Abstract
A system and method for reliably testing for toxic substances is described. Based on spectrographic means, the system embodies one or more types of spectrometers, designed for the detection of toxic elements such as lead, and alternatively designed for the detection of toxic compounds such as asbestos. By restricting the broad functionality common to a typical spectrometer, dramatic cost reductions can be made permitting the device to be cost-effectively manufactured and made available to the typical consumer. The device is can be portable and incorporates safety systems to inhibit improper use.

1-67. (canceled)
A toxin detector comprising:
- a spectroscopic system for analyzing a sample, the spectroscopic system comprising:
- one or more collectors for collecting physical phenomena from one or more emission events associated with the sample;
- one or more filters for filtering the physical phenomena from the one or more collectors by one or more of isolating, reducing, amplifying, or sequencing the physical phenomena into a filtered spectra output;
- one or more detectors for receiving the filtered spectra output and producing one or more output measurement values;
- one or more transporters for transporting the filtered spectra output from the one or more filters to the one or more detectors;
- a determination system for processing the one or more output measurement values of the spectroscopic system, the determination system comprising a processor configured to perform one or more of:
- evaluating the presence or absence of a toxin against a known library of emission measurements;
- evaluating the prevalence of a toxin against a known library of emission measurements;
- collecting representations of measurement outputs value;
- and
- assigning a categorical classification to the one or more toxins based on a Partial Least-Squares Discriminate-Function Analysis (PLDA) statistical analysis of the output measurement value.
A device for determining the presence of one or more toxins, the device comprising:
- a spectroscopy system comprising:
- a light source selected from at least one of:
- Laser Induced Breakdown Spectroscopy (LIBS), Sliding Spark spectroscopy (SSS), Raman spectroscopy, Laser Ablation Emission Spectroscopy(LAES), X-Ray Fluorescence spectroscopy (XRF), and reflectance spectroscopy;
- an electromagnetic measurement device;
- one or more filtering elements positioned between the spectroscopy system and the electromagnetic measurement device and configured to pass one or more specific persistent emission lines associated with the one or more toxins to the electromagnetic measurement device;
- and
- a processor configured to receive data from the electromagnetic measurement device and to determine the presence of the one or more toxins.
