What is the purpose of stretching the skin during sample collection for GSR analysis?
What is the purpose of stretching the skin during sample collection for GSR analysis?
- To prevent any GSR particles from being lost during collection (correct)
- To make the skin more pliable for easier collection
- To hide GSR particles within the folds of the skin
- To make the adhesive tape stick better to the skin
Why is it important to cover the sampled area at least three times during GSR sample collection?
Why is it important to cover the sampled area at least three times during GSR sample collection?
- To hide GSR particles from detection
- To speed up the sample collection process
- To ensure consistency in interpretation of the results (correct)
- To enhance the stickiness of the adhesive tape
What caution should be exercised when using chemical tests for GSR identification if a SEM is not available?
What caution should be exercised when using chemical tests for GSR identification if a SEM is not available?
- The results can be conclusive without further analysis
- The results are always highly specific
- None of the tests are specific, making interpretation challenging (correct)
- Using these tests is unnecessary if a SEM is unavailable
