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 calibrating an analytical instrument analyzing a plurality of sample matrices in series. A system embodiment can include, but is not limited to, a sample analysis device configured to receive a plurality of samples from a plurality of remote sampling systems and to determine an intensity of one or more species of interest contained in each of the plurality of samples; and a controller configured to generate a primary calibration curve based on analysis of a first standard solution having a first sample matrix by the sample analysis device and generate at least one secondary calibration curve based on analysis of a second standard solution having a second sample matrix by the sample analysis device, the controller configured to associate the at least one secondary calibration curve with the primary calibration curve according to a matrix correction factor.

Abstract: A system embodiment includes, but is not limited to, a syringe pump operably coupled to a desolvation unit, the desolvation unit coupled to a sample analyzer configured to measure an intensity of one or more analytes in a sample solution provided through operation of the syringe pump; and a controller operably coupled to the syringe pump, the controller configured to receive the intensity of the one or more analytes measured by the sample analyzer, determine whether the intensity exceeds a threshold difference of an intensity of at least one standard measured by the sample analyzer, and adjust one or more control parameters of the syringe pump when the intensity of the one or more analytes exceeds the threshold difference to control a flow rate of the sample solution introduced to the sample analyzer.
