Main features of the software
BPA-2S can operate as stand-alone instrument. It stores data on board for 180 measurements which can be downloaded to a PC. The software allows graphical display of several measurements for comparison. Graphics with various zoom functions supports the visual analysis of the data. Export as text file or directly into MS Excel. Unique instrument for very short adsorption times down to 0.1 milliseconds due to the application of the Fainerman measuring routine. Automatic and manual determination of the critical flow rate. Required small bubble volume and dead time possible due to specially designed capillaries.
