MEI-660: GUNSHOT RESIDUE IDENTIFICATION

The GSR analysis by SEM/EDS course emphasizes hands-on learning. Using two SEM instruments, students have the opportunity to study test samples provided by our staff, under the direction of McCrone scientists with over 15 years of combined SEM/EDS GSR analysis experience.

During the course, students learn through lecture, demonstration, and hands-on participation: theory of the SEM and EDS systems, how to setup and operate SEM and EDS instruments for GSR analysis. The students will be introduced to and participate in discussions of the ASTM E-1588 and SWGGSR guidelines for SEM/GSR analysis, interpretation of data, reporting conclusions, preparing for expert witness testimony. Students will set up overnight GSR analysis runs using either the JEOL JSM 6480LV SEM with Oxford Instruments INCA EDS system or the ASPEX 3025 SEM/EDS system. This course provides a foundation for students new to SEM and EDS. At the end of the course, students with no prior experience are able to align an SEM, obtain secondary electron (SE) and backscatter electron (BE) micrographs, and perform EDS qualitative and quantitative analysis. For students with prior experience, we emphasize procedures and strategies to optimize the GSR analysis and data reduction.

Course Outline
  1. Introduction and discussion of GSR Analysis by SEM/EDS course and instrumentation.
  2. Discussion of student’s interest.
  3. Lecture on SEM and EDS theory.
  4. Demonstrations of SEM imaging followed by students “hands on” SEM operation.
  5. Demonstrations of EDS resolution checks, qualitative and quantitative analysis.
  6. Lecture on how to make an in-house GSR standard.
  7. Demonstration and student participation on sample preparation, techniques and equipment.
  8. Demonstrations on instrument setup for GSR analysis.
  9. Practice and participation of students to set up and run overnight GSR analysis on GSR proficiency test samples.
What You Will Learn
  • Given SEM and EDS instruments, the student will setup and operate the instruments successfully.
  • Given SEM instrumentation the student will acquire techniques in obtaining secondary electron and backscatter electron micrographs.
  • Given SEM and EDS instrumentation the student will perform EDS qualitative and quantitative analysis and set up and run an overnight automated GSR analysis.
  • Given appropriate published guidelines the student will interpret GSR analysis results and report conclusions.
