Dr Micha CampbellLooking for opinions on which 193 nm excimer laser ablation unit to get to couple with our Element 2 for high-res analysis trace and minor elements in carbonates (esp. speleothems). Trying to choose between RESOlution or ESL. If any geochemists/LAICPMS afficonados on here have OPINIONS on either of these (good or bad), please drop me a line!
