AMI
AMI 300
Chemisorption Analyser
- Fully automated chemisorption analysis for comprehensive catalyst characterisation.
- Customisable system with advanced software and temperature control.
- High precision and safety, featuring sensitive detectors and durable materials.
Key Features
Electronic Flow Controllers
The system is equipped with high-quality linear mass flow controllers for precise and stable gas flow control, ensuring accuracy in chemisorption applications. The standard flow range is 2–100 sccm, with additional ranges available upon request for customized setups. These controllers offer excellent linearity and repeatability, providing reliable and consistent gas dosing throughout all programmed procedures.
High-Temperature Furnace
Features a versatile furnace system capable of reaching temperatures up to 1100°C. With optional sub-ambient cooling, the system can achieve temperatures as low as -130°C, making it suitable for a wide range of thermal and catalytic applications. The furnace supports linear temperature ramping from 0.1°C per minute to 50°C per minute, allowing precise control over heating profiles for reduction, oxidation, desorption, or reaction studies.
Sensitive Thermal Conductivity Detector
A highly reliable 4-filament thermal conductivity detector (TCD) is used to accurately quantify gas uptake. It offers excellent linearity, accuracy, sensitivity, and long-term stability. Multiple filament configurations are available to suit different analytical needs and gas types.
Various Sample Holders
The AMI-300 is the only system on the market that enables direct analysis of monolith samples (with an optional monolith holder), in addition to supporting a variety of quartz U-tubes—including standard, bubble, and custom designs. It accommodates a wide range of sample forms and loadings, such as powders, pellets, extrudates, and honeycomb cores, making it exceptionally versatile for real-world catalyst testing and development.
Precision Gas Control with Independent MFCs and Blending
The AMI-300 features three mass flow controllers (MFCs) for independent control of carrier, treatment, and auxiliary gases, with an optional fourth MFC for advanced setups. It supports internal gas blending for precise atmosphere control, and an auxiliary gas inlet can mix with carrier or treatment gases as needed. Rear-panel gas ports simplify access, with four each for treatment and carrier gases, two auxiliary/blending ports, and up to 12 total ports, ensuring versatility for chemisorption applications.
Interchangeable Valve Loops
A set of 13 optional injection loop modes provides an easy and flexible way to meet the adsorption volume requirements of different sample types. Available upgrades include microliter loops in 5, 10, 15, 20, 23, 50, 100, 250, and 500 μL sizes, as well as milliliter loops in 1, 2, 5, and 10 mL volumes. These options ensure precise dosing for both low and high surface area materials across a wide range of applications.
Low Internal Volume and Heated Lines
Low volume valves and 1/16″ lines are used to reduce void volume and minimize peak spreading. All lines, valves, and parts of the liquid Vaporizer are heated to prevent condensation.
Materials for Maximum Durability
Seals and materials are designed to meet your specifications, with options that include premium elastomers (Kalrez), passivated 316 stainless steel, Monel or Hastelloy valves, and Inconel reactors.
Rapid Air cooling
The system rapidly cools the furnace, enabling quick sample turnaround and increased throughput for busy laboratories.
Precise Sample Temperature Measurement
Sample temperature can be measured or controlled by either the furnace thermocouple or a movable thermocouple positioned at the top of the sample bed, offering flexibility and precision for various experimental needs.
Cold Trap
A cold trap downstream of the sample holder protects the TCD from moisture and condensable vapors. It features a Dewar flask for slurry-based condensation or a desiccant option for low-volatility experiments, ensuring a stable baseline, extended detector life, and reliable TPR, TPO, and dynamic measurements.
Software
The AMI-300 features an intuitive and clearly structured interface, with a well-organized graphical display and logical operational flow. This design dramatically reduces the learning curve, making the system easy to navigate for both new and experienced users.
Operation is simplified and streamlined, minimizing the risk of user error while ensuring smooth, consistent experimentation. The software provides comprehensive process monitoring, with real time status indicators and fully traceable data logging for enhanced reliability and experimental control.
In addition to control and monitoring, the AMI-300 offers advanced data processing capabilities, including peak fitting, peak separation, integration, differentiation, and overlay analysis. These powerful tools enable precise characterization of catalyst surface properties, distribution of acidic and basic sites, activation energy, reaction kinetics, and more—delivering deep insight into complex catalytic behaviors.

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.

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.
