Key Features
-
Precise Thermal Conductivity Detector
The instrument is equipped with a high- precision, four-wire rhenium-tungsten TCD detector, featuring a constant temperature range from room temperature to 200°C. Additionally, filament types can be customized to match specific research needs, or the system can be integrated with auxiliary gas detectors such as mass spectrometers, FTIR, or FID, providing enhanced analytical versatility for a wide range of experimental applications.
All-in-One Constant Temperature
Precise Vapor Control – Ensures a stable and uniform temperature for consistent and reliable performance. Simplified Vapor Operation – Designed for easy and efficient vapor handling, optimizing experimental conditions and reproducibility.
Intelligent Gas Inlet Interface
A user-friendly port design eliminates the need for users to manually determine the type of gas used (carrier gas, process gas, or pulse gas); the software automatically selects the appropriate gas. The eight inlet ports meet daily testing needs, allowing multiple experiments without frequent gas interface changes, thus reducing user operations.
ibution dataIntegrated Constant Temperature Valve Box
The instrument’s process tubing is heated using a convection oven, maintaining a uniform temperature distribution with a maximum temperature of 130ºC. This design eliminates cold spots in the stainless-steel tubing, valves, and TCD detector, ensuring optimal performance and accurate measurements.
Precise Temperature Control
The system offers a temperature range from – 130°C (with optional configuration) to 1100°C, with linear heating ramps from 1 to 50°C/min.
Automatic Air-Cooling Module
Software – Controlled Automation – Enables precise and efficient cooling with no manual intervention required. Rapid Furnace Cooling – Utilizes air cooling technology to quickly lower furnace temperature, enhancing turnaround time and overall operational efficiency.
Accurate Flow Control System
High-precision MFCs regulate gas flow from 0-100sccm (+/-1% FS accuracy), ensuring stable, accurate measurements. A built-in mixing volume enables real-time gas blending for flexible experimental setups.
Cold Trap
A dedicated cold trap is installed downstream of the sample to effectively remove condensable substances before they reach the TCD detector, ensuring accurate measurements and extending the TCD’s operational lifetime.
Software
User-Friendly Software Interface
A clear graphical interface with logical flow simplifies navigation, minimizes errors, and ensures smooth experimentation with real- time monitoring and traceable data logging.
The system offers comprehensive data processing capabilities, including peak fitting, peak separation, integration, differentiation, and overlay analysis of signal peaks. This enables precise characterization of surface features of catalysts, distribution of acidic and basic-sites, activation energy, reaction kinetics, and more.
• Clear Control System: Real-time monitoring with a visual software system
• Simultaneously displays gas flow, temperature, and other information.
• Real-time display of temperature programming
• Real-time display of valve status

Good service, very helpful
We use Meritics for the PM service and installation of all our FlowCams . Megan has been coming to our site for a number of years. She is very efficient in her work, but most of all Megan is very helpful. We have had issues with one of instruments after the install and Megan did her utmost to try and solve it while on site, even though it wasn’t solved Megan has been in contact with the supplier of the instrument to try and solve this problem for us.

Good Service
David, our service engineer as usual was good at communicating and setting up the recent service appointment, he arrived on time, did the service promptly and informed me of any problems. Friendly and helpful

Superb and prompt service
I have used this company through the laboratory I work for frequently. We specialise in soil analysis, and Meritics were chosen as they have extensive knowledge of the instruments we use. We have several laser particle diffraction analysers with a service contract, and service is always very prompt and meticulous….

Good experience over two years
Meritics have covered the annual servicing of our Multisizer 4e instrument since we purchased it from them just over two years ago. The application scientist who performed the servicing was friendly, knowledgeable, and extremely helpful, happily answering a barrage of questions about how best to use and maintain the instrument. All my interactions with Meritics staff have been positive. I would happily recommend them.

Highly recommend Meritics for equipment purchases and aftercare services
After owning one of our instruments for over 8 Years which was purchased from Meritics, it suffered its first breakdown. Upon contacting Meritics, I was instantly put through to an engineer who was very helpful. Upon inspection of the manual, it was decided that it would be more cost effective to have a Meritics engineer visit. The Meritics staff were very communicative and kept me up to date.
Excellent Service
Lovely, friendly and extremely helpful. David and his team are always on call with advise and are very easy to work with and are always happy to help.

Professional, Customer-oriented, fast service
We had issues with one of the aperture tubes provided by Meritics on a Friday afternoon, while very pressed for a review deadline. Meritics handled our inquiries very fast and professionally and helped us out by shipping us their spare tube to use in the mean time free of charge, while we waited for our new tube to arrive. Communication was very pleasant.
