Chemlys Multi-stream Dimethyl sulfate (DMS) Analyzer: Excellence in Industrial Hygiene & Continuous Monitoring
Secure your production environments with our continuous monitoring analytical solution
The Critical Challenge of Dimethyl Sulfate (DMS) Detection
Dimethyl sulfate (DMS, CAS 77-78-1) is a highly toxic chemical compound, classified as a CMR (Carcinogenic, Mutagenic, Reprotoxic) substance, widely used as a methylating agent in the chemical and pharmaceutical industries. Faced with this invisible hazard, industrial hygiene regulations impose stringent Occupational Exposure Limits (OEL), often in the ultra-trace range of a few tens of ppb (parts per billion).To ensure absolute worker safety and flawless regulatory compliance, deploying a continuous ambient air monitoring system capable of detecting the slightest leak directly at the source is mandatory. To meet this technical challenge, Chemlys has developed a fully integrated, autonomous, and mobile analyzer cabinet.
The Chemlys solution: A Centralized Architecture to Optimize Your Costs
Safeguard your workforce and ensure regulatory compliance with our autonomous multi-channel analyzer: continuous ultra-trace detection to instantly mitigate exposure risks to highly toxic industrial gases.
To meet your most stringent regulatory compliance and worker protection requirements, Chemlys has engineered a state-of-the-art, fully autonomous multi-channel measurement system. Integrated into a wheeled mobile chassis, our analytical cabinet combines outstanding deployment flexibility with complete accessibility, streamlining all your maintenance operations.
Capable of sequentially monitoring the ambient air across your facilities—covering up to 16 distinct sampling points—it centralizes sampling, gas analysis, and alarm management to protect your teams without compromise.
How to detect 1 ppb Dimethyl Sulfate (DMS) leaks across multiple sampling points with a single centralized analyzer?
Optimize your monitoring costs while guaranteeing the absolute safety of your teams: the Chemlys analyzer centralizes cutting-edge detection technology within a single analytical cabinet.
Designed to meet the rigorous standards of industrial hygiene, this solution delivers four core strengths:
- Centralized multi-point monitoring
- Ultra-trace sensitivity (down to 1 ppb)
- On-demand stream prioritization by the user during alerts or suspect events
- Built-in system self-validation and continuous checking
Building on its deep expertise in gas analysis and complex sampling systems, CHEMLYS has designed a state-of-the-art monitoring solution tailored to the critical safety and performance demands of industrial facilities.
To meet strict regulatory compliance while addressing the critical needs for robustness, responsiveness, and cost optimization for industrial operators, our solution delivers major advantages:
- Centralized Multi-Stream Coverage (Up to 16 channels): The system connects and sequentially analyzes up to 16 distinct sampling points at distances up to 100 meters. This centralized architecture drastically reduces your capital expenditure (CAPEX) and maintenance costs by eliminating the need to deploy individual analyzers in every hazardous zone.
- Ultra-trace sensitivity: Engineered to stay ahead of the most stringent Occupational Exposure Limits (OEL), the system enables fine-tuning of detection thresholds, triggering preventive alarms at concentration levels below 1 ppb
. Built around the Industrial Gas Chromatography P5100, this solution combines the rugged stability of an industrial-grade GC with the flexibility and cutting-edge performance of a high-end laboratory analyzer. - Uninterrupted Service and Operational Agility: Selecting or disabling individual sampling streams is done with a single click on the user interface
. This dynamic, on-the-fly management occurs without ever interrupting the ongoing measurement cycle . - Built-in Self-Validation and Fail-Safe Security: The system features a permeation oven PermeaBOX dedicated to the verification channel
. Ce module génère une source de gaz de référence en continu pour tester l’appareil, garantissant ainsi son parfait état de fonctionnement quotidien et écartant tout risque de faux négatif .
