Sampling

Sample introduction systems

Multiplexer

We propose multiplexers (selection of multichannel samples) adapted to your installation and controlled by our software VISTACHROM.

VISTACHROM can :

• “Cycle” methods to analyze different ranges on each stream.
• Transfer data via MODBUS, specific for each stream.

Heated Multiplexing System with Inbuilt Calibration

Heated Multi Streams Selector

The Heated Multi Streams Selector is a high-performance multiplexing system designed for automated sampling from multiple locations (up to 16 sampling points). This system is equipped with an inbuilt calibration module, ensuring reliable and precise measurements across a range of applications.

Key Features:

• Advanced Sampling Technology:
• Heated lines and valves to maintain sample integrity by preventing condensation and molecule loss.
• Purging of non-active lines for faster sampling and contamination avoidance.
• Flexible Calibration Options:
• Multipoint calibration using permeation tubes (e.g., Butane, Hexane, Benzene).
• Integration with certified gas cylinders for cross-validation.
• Controlled dilution using nitrogen or zero air generators.
• User-Friendly Software Integration:
• VISTACHROM® software provides remote control, full traceability, and export options for efficient data management.
• Displays concentration trends per stream and component.
• Reliable and Customizable:
• Configurable for VOCs, sulfur compounds, and other specialized applications.
• Supports up to 16 sampling streams with automatic or manual mode selection.

Applications:

• Multi-stream air monitoring for industrial sites.
• Contaminant analysis in VOC and sulfur detection systems.
• Calibration and validation of gas sampling networks.

Ordering Information:

• Model: XXX055

Purge and Trap

Simplified and enhanced headspace sampling system designed to extract representative samples from the liquid phase.

The vaporized sample can be preconcentrated using a trap to achieve quantification at very low concentration levels (ppb and/or ppm). Then, it is injected automatically and in continuous mode into the auto-GC analyzer.
