GCMS-TQ RX Series - Features

• Supports Multiple Injection Modes and Enables More Efficient Method Development

  The Multi-Mode Injection Unit (MMI) supports a wide range of injection modes in a single unit, including split/splitless (SPL), programmable temperature vaporization (PTV), large-volume injection (LVI), direct injection, and thermal desorption/extraction (TD/TE). Dedicated software with an intuitive user interface enables easy method creation and seamless method transfer, simplifying analytical workflows.

•  

• Shimadzu’s proprietary thermal insulation technology achieves both high temperature stability and rapid heating and cooling. While maintaining excellent data compatibility with conventional split/splitless inlets, it also significantly reduces downtime for inlet maintenance, such as liner replacement.

• Off-Axis Ion Optics

  The Off-Axis ion optics eliminate neutral noise, such as metastable helium ions, without compromising sensitivity.

  New Low-Noise, Highly Robust Detector

  The GCMS-TQ8050 RX is equipped with a newly developed, patented detector that combines the latest noise-reduction technologies with high amplification performance. Combining this with Off-Axis ion optics creates a dual Off-Axis configuration that significantly reduces noise originating from neutral species. In addition, this new detector offers excellent robustness, ensuring stable and reliable long-term performance.

• A newly designed architecture reduces baseline noise to the lowest possible level, enabling highly reliable detection of peaks at lower concentration levels.

• 

• Increasing the distance between the filament and the ion source reduces the influence of the filament’s electric potential. In addition, a shield blocks radiant heat generated from the filament, helping to maintain a uniform ion source temperature. This prevents the formation of localized hot spots, resulting in higher analytical sensitivity. (Patent: US7939810)

• 

• A high-accuracy mass filter equipped with pre-rods, combined with patented electric field control technology, delivers excellent mass separation performance. In addition, the pre-rods minimize contamination of the quadrupole, eliminating the need for quadrupole maintenance.

• 

• The newly developed long-life filament delivers a service life more than five times longer than conventional filaments. By significantly reducing reanalysis and downtime caused by unexpected filament breakage, it supports stable and reliable operation.

• Flexible Method Development with Smart MRM+

  Smart MRM+ allows flexible adjustment of the data acquisition time window. Widening the window helps prevent missed detections, even for compounds with retention time shifts or peak tailing. Additionally, event times can be easily modified for each compound, and compounds can be added or removed with ease.

• Smart MRM+ enables the creation of simultaneous Scan/MRM methods. During quantitative MRM analysis, scan data can be used to assess matrix effects. The GCMS-TQ RX Series also delivers performance comparable to a single quad GC-MS, providing high-quality scan data even during simultaneous Scan/MRM analysis.

• Time Management for the Measurement Workflow　

  The operating status of each instrument in the laboratory and the estimated completion time of consecutive analyses can be monitored in real time. In addition, the remaining time until completion is displayed during instrument start-up and shutdown, which helps improve overall laboratory productivity and operational efficiency.

• Hydrogen or nitrogen, which are more cost-effective and readily available than helium, can be used as alternative carrier gases. With high-performance flow controller and a design that minimizes the influence of carrier gas properties, the GCMS-TQ RX Series ensures stable measurements with hydrogen or nitrogen carrier gas without requiring changes to the system configuration.

• 

• Hydrogen Carrier Gas

  Hydrogen is an effective alternative carrier gas in terms sensitivity and separation performance. By equipping the optional hydrogen sensor, the system automatically switches to a safe standby mode in the unlikely event of a leak, ensuring safe and reliable operation when using hydrogen as the carrier gas.

• Nitrogen Carrier Gas

  Even when employing nitrogen carrier gas, which has a relatively narrow optimal linear velocity range, the GCMS-TQ RX Series, by using constant linear velocity mode, achieves separation performance equivalent to that obtained with helium.

• The GCMS-TQ RX Series is equipped with an ecology mode that reduces power consumption and has been certified under Shimadzu’s environmental recognition program, Eco Products Plus. In addition to lowering running costs during analysis, it helps reduce CO₂ emissions, contributing to the realization of a decarbonized society.

  Reducing Environmentally Hazardous Waste

  An oil-free type roughing vacuum pump can be used, eliminating the need for regular oil replacement. This significantly reduces oil consumption and contributes to a lower environmental impact.

• 

• One-Touch GC Inlet Maintenance

  The system is equipped as standard with the ClickTek™ nut, which allows the GC inlet to be opened simply by turning the lever by hand—no tools required. This significantly reduces the workload associated with insert replacement and improves overall maintenance efficiency.

  Easy Start-Up and Shutdown Via a Touch Panel

  The vacuum system ON/OFF and Easy stop* can be directly operated from the control panel on the GC. This eliminates the need for a computer, enabling smoother maintenance of the GC inlet, column, and ion source.
  
  * Easy sTop is a function that enables septum and glass insert replacement at the GC inlet without stopping the vacuum system.

• By simultaneously connecting two different columns to the MS, application-specific data can be acquired without stopping the vacuum. Because no restrictor tubing is required, existing methods and retention times used with a single column can be applied without modification.

• Shorter Analysis Time　- Backflush System -

  The backflush system reverses the carrier gas flow after the target compounds are detected, expelling un-eluted components remaining in the column from the injection inlet side. This shortens analysis time and improves overall analytical productivity.

• 

• Multiple Chromatograms in a Single Run
  - Detector Splitting / Switching System -

  Detector splitting divides the column outlet and distributes a single flow path simultaneously to multiple detectors. This allows multiple chromatograms to be obtained from a single analysis, enabling efficient data collection while reducing cost and measurement time, leading to higher productivity.

• Multiple Chromatograms in a Single Run
  - Heart-Cut System -

  Heart-cutting is a separation technique that uses two different columns. Components that cannot be sufficiently separated on the first column are selectively transferred to a second column with different polarity for additional separation. Even with multiple heart-cut operations, peak retention times in downstream analysis remain unchanged, ensuring stable and reproducible separations.

• 

• Intuitive Software Interface

  Even in systems combining multiple columns and detectors, the visually intuitive software interface enables easy operation from method creation through analysis.
