I am positive in hoping some of you had used in the past couple years the Geller microanalytical system (dQuant and dPict) and could help me. We are facing a major computer issue, and we believe one of our computer board is nearly dead (motherboard and/or some of the communication boards installed by Geller to communicate with our JEOL). The computer is freezing regularly every couple minutes or, if we are lucky, every couple hours "only". We have already changed the power supply, changed the memory (RAM), changed the hard drive, and freshly re-install all the software / drivers... No change. We are now considering changing the computer, and in the mean time getting the new version of dQuant / dPict software from Geller. My questions are... a) Did any of you recently upgrade / install the version 7 of dQuant? We are at version 3.41 and we wonder if this is really worse spending ca. $20K for this upgrade: $10K for new boards, $2K for a new computer (including installation), $5K for the software, and ca. $2K for a new electrometer... b) Does any of you know how we can (and IF we can) do peak overlap correction within the Geller software? If so, do we need the newest software version for this? c) Does anyone had tried to upgrade to J. Donovan system (Probe for EPMA)? To work with the JEOL-8600, we need either a TN-5600 PAC system (cheap upgrade) or a hardware upgrade from Advance Microbeam. Some colleague already recommended me the Advance Microbeam upgrade, but this one is pretty expensive (and we are already thinking about applying for an MRI for a new probe). Any thought on that?
