AMI-400

Overview

Overview

The AMI-400 is a fully automated chemisorption analyser that can be used to perform dynamic temperature-programmed experiments to characterise catalytic surface activity. It can perform pretreatment of catalysts, followed by analysis such as temperature-programmed desorption (TPD), temperature-programmed oxidation (TPO), temperature-programmed reduction (TPR), and temperature-programmed reaction (TPRx). 

The AMI-400 can also perform automated pulsed chemisorption and single point (optionally multi-option) BET surface area measurement.

Function

Catalyst performance is only as well understood as the data behind it. With the AMI-400, researchers can obtain:

  • Metal dispersion and surface activity — understand how effectively active metals are distributed across a catalyst.

  • Temperature of catalytic activation — pinpoint the exact temperature at which metals become catalytically active.

  • Strength of active sites and adsorption energy — measure how strongly reactants interact with the catalyst surface.

  • Gas uptake and desorption kinetics — quantify how much gas is adsorbed or released, and at what activation energies.

  • BET surface area — determine single-point or multi-point surface area measurements with ease.

  • Breakthrough curve analysis – quantify the working capacity of adsorbent samples under process-relevant conditions

  • Cyclic stability – determine the number of adsorption/desorption cycles that the sample can undergo

By running TPD, TPO, TPR, TPRx and pulsed calibration in fully automated sequences, the AMI-400 turns complex multi-step analyses into reliable, repeatable datasets—ensuring confidence in every result.

Features

Many analysers can run basic chemisorption tests, but few are built with the depth of engineering that makes the AMI-400 a trusted choice worldwide:

Full automation & programmable sequences

— chain unlimited treatments and analyses for true “walk-away” operation.

Sub-ambient to ultra-high temperature control (-130 to 1,200°C)

— study catalysts behaviour from cryogenic to extremely high temperatures.

Heat-traced stainless steel flow paths

— eliminate condensation risks, ensuring accurate detection and data integrity.

Built-in gas blending

— create custom gas mixtures on demand, without having to buy pre-mixed gas cylinders.

— generate custom mixtures at any required concentration, giving the freedom to design experiments around your research goals rather than the availability of pre-mixed cylinders.

Auxiliary detector integration

— connect seamlessly with MS, FID, or other detectors; merge data in real-time for richer insights.

User friendly software

— colourful intuitive software interface that displays all operating parameters for easy monitoring.

These features aren’t just technical specifications—they translate to lower operating costs, fewer errors, and deeper insights, making your catalyst research more productive.

Applications

The AMI-400 is trusted by leading catalyst manufacturers, petrochemical companies and energy corporations who rely on precise surface characterisation to optimise catalyst design and scale up new formulations. It is used to study heterogeneous catalysis for petrochemical processing, sustainable fuels and emissions control.
