Agilent VOC 5975 GC-MS System with EST Encon Purge and Trap and Arcon Autosampler

Agilent Volatile Organic Compound 5975 GC-MS System with Purge and Trap and Autosampler

The hardware and software for the Agilent 5973 mainframe has been upgraded to a 5975 triple axis platform. The 5975 GC-MS System, paired with the EST Encon Purge and Trap concentrator and Arcon Autosampler, is a high-performance solution for VOC (volatile organic compound) analysis in drinking water, wastewater, soil, and environmental samples. This complete setup is designed to deliver industry-leading sensitivity, reliability, and automated sample handling for EPA and regulatory compliance methods.

Key Benefits:

• High Sensitivity & Accuracy – The Agilent 5975 GC-MS ensures precise VOC detection at low parts-per-billion levels, critical for environmental testing.
• Automated Workflow – The Arcon Autosampler streamlines sample loading, reducing hands-on time and increasing laboratory productivity.
• Efficient VOC Concentration – The EST Encon Purge and Trap system enhances analyte recovery, delivering superior performance for water and soil matrices.
• Regulatory Compliance – Optimized for U.S. EPA Methods 524.2, 624, and other environmental VOC protocols.
• Reliable & Proven Design – The Agilent 5975 platform is trusted worldwide for durability, reproducibility, and cost-effective operation.

This integrated GC-MS solution is ideal for environmental laboratories, water testing facilities, and research labs that demand accurate, compliant, and efficient VOC analysis.

Benefits of SIM Mode (Selected Ion Monitoring):

• Higher Sensitivity – Focuses only on selected ions, lowering background noise and improving detection limits.
• Quantitative Accuracy – Ideal for trace-level VOCs or targeted compounds that require precise quantitation.
• Better Signal-to-Noise Ratio – Cleaner data for compounds present at low concentrations.
• Regulatory Compliance – Used for EPA and other methods that demand ultra-low detection levels.

Benefits of Scan Mode:

• Broad Spectrum Analysis – Detects all ions over a set mass range, allowing for unknown compound identification.
• Qualitative Data – Provides full spectra for compound confirmation and library searches (e.g., NIST library).
• Flexibility – Useful in method development, troubleshooting, and non-targeted analysis.
• Archival Data – Captures complete mass spectra for retrospective analysis if new compounds of interest emerge.

Benefits of Combining SIM and Scan (SIM/Scan Mode):

• Best of Both Worlds – SIM offers sensitivity for target analytes, while Scan mode collects broader data for confirmation or unknowns.
• Efficiency – Run compliance methods (e.g., EPA 524.2, 624, 8260) with both quantitative accuracy and full-scan confirmation in a single analysis.
• Confidence in Results – Detects trace compounds with SIM while ensuring no unknown VOCs are missed in Scan.

In short:

1. SIM mode = sensitivity and quantitation,
2. Scan mode = identification and confirmation,
3. and SIM/Scan = comprehensive analysis.
