Generalized schematic of the NMGRL Extraction System and Mass Spectrometer.
(please click on one of the red objects to learn more about it)

The NMGRL Extraction System consists of:
RED	Heating devices	Furnace, CO2 Laser, UV Laser and Crusher.
PALE YELLOW	Pumps	Four V-70 Turbomolecular pumps backed by primary pumps.
ORANGE	Furnace Loader	Auto loader capable of depositing 17 individual samples into furnace.
GREY	GP-50 Getters	Metallic getters "trap" all non-noble gas molecules leaving only argon and other rare gases.
BLUE	Air Pipette	Bottle of atmospheric argon necessary for determining isotopic discrimination.
GREEN	Quadrupole	Quadrupole mass spectrometer; ideal for pre-sampling of argon, leak detecting.
GREEN/RED	Ion gauges	Necessary to monitor pressure of ultra-high vacuum.
