The Micromeritics Autopore 9210 features computer controlled mercury intrusion from sub-ambient pressure to 60.000 psia (414MPa).

The AutoPore III mercury porosimeter measures a wider range of pore size distributions more quickly than other technologies and with greater accuracy. Pore size distributions ranging from 0.003 to 360 um in diameter can be determined. The high resolution pressure/intrusion system and A/D converter permit extraordinary resolution of pore size and volume data - better than 0.1 uL.

The AutoPore III also supports many analysis options for determining pore size distributions, total pore volume, total pore surface area, median pore diameter, and sample density. Equilibration options include choice of time-based or intrusion-rate equilibration of pressure/volume measurements, providing you with the most powerful data you can get.

To meet high throughput demands, the AutoPore III features three sample ports: two low pressure (0 - 50 psia) ports and one high pressure (ambient - 60,000 psia) ports. The sample penetrometers, which are installed on the ports during analysis, come in different sizes, i.e. sample measurement ranges. The ability to choose from a wide assortment of penetrometers is significant because the more closely the measurement range of the penetrometer matches the sample's shape and porosity, the more precise the final results.

To make sure each analysis collects all the information you need, the AutoPore III can execute a program for limiting maximum intrusion volume between data points. This means if the sample starts to take up a lot of mercury - at any time -then the AutoPore III will stop and collect additional data points automatically. Yet if it encounters a region where no intrusion is occurring, it will not waste time collecting a lot of data points. The result is a complete set of data obtained in the shortest amount of time possible.

Analysis data are presented in tables, plots, and calculated summaries. The formats can be edited, re-arranged, and customized to suit your output requirements. Plots of cumulative, incremental, and differential data allow quick evaluation of primary sample characteristics.
