Mx908 Flashcards
Mx908 uses ______ type of detection
High pressure mass spectrometry
HPMS
How does the MX908 introduce a sample for analysis?
The sample is drawn in through an inlet, either as a vapor or from a swab.
What happens to the sample inside the MX908?
The sample is ionized using a chemical ionization process to create charged molecules.
How does the MX908 separate different ions?
It uses high-pressure mass spectrometry to filter ions based on their mass-to-charge ratio.
How does the MX908 identify substances?
It compares ion signatures to a built-in chemical database.
What categories does the 908 detect?
Explosives
Cwa
Narcotics
Tics
