases and simplify operation.

Detection, optics and performance

• Off-Axis ion optics reduce neutral noise while preserving sensitivity.
• New low-noise, high-amplification detector and dual Off-Axis configuration on selected models for stable long-term performance.
• Quadrupole with pre-rods and electric field control reduces contamination and maintenance frequency.
• Long-life filament design extends service intervals versus conventional filaments.

High-throughput capability
The UFsweeper collision-cell technology accelerates ion removal and improves CID efficiency, enabling many transitions at high speed for simultaneous multicomponent MRM analyses. The platform delivers Scan, SIM and MRM data comparable to single-quadrupole GC-MS systems while supporting high-speed quantitative workflows.

Software and data processing

• LabSolutions GCMS integrates acquisition and data review for efficient GC and MS workflows.
• Smart MRM+ enables flexible retention time windows and event timing to reduce missed detections and supports simultaneous Scan/MRM acquisition.
• LabSolutions Insight and Peakintelligence provide combined targeted and non-target workflows with AI-assisted peak integration to speed data processing.

Sustainable operation

• Carrier gas saver and optional gas selector reduce helium consumption by switching to nitrogen during standby.
• Support for hydrogen and nitrogen as alternative carrier gases with high-performance flow control and optional hydrogen sensor for safe operation.
• Ecology mode and compatibility with oil-free roughing pumps reduce energy use and hazardous waste.

Maintenance and usability

• ClickTek nut enables one-touch GC inlet access without tools for fast liner replacement and maintenance.
• Touch-panel vacuum control and Easy sTop allow inlet service without full system shutdown.
• Twin Line MS system supports two-column connection for application-specific acquisition without stopping the vacuum.
• Advanced flow features (backflush, detector splitting/switching, heart-cut) accelerate analysis and enable selective transfers between columns.

Application highlights
Validated methods and application notes cover pesticide residue analysis with MMI, volatile PFAS analysis, and high-throughput multicomponent MRM workflows, demonstrating suitability for environmental, food and routine testing laboratories.
