Positive match with a library spectrum

Question 7

What are the First Defender and TruDefender intended to provide?

Answer 7

Presumptive identification of a material of interest

Question 8

What three sorts of materials cause problems for the First Defender?

Answer 8

Explosive and flammable materials may be activated by the device’s laser; highly fluorescent materials can obscure the RAMAN signal; non-covalently bonded materials may not generate enough signal to be identifiable

Question 13

What is the primary purpose of the MultiRae Pro?

Answer 13

Determine presence of atmospheric hazards in an area of interest

Question 14

What does a “yellow” result in the First Defender or TruDefender indicate?

Answer 14

Close match, but an additional method of identification is needed

Question 15

What can affect the transmission of UV light needed to get accurate readings from the PID?
