Video 1. High-speed video of the ICP during 266-nm laser ablation of a Y2O3 pellet using argon as the sample-transport gas.

Video 2. High-speed video of the ICP during nebulization of a Y solution standard with a 100 μL min-1 nebulizer. Argon was used as the sample-transport gas. Red clouds from large droplets occasionally cause flickering of the tip of the IRZ; few persist further downstream.

Video 3. High-speed video of the ICP during nebulization of a Y solution standard with a 20 μL min-1 nebulizer. Argon was used as the sample-transport gas. The IRZ is faint and the tip is very stable; few red droplet clouds are evident.

Video 4. High-speed video of the ICP during nebulization of a Y solution standard with a pumped 100 μL min-1 nebulizer and a cyclone spray chamber. Argon was used as the sample-transport gas. Droplet clouds and particle streaks are common in the red IRZ and blue NAZ.

Video 5. High-speed video of the ICP during 266-nm laser ablation of a Y2O3 pellet using helium as the sample transport gas and argon as make-up gas.

Video 6. High-speed video of the ICP during 266-nm laser ablation of a silicate glass doped with 12 wt% Y2O3. Argon was used as the sample-transport gas. The green emission in the NAZ is the result of imprecise color rendition by the 3-CCD camcorder; both the digital still camera and the naked eye correctly observed the normal blue emission color expected from excited Y+. Particle tracks are still evident but less frequent than when the Y2O3 pellet was ablated (videos 1 and 5).
