AMI-Surface DX

The AMI-surface DX represents a new affordable and fully automated high-throughput BET analyzer.  Perform single and multi-point dynamic BET experiments in a fraction of the time of static methods.  The AMI-surface DX is ideal for quality control. It can also be used in a wide range of industries from pharmaceuticals to oil and gas.   The AMI-surface DX can run four samples and combines the benefits of flow BET with full automation.

HARDWARE AND OPERATION

The AMI-surface DX is a fully automated dynamic BET instrument.  The AMI-surface DX utilizes two mass flow controllers (MFCs) to automatically adjust the partial pressures of nitrogen.  The 70mL/min and 30mL/min MFCs allow for precise blending which in turn results in highly accurate test results.  The AMI-surface DX uses the adsorption peak for analysis and in doing so eliminates the error caused by slow or incomplete desorption of nitrogen from samples. 

 Through software control, the AMI-surface DX can automatically:

• Adjust the partial pressure of nitrogen

• Raise and lower the dewar

• Zero the TCD

• Determine equilibrium conditions

• Save data to file for offline analysis

• Calibrate adsorption data
