Module multiplexer

Modbusmulti-channel

Multiplexer
Modular multiplexers for selection of multichannel samples, adapted to site configuration and controlled by VISTACHROM software for centralized operation and traceability.

• VISTACHROM can:
• Execute cycle methods to analyze different ranges on each stream.
• Transfer per‑stream data via MODBUS.

Heated Multiplexing System with Inbuilt Calibration
Heated Multi Streams Selector
The Heated Multi Streams Selector is a multiplexing solution designed for automated sampling from multiple locations (up to 16 sampling points). It includes an inbuilt calibration module to ensure repeatable, traceable sampling and instrument validation.

Key Features:

• Advanced sampling design:
• Heated sample lines and valves to prevent condensation and loss of target compounds.
• Purging of inactive lines to reduce cross‑contamination and shorten transition times.
• Flexible calibration options:
• Multipoint calibration using permeation tubes (e.g., butane, hexane, benzene).
• Integration with certified gas cylinders for cross‑checks.
• Controlled dilution using nitrogen or zero‑air sources.
• Software integration:
• VISTACHROM® provides remote control, full traceability and exportable logs.
• Displays concentration trends per stream and per component.
• Configurable and application‑oriented:
• Configurable for VOCs, sulfur compounds and other target analytes.
• Operable in automatic or manual mode; supports up to 16 sampling streams.

Applications:

• Multi‑stream ambient and emissions air monitoring at industrial sites.
• Contaminant analysis for VOC and sulfur detection systems.
• Calibration, validation and performance checks of gas sampling networks.

Ordering Information:

• Model: XXX055

Purge and Trap
Simplified headspace sampling and purge‑and‑trap module for representative extraction from liquid phases. Vaporized samples can be preconcentrated on a trap to reach quantification levels in the ppb/ppm range, then injected automatically and continuously into an auto‑GC analyser.
