Product Overview

The AMI-300 flagship model is the first generation fully automatic chemical adsorption analysis instrument provided by AMI Instrument Company. This instrument is a fully automatic catalytic characterization instrument designed based on the unmanned concept, with high reliability independent control software and complete data processing software. It was first developed by catalyst researchers and serves catalyst researchers as a chemical adsorption instrument. It, along with its predecessors AMI-1, AMI-100, and AMI-200, is the industry's first chemical adsorption instrument that provides fully automatic analysis and testing. This instrument can provide necessary kinetic parameters for characterizing catalysts.

Function

Product Features

7 standard functions

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

10 air intakes

There are 4 channels for processing gas and carrier gas, and the remaining 2 ports can be used for mixed gas or auxiliary gas. Additional ports can be added.

Quantitative ring

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

High temperature furnace

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

Gas mixing ability

AMI-300 has gas mixing function and can replace expensive gas mixers, such as conducting TPR or TPO experiments that require multi-component gases.

3 independent MFCs

In addition to controlling the carrier gas and process gas, there is also an MFC that independently controls the auxiliary gas (which can be mixed with the carrier gas or process gas).

High precision Mass Flow Controller (MFC)

The flow rate is 5-50ml/min (under standard conditions). Other ranges can be selected according to requirements.

Real time measurement of sample temperature

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

Liquid evaporator

Equipped with a heatable spray type saturator, it can easily introduce volatile liquids.

Air cooling components

Automatic control, quickly cooling the furnace through air blowing to shorten the experimental time.

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.

Feature

Product Features

Insulation zero station

Ensure that the gas does not come into contact with the sample during the calibration pulse process to improve accuracy.

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).

The system has a small dead volume

Use low volume valves and 1/16 pipelines to reduce dead volume and minimize peak diffusion to a certain extent.

safeguard

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

The sample is easy to load

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

Cold trap

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

Quantitative injection port

Provides a quantitative needle injection port for precise calibration of the quantitative ring volume.

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).

Structural material

The seals and materials are custom designed according to your needs.
