Based on our successful AMI-300 instrument, the AMI-300Lite provides rapid catalyst characterization in a compact, affordable package. The AMI-300Lite was designed specifically for the price-conscious customers with applications that are more routine or less demanding. As always, full automation and powerful data-handling software assure data accuracy and improve laboratory efficiency.

The AMI-300Lite

The AMI-300Lite represents a new affordable standard in automated chemisorption analysis. Developed by and for catalyst researchers, it and its predecessors, the AMI-1/100/200, were first in the industry to offer a fully automated system capable of performing all the major dynamic techniques required for fully characterizing a catalyst. The AMI-300Lite utilizes proven technology for performin g the following procedures:

Up to 99 procedures can be linked together back-to-back to provide a complete character ization experiment. Routine experiments can be designed and stored for easy retrieval.

 

Hardware and Operation

The AMI-300Lite is a fully automated, atmospheric pressure system. Through software control, it can switch gas streams, control gas flow rates, control temperature and temperature ramps, and collect desorption data in order to quantify the adsorption and desorption of gas molecules for a catalyst surface. To improve the quality of data, the AMI-300Lite utilizes a high-precision electronic mass flow controller for both the carrier and treatment gases. This ensures constant treatment flow and a stable baseline with changing temperatures. Dead volume is minimize by using 1/16 inch plumbing in order to reduce peak spreading. The furnace can heat the sample to 1000°C and is capable of linear temperature ramps from 1°C/minute to 30°C/minute.

The AMI-300Lite is fitted with a highly linear thermal conductivity detector (TCD). A choice of filament types is offered to maximize the sensitivity for your particular analysis.

 

Computer Control and Data Acquisition

The AMI-300Lite is fully-automated for ease of use and reliability. The control portion of the software controls and regulates all valve positions, temperatures, flow rates, and detector parameters. Data acquisition occurs at a selected rate for optimum performance. An "Overview” screen shows the status of the unit at a glance. This screen provides information on the position of all valves, type of gas connected to each port, temperatures, and detector signal.
