Air Quality Analyzers: VOC, NMHC and speciation
High-precision GC-FID systems for monitoring air quality and industrial emissions.
Standard-Compliant GC-FID Solutions for Continuous VOC Monitoring
To meet the most stringent environmental and regulatory requirements, Chemlys integrates the P5100 series of online analyzers. Designed for industry and ambient air monitoring, these robust systems ensure ultra-precise quantification of total VOCs, NMHCs (non-methane hydrocarbons), as well as complete speciation of hydrocarbons from C2 to C12.
A robust GC for your online VOC analysis
Integrated in 19-inch rack format, P5100 analyzers meet the requirements of industrial environments and air monitoring networks.
Faced with tightening environmental standards (European Industrial Emissions Directive - IED, compliance with Occupational Exposure Limits - OELs) and increasing demands for data traceability, the reliability of continuous measurement is a major challenge.
P5100 analyzers meet the strict constraints of industrial environments and air quality monitoring networks. Designed to fit into a rigorous metrological approach, they easily fit into your analysis bays. They ensure maximum availability and incorporate extensive calibration automation, ensuring accuracy, repeatability of measurements and continuous validation of your data in accordance with regulatory requirements.
Do you have a VOC or NMHC analyzer project? Commitment Chemlys
At Chemlys, we know that the analyser alone is not enough: sampling and service make all the difference. By choosing our solutions, you benefit from a complete accompaniment from A to Z:
- Consulting & Needs Assessment: In-depth analysis of your application, definition of the optimal GC configuration, and selection of the most suitable accessories.
- Provision of sampling aids: Provision of heated transfer lines, filtration systems, sampling pumps, and valves tailored to your specific industrial process.
- Commissioning & Validation: On-site installation, method setting, and device validation according to your repository.
- Calibration & Consumables: Supply of permeation tubes, certified calibration gases, and chromatography consumables to guarantee the accuracy and metrological traceability of your measurements.
- Maintenance & Repair Services: Preventive and corrective maintenance contracts (annual or multi-year) delivered by our dedicated technical experts across France and Europe, ensuring maximum uptime for your equipment.
The range of air quality analyzers is available in three major configurations:
-
P5100 NMHC: Continuous measurement of Methane (CH4), Total VOCs (TVOC), and Non-Methane Hydrocarbons (NMHC) using the subtractive method (Dual FID).
-
P5100 C2-C6: Speciation of light hydrocarbons (from ethane to benzene, including 1,3-butadiene) using a thermal preconcentration module.
-
P5100 C2-C12+: "All-in-one" solution for the complete VOC spectrum, including trace monitoring of BTEX (Benzene, Toluene, Ethylbenzene, Xylenes) (ppb/ppt).
Operating Principle:
The operation of the P5100 series is based on Gas Chromatography coupled with a Flame Ionization Detector (GC-FID).
-
Sampling and preconcentration: The use of absorbent traps with rapid thermal desorption for models C2-C6 and C2-C12, allowing detection limits to be reached in the order of the ppt.
-
Industrial Format: Designed as a standard 19” industrial rack.
-
Regulation: Electronic Pressure Control (EPC) and Mass Flow Controllers (MFC) ensure impeccable retention time repeatability.
-
Interface and communication: Front-facing touch screen, integrated intuitive monitoring software, industrial communication protocols (TCP/RTU Modbus, 4-20mA analog outputs, alarm relays).
-
Autonomy: Automatic management of column analysis, calibration and self-cleaning sequences.
Normative Compliance and Performance:
Our solutions are designed to meet the strictest international and European standards for environmental monitoring.

Our Custom Approach to Successful Online Analysis
Engineering & Needs Assessment
Beyond the device, your reality ground.
Each industrial process is unique. That is why we do not start from a catalogue, but from your project. Our experts carefully study your context, regulatory issues and the physical constraints of your environment (complex gas matrix, extreme conditions).
Our goal: to define a perfectly sized sampling and analysis architecture for your application.
A True Commitment to Results
The guarantee of a solution that works for you.
The theoretical specifications of a manufacturer are not sufficient to guarantee the success of an industrial application.
