Please let me check with the IT people. I asked them once when Zoom was being set up during "Covid;" at that time, there was no limit-it was a "benefit" for working at the Smithsonian! But times change and I should check; they should be available in an hour or two.

That sounds like a very interesting event. Is the invitation intended for the list members here only, or would it be okay to spread the word further to interested people? If so, I would like to forward the invitation via my contact list at textileforum.org (where I've recently started to send out information about conferences and lectures), and the EuroWeb "Europe Through Textiles" network. I think it would be very much of interest to some members of these groups.

Asher Newsome, Physical Scientist, MCI. He has been able to analyze dyes and pigments with DART-MS using this method. He did a short presentation of this method at DHA41 last year. Mary Thursday, August 10, 2023, 10:30am Eastern Daylight Savings Time (USA) Zoom Meeting Link: https://smithsonian.zoom.us/j/87327339225?pwd=ZmcyNktBb3dQcWIzWmJDdXk1YU9Idz09 Meeting ID: 873 2733 9225 Passcode: 768672 Material analysis is needed to support all manner of research at the Smithsonian. However, it is often important to the museum and other interested parties that rare, precious, or culturally sensitive objects remain undamaged. Mass spectrometry in its various forms presents a powerful tool, but it is inescapably destructive at some level. As the sensitivity of modern instrumentation grows, the sample mass that must be collected and ionized shrinks, perhaps to the point where it becomes debatable whether the amount removed constitutes "damage". Ambient mass spectrometry methods offer particular opportunities for sensitive object analysis because they can theoretically be performed without cutting material from a whole or preparing the surface. I will present several recent projects that pertain to different forms of minimally invasive, ambient sampling from materials such as wood, parchment, textiles, and synthetics, among others. I will also show recently developed instrumentation methods that accommodate intact objects too large to fit immediately adjacent to the mass spectrometer.
