New Language
GSR is now referred to as what?
pGSR
A particle found through automated search that requires further analysis is called what?
Candidate Particle
What is the difference between Major Elements and Level A Elements?
Major elements were 30% or more of the highest peak, while Level A are 50% or more of the highest peak
Which particle type will you always examine first, when detected?
PbBaSb or Characteristic Particles
What is the major difference of the new counts sheet?
You now fill in the particle types based on what you actually relocate
"Gunshot Residue" is now called what?
Primer Gunshot Residue
Any element detected in a candidate particle is called what?
Constituent Element
What is the threshold for level B elements?
10% to 50% of the highest peak
Instead of following the printed/numerical order of PbBaSb particles, how should you choose which particles to relocate?
What two sections have been added to Form C FOR.002 (Write-Up form)?
1. Ammunition Type
2. CC Control Pass?
Two Component Particles are now called what?
Particles Consistent with pGSR
The most intense X‑ray peak of a given element is called what?
Analytical Peak
What is the threshold for Level C?
Less than 10% of the highest peak
True or false: a carbon coating control is not an environmental control
False
One Component Particles are now called what?
Particles with Limited Associations to pGSR
An element that can be found in a pGSR particle is called what?
Element of Interest
What three elements are excluded when determining the most intense peak of the spectrum?
Carbon (C)
Nitrogen (N)
Oxygen (O)
What do you do with any unrelocated particles on a given page?
Cross out the entire area with an X and use code "NR" (not relocated)
If you have 16 fabric PE stubs to collect:
- List the type of EC(s) you will have and the stub type(s) you will use for each
One PE control (carbon stubs)
Two (2) CC controls (fabric stubs)
In testimony, particle type should be explained in terms of what concept?
Commonality
Explain the difference between a constituent element and an element of interest.
A constituent element is any detected element in that particle, while an element of interest is one that can be found in pGSR particles
For .22 ammunition, which two elements (which can normally be A, B, or C) become restricted to only allowable in level C?
Aluminum (Al) and Tin (Sn)
What process that was previously done before relocation should now be done once relocation is complete?
Printing/paginating run sheets
Why don't all Pb/Ba/Sb peaks need to be labeled when taking photos now?
Because they may be present in trace quantities in which all peaks are not visible
