Dear all, Our electron microscopy lab at the University of Nevada Las Vegas (EMiL lab: https://emil.sites.unlv.edu/ <https://emil.sites.unlv.edu/>) is looking to purchase a new carbon coater to conduct geological electron microscopic analyses (using SEM, FE-SEM, and EPMA, for EDS, EBSD, etc analyses). We would like to know your opinions regarding reliable carbon coaters (brands, rods or ropes, etc.) that you have used in your labs. Thank you very much, Best regards Arya ********************************* Arya Udry, Ph.D. Associate Professor Graduate Coordinator Department of Geoscience University of Nevada, Las Vegas 4505 S. Maryland Parkway Las Vegas, NV 89154-4010 (702) 895-1239 arya.udry@unlv.edu https://aryaudry.com/ (she/her)

Arya, We have a Leica EM ACE600 <https://www.leica-microsystems.com/c/am/lsr-n/sputter-coater-ppc/?nlc=20231229-SFDC-019285&utm_source=google&utm_medium=cpc&utm_campaign=23-AM-LSR-L3-NAPF-GOOG-PP-Sputter-Coater-Search&utm_content=text_ad&utm_term=leica%20sputter%20coater&gad_source=1&gclid=CjwKCAjw9p24BhB_EiwA8ID5BopnYZO3buyGWkFN2DOCpajGpnIRbuOuAvwAJJd0q1Vr32eTHw9ljRoCCnIQAvD_BwE> configured for carbon thread sputter coating and glow discharge. We have been very pleased with the ability to deposit very fine and consistent carbon coats. You can set the desired coating thickness, and the result delivered is very accurate. The coater is easy to use, and you can program different recipes for different sample requirements -- making it easy to use for users of any level. The coater can handle three geological thin sections or about 25 standard sem stubs in a single session. We coat about 1-2x a month on average. The carbon thread is expensive but in the 17 months that the coater has been installed, we have only used ~1/2 a spool of carbon thread. We have heard from multiple sources not to try and use third-party carbon thread, as the resulting coat will be worse and you will use more thread per session. All that said... It is an expensive option. But we have found the expense worthwhile. Cheers, Hanna Hanna L.

Dear Arya, We have the same coater as Hanna, and I completely agree with her assessment. Easy to use, and relatively quick to pump down. We have a N2 tank connected to help with faster venting. Our unit sits on a standard lab bench.

Dear Hanna and Cam, Thanks for your recommendation. I am managing the Electron Microprobe at U Hawaii Manoa. We are planning to purchase this product (Leica EM ACE600) as well. It's great to hear good feedback on the consistent carbon coating performance. We were wondering whether you have tried to coat other metal sources as advertised in their product, such as Al, Ir, Au. I am curious whether there is a contamination concern when switching the metal sources and whether the process of switching and different metals coating is an easy job. Any feedback would be appreciated.

Hi Peng, No, we do not run other metal coatings at Amherst College. We have a separate gold sputter coater on campus, and carbon is adequate for samples going into our SEM or to the UMass Amherst microprobe. I have heard from our service tech that running other metals makes the inside of the chamber harder to keep clean. I clean the inside of our Leica EM ACE600 every 3-4 months to remove excess carbon. This is an important step as it helps the machine achieve and maintain vacuum, as well as reduce the risk of shorting the power supply. Cheers, Hanna Hanna L.
