Abstract: Methods and systems for predicting signal quality. One analytical instrument support system receives preliminary sample data collected from a short scan of a sample. The analytical instrument support system determines a bright-max intensity level based on preliminary sample data. The analytical instrument support system determines a performance class based on, at least, the bright-max intensity level. The analytical instrument support system determines an intensity-to-time model, the intensity-to-time model includes a plurality of intensity to levels and a plurality of exposure times based on, at least, one or more deviations from an intensity linear model, the one or more deviations associated with the determined performance class. The analytical instrument support apparatus determines a first maximum intensity level based on, at least, a first corresponding exposure time and the intensity-to-time model, or a first parameter exposure time based on, at least, a first corresponding intensity level and the intensity-to-time model.

Abstract: A computer-implemented method and system are provided. An analytical instrument support system receives a first spectra dataset associated with scans of one or more first samples, the one or more first samples including a target analyte having one or more known levels of a parameter. The analytical instrument support system receives a second spectra dataset associated with scans of one or more second samples. The analytical instrument support system determines one or more spectra arrays by combining (i) the first spectra dataset and (ii) the second spectra dataset. The analytical instrument support system determines a chemometric model for one or more levels of the parameter of the target analyte based on, at least, the one or more spectra arrays and the one or more known levels of the parameter.

Abstract: Disclosed herein are scientific instrument support systems, as well as related methods, computing devices, and computer-readable media. For example, in some embodiments, a scientific instrument support system may be an autochemometric system that automatically trains machine-learning models with spectroscopy data. The trained models can then be used to identify and/or authenticate the presence of particular substances in a sample under test.

Abstract: In the operation of analytical devices, and particularly laser induced breakdown spectroscopy (LIBS) devices, a number of advantages may be obtained by the use of complementary safety mechanisms, such as those that govern the operation or firing of a laser. Such complementary safety mechanisms, compared to the individual safety mechanisms acting alone, prevent operation of the laser under a greater number of unsafe circumstances (even if one or more detected conditions are safe, based on not activating the associated safety mechanism) and permits operation under a greater number of safe circumstances (even if one or more detected conditions are unsafe, based on activating the associated safety mechanism).
