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.

Humidification of laser ablated sample for analysis

Systems and methods for measuring analytes (e.g., potassium) under hot plasma conditions of ICP analysis systems (e.g., ICP-MS, ICP-AES, etc.) are described, where a membrane desolvation unit and nitrogen flow gas are included to reduce Argon interferences. A system embodiment includes a heated spray chamber configured to receive a liquid sample and a sample gas to aerosolize the liquid sample; a first condenser coupled to the heated spray chamber; a second condenser coupled to the first condenser; a heated membrane coupled to the second condenser; and a gas introduction component coupled to the heated membrane to receive a flow of gas and to combine the flow of gas with a dried sample aerosol leaving the heated membrane, wherein the flow of gas is introduced at a rate of approximately 2.67 percent to approximately 20 percent of a flow rate of the sample gas.
