Overview

The Thermo Scientific ISQ 7000 is a single quadrupole GC-MS system designed for high stability, sensitivity, and continuous operation in demanding analytical environments such as food safety, environmental monitoring, forensic toxicology, and regulatory compliance laboratories. It addresses challenges like evolving regulations, lower detection limits, increasing compound complexity, limited time, and cost pressures.

Key Features and Specifications

• High Sensitivity and Stability: The system achieves low detection limits by effectively reducing chemical, electronic, and neutral ion noise through advanced design features such as the S-shaped pre-quadrupole and patented RF lenses.
• ExtractaBrite Ion Source: Offers stable electron ionization (EI) and chemical ionization (CI) performance. It is fully removable under vacuum without venting, facilitating maintenance and ion source switching.
• NeverVent Technology: Enables routine maintenance tasks like ion source cleaning and GC column replacement without breaking vacuum or stopping the pump, reducing downtime by up to 98%.
• Dual Filament Design: Extends operational life with two filaments oriented identically for consistent performance and protected by electron lenses.
• Optimized Transfer Line: Ensures uniform heating along the chromatographic interface to prevent hot or cold spots, delivering ideal peak shapes even for high-boiling compounds.
• Triple Off-Axis Detection System: Incorporates a 10 kHz off-axis dynode, discrete electron multiplier, and high linear range electrometer for enhanced detection sensitivity and dynamic range.

Performance and Operational Advantages

• Continuous Operation: Designed for long-term consistent results with minimal maintenance interruptions, supporting high sample throughput.
• High Matrix Tolerance: The ion source and ion optics resist contamination, allowing over 400 matrix-rich samples (e.g., QuEChERS food extracts) without ion source maintenance.
• Vacuum Lock (VPI) and V-Lock: Facilitate ion source removal and GC column changes under vacuum, enhancing productivity.

Automation and Workflow Integration

• Modular GC System: The Thermo Scientific TRACE 1300 GC series features patented instant-connect inlet and detector modules, allowing quick module swaps (<5 minutes) without specialized service, supporting offline maintenance and maximizing uptime.
• AutoSIM and t-SIM Methods: Automated SIM ion selection from target lists imported from external files, enabling seamless method development and high-throughput targeted analysis.
• Chromeleon CDS Software: Provides comprehensive control of chromatography and mass spectrometry workflows with an intuitive interface, supporting over 350 modules from Thermo Fisher and other vendors. Features include integrated MS control, intelligent run control, and extensive reporting tools compliant with EPA regulations.
• SmartTune: Simplifies instrument tuning with guided workflows, customizable tuning targets, and automatic troubleshooting recommendations to ensure consistent performance.
• Environmental Analysis Extension Pack: Predefined templates and methods for rapid result calculation and EPA-compliant reporting, reducing setup errors and accelerating data review.

Sample Introduction and Ionization Options

• Direct Insertion Probe (DIP): Heated capillary for slow volatilization of solid or solid matrix trace components, ideal for forensic and tissue samples.
• Direct Exposure Probe (DEP): Rapid heating filament for liquid or solution samples, suitable for quick molecular weight confirmation of soluble or suspended solids.
• Chemical Ionization (CI): Soft ionization mode enhancing molecular ion generation and selectivity, especially effective for electronegative compounds such as halogens. Supports both positive and negative ion chemical ionization (NCI).

Automation and Sample Handling Solutions

• AI 1310 and AS 1310 Autosamplers: Designed for any sample throughput, these autosamplers improve GC result consistency and data quality with advanced features and ease of use.
• AS 1310 Gemini: Dual-channel autosampler for simultaneous injection, doubling sample throughput and productivity.
• TriPlus RSH Autosampler: Integrates with ISQ 7000 GC-MS for liquid, headspace, and solid-phase microextraction injections, with extended automation capabilities including sample preparation steps like dilution, internal standard addition, and derivatization. Clone Mode allows servicing two GC or GC-MS instruments with one autosampler platform.
• TriPlus 100LS: High-throughput liquid injection system compatible with TriPlus RSH accessories, offering scalable sample vial capacity and flexible injection volumes.
• TriPlus 300 Headspace Autosampler: Provides large sample capacity and incubation ovens for rapid volatile analysis with excellent sample integrity and traceability, seamlessly integrated with chromatography data systems.
