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.

Abstract: Systems and methods are described for transferring gas from an ablation cell to an inductively coupled plasma analysis system via a gas exchange membrane transfer line to exchange gas introduced to the ablation cell with a sweep gas. A system embodiment includes, but is not limited to, a laser ablation cell configured to generate a sample transfer stream through laser ablation of a sample and introduction of a carrier gas to flow the ablated sample from the laser ablation cell; an inductively-coupled plasma analysis device configured to measure one or more analytes in the sample transfer stream; and a gas exchange membrane transfer line fluidically coupled between the laser ablation cell and the inductively-coupled plasma analysis device, the gas exchange membrane transfer line configured to replace gas in the sample transfer stream with sweep gas via gas exchange across a membrane of the gas exchange membrane transfer line.
