Chemisorption AMI-300HP ● Automatic chemisorption analyzer with pressure capability up to 100 bar. ● Precise gas control via 3 MFCs (optional 4) and 4 standard gas inlets (expandable to 10 or 12). ● Broad temperature range: ambient to1200°C (optional-130°C low-temp configuration).

The AMI-300HP is an automated high-pressure chemisorption and catalyst characterization system, engineered for advanced research under industrially relevant conditions. It performs dynamic temperature-programmed experiments at pressures up to 100 bar, enabling detailed studies of catalyst behavior under true process environments.

Designed for maximum flexibility, the AMI-300HP can also function as a high-pressure gas-phase reactor, providing a dual-purpose solution for laboratories requiring both chemisorption analysis and reaction testing in a single, integrated platform. This capability enhances its utility for catalyst performance evaluation, process development, and kinetic modeling.

Key Features

High-Pressure Operation

Clamshell furnace capable of reaching 1200°C (max. temperature dependent on reactor type), with precise ramp rates from 0.1°C to 50°C per minute.

Stable Gas Flow Control

High-precision mass flow controllers (MFCs) ensure stable flow control and consistent TCD baselines, even during temperature-programmed experiments.

Condensation Prevention

Heat-traced stainless steel flow path eliminates condensation risks, preserving gas- phase integrity.

High-Sensitivity Detection

A highly linear Thermal Conductivity Detector (TCD) provides exceptional accuracy and sensitivity across a broad range of conditions.

Software Alarm Matrix

A dynamic alarm matrix provides live feedback and alert notifications for all monitored parameters. Logging alarm events ensure traceability and compliance with lab safety protocols.

Advanced Safety and Protection

· Independent Over-Temperature Protectors on the furnace prevent thermal runaway.
• Resealable Pressure Relief Valves automatically vent excess pressure and reseal without damage.
• Check Valves prevent backflow and protect against gas cross-contamination.
• Fail-Safe Design ensures the system defaults to a safe state during critical failures or power loss.
• Positive Shut-off valves to ensure complete isolation of gas lines when not in use, enhancing safety and preventing cross-contamination.

Flexible Customization Options:

• Custom reactors in a variety of types and sizes,
• High-pressure MFCs with customizable flow ranges to suit specific gas delivery requirements.
• Vaporized liquid delivery systems for injecting volatile or condensable reactants.
• Sub-ambient operation down to -130°

Software

The AMI-300HP is fully automated to ensure ease of use, repeatability, and reliable operation. Its integrated software precisely controls and regulates valve positions, temperatures, gas flow rates, and detector parameters, providing seamless management of complex experimental setups.

Data acquisition is performed at a user-selectable rate, allowing for optimized resolution and performance. A front-panel status screen offers a real-time overview of the system, displaying valve positions, connected gas types, active temperatures, and detector signals—all at a glance.

The built-in data handling package enables users to:

Display and integrate signal peaks
Calculate chemisorptive parameters
Overlay and compare datasets

Users can link up to 99 individual procedures in a single, continuous run, enabling fully automated, comprehensive catalyst characterization. Additionally, routine experiments can be designed and stored for quick and easy retrieval.

Outstanding service

I have been using Meritics for a number of years and they always provide outstanding service and support.
They have a rapid response turnarounds and are very knowledgeable of the techniques and products they provide.

LeanneB-375

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.

Excellent service from an excellent company. Would recommend them to anyone.

BarryH-480

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

TomA-446

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….

JamesG-2483

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.

RajG-62

Fully committed to customer service

Service second to none, both units serviced and all questions answers by engineer while on site.

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.

VeerleB

Very helpful and prompt

I emailed for some technical help and also to get some spares and both the engineer (David) and purchasing (Sophie) were very prompt to respond and helpful. We do have a service contract but I appreciated being able to email the engineer directly.
