Yes, it is possible. Depending on the actual type, you can catch-log the raw data output of the machine from the Ethernet link to the machine. You need three things, the IP and port of the machine (can be found in the settings of the machine), and some tool to catch the data, something like Putty. The data stream starts with start of the actual measurement (analysis phase). The logging is easy task, just set up the Putty to listen on the machine's port and let it save the data, that's all.

The interval of the data output is usually 0.5 s and for all port at the same time (even not used), but again, probably depends on the actual model. The collected data are very detailed, time in milliseconds, pressures, dosed amount, adsorbed amount, volumes of manifold and sample cell are included among others. However, as this data are not part of the normal dataset, this procedure works only during the experiment. There is no back-logging according to my knowledge.

I am aware of the outdated answer, however, this information is usually not included in the manual. Hopefully it will help someone. Just be aware that the machine is constant volume experiment (pressure swing) and the method for kinetics calculation is little bit different.
