Thermo Scientific ConFlo IV Universal Continuous Flow Interface

Thermo Scientific™ ConFlo IV Universal Continuous Flow Interface is a versatile continuous flow interface designed to significantly expand the application range of stable isotope laboratories using isotope ratio mass spectrometry (IRMS). The ConFlo IV system enables seamless connection of multiple sample preparation devices, delivering fully automated, stable, and highly reproducible measurements.

The system features intelligent management of all required reference gases, automatic sample-size recognition, precise matching of sample and reference signals, and advanced self-diagnostics. These capabilities reduce operator involvement, lower operating costs, and increase overall laboratory throughput.

Key features

• Management of multiple devices
  Automated switching between different sample preparation units, including activation, deactivation, and reference gas changes, maximizes IRMS utilization.
• Continuous, unattended operation
  Application switching can occur at any time without operator intervention; preparation devices can be regenerated and reloaded while other analyses are running.
• Maximized performance and efficiency
  Using reference gases instead of bulk reference materials reduces operating costs by nearly 50 % while increasing sample throughput by almost 50 %.
• Enhanced accuracy and stability
  Automatic adjustment of reference gas pulse intensities equalizes conditions between sample and reference gases, improving precision and long-term reliability.
• Advanced data quality control
  Critical system parameters affecting data quality are automatically monitored across all sample sequences.
• Single-interface control
  All connected preparation and inlet devices are controlled through one interface, with the ability to add new samples or entirely new applications without interrupting ongoing data acquisition.
