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.

Description
- The AMI-Surface DX Series offers a fully automated solution for BET surface area analysis using dynamic flow adsorption. Designed for high-throughput labs, it features four parallel analysis stations, enabling simultaneous testing and significantly reducing turnaround times.
- Operating without a vacuum system, the AMI-Surface DX uses a dynamic flow (non-static) method that supports both single-point and multi-point BET analysis. This makes it ideal for quality control, R&D, and production environments, especially for low surface area materials. With reference comparison methods, adsorption peaks are detected rapidly and accurately—delivering precise results with exceptional speed.

FEATURES
- Patent of Invention
- Accurate adsorption measurements based on sharp peak detection eliminate errors caused by incomplete desorption. Ideal for low surface area samples such as ternary materials and battery electrode materials. (Patent No. 20140320453.2)
- Automatic Nitrogen Partial Pressure Control
- Surface DX 400 is equipped with high-precision mass flow controllers to automatically regulate nitrogen partial pressure during BET surface area measurements. This ensures stable and accurate gas flow across the sample surface, delivering consistent and reliable adsorption results with minimal manual intervention.
- Four Parallel Operating Analysis Stations
- Run up to four samples at once with independently controlled stations. Achieve unmatched throughput with consistent test conditions and result repeatability better than ±1.0%.
- Anti-Elutriation Technology
- A built-in anti-contamination unit prevents sample particles from entering the instrument's internal gas line, ensuring operational reliability and long-term cleanliness.
- Optional Sample Preparation Unit
- External sample preparation device with four-degas stations can remove adsorbed contaminants from surface and pores of samples with heating in flowing gas/vacuum. Temperature can be set and controlled from ambient to 400 ºC.
- Low Form Dewar flask
- Long lasting, high volume (1 L) Dewar flasks assure a constant thermal profile along the length of sample tubes during experiment.
- Fast, Sensitive Testing
- Adsorption peak looks sharp, no trailing phenomenon, the change of nitrogen concentration caused by each sample adsorption is not diluted at all; the sensitivity of the sample test is greatly improved. The test efficiency is greatly improved under the condition of sufficient adsorption and the comparative test of four samples in one time only needs about 15 minutes.
SOFTWARE
- The AMI-Surface DX software provides intuitive operation with real-time visualization of nitrogen and helium flow. During analysis, users can monitor adsorption activity dynamically, offering a clear understanding of test progress and conditions. Ideal for both novice and advanced users, the interface ensures reliable, traceable operation.
