Product Overview

Introduction

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.

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.
