Abstract
Humidification systems and methods to introduce water vapor to a laser-ablated sample prior to introduction to an ICP torch are described. A system embodiment includes, but is not limited to, a water vapor generator configured to control production of a water vapor stream and to transfer the water vapor stream to at least one of a sample chamber of a laser ablation device or a mixing chamber in fluid communication with the laser ablation device, wherein the mixing chamber is configured to receive a laser-ablated sample from the laser ablation device and direct the laser-ablated sample to an inductively coupled plasma torch.
