AMI-300 HP

AMI-300HP is a fully automated high-pressure chemical adsorption analyzer developed by ALTAMIRA based on its flagship model AMI-300. A dynamic high-pressure programmed heating experiment that can be performed at pressures up to 100 bar. It can integrate liquid-phase feeding function and be used as a desktop microreactor, providing fully automated microreactor characterization function for catalyst industry users.

PRODUCT FUNCTION

7 standard functions

Pulse chemical adsorption, TPR / TPO，TPD，TPRx， Steam adsorption, pulse calibration, and dynamic BET. Can program 99 processes into one experiment.

Sample loop

There are 13 models to choose from, providing a convenient way to meet different quantity requirements.

Real time measurement of sample temperature

A movable temperature measuring thermocouple is placed at the top of the sample bed.

Furnace

The temperature range is -130 ℃ to 1200 ℃, and it can be heated linearly at a rate of 1-50 ℃/min.

The sample is easy to load

Mobile shell furnace makes it easy to remove and load sample tubes.

Overall pipeline insulation

All valves and pipelines are placed in a heatable and insulated box to prevent condensation.

External mass spectrometer

Real time integration of MS data and AMI-300 data is achieved through Direct Data Exchange (DDE).

Whole structural material

The quality seals and materials are customized and designed according to your needs.

4 high-precision Mass Flow Controllers (MFCs)

Implement automatic gas switching and precise control in the experimental process to ensure stable TCD baseline during the experiment.

Multiple types of sample tubes

Quartz U-shaped tubes that can accommodate samples of various sizes to accommodate the volume and size of different catalyst samples. The sample form can be powder, particle, strip or honeycomb.

Cold trap

A cold trap filled with desiccant can be installed downstream of the sample tube to remove condensates before flowing through TCD.

Multiple material reactors

Quartz anti reactor (atmospheric pressure)
316SS reactor (high pressure)
Inconel, Hastelloy or other high temperature resistant materials (customizable)

TCD detector

A high-precision 4-fire TCD detector with high linearity, accuracy, sensitivity, and stability. There are different filament materials to choose from.

Auxiliary detector

Can accept any auxiliary detector that provides analog voltage output, such as flame ionization detector (FID).

Safety protection

Independent furnace over temperature protector, gas safety valve, check valve, circuit breaker, and TCD anti dry burning system.

AMI-300HP Control Features

AMI-300HP is a fully automatic atmospheric/high-pressure system. There are the following functional features:

TECHNICAL INDEX

Software Control

The AMI-300 HP model is a fully automatic instrument controlled by a computer, with reliable data and easy operation.
It is not necessary to have an operator on duty all the time during the experiment. Can be installed on Windows based computers, can be connected to the internet, and in addition to controlling instruments, the computer can also manage other laboratory tasks.
The "Overview" interface displays the device status at a glance, providing information such as the position of all valves, gas type, temperature, and detector signals for each port. The change in line color can indicate the current flow path.
Fully automatic control of valve switching, reaction temperature, heating rate, gas flow rate, gas mixing parameters, and detector parameters.

The powerful software control function of AMI series

Experimental program setting interface

Users can flexibly select or edit TPD, TPO ,TPR , TPRS, Pulse chemical adsorption, quantitative ring calibration experiments, etc. can be set up with up to 99 programs to achieve full automation of adsorption, desorption, and chemical reactions. The complete experimental setup can be completed within a few minutes and saved for future use or modification.

Instrument safety protection program setting interface

The software has an alarm program that can implement various security protection mechanism settings. In manual mode, simply click the mouse on the icon to switch any valve. You can input gas flow rate and set temperature values from the page.

Interface for collecting mass spectrometry data

Can be connected to mass spectrometry (MS) or gas detectors, supports multiple external detectors, provides series and parallel connection methods, can embed mass spectrometry (MS) data acquisition into AMI software, and achieve the same file export of TCD&MS; data
