Important safety warnings
There are several important safety notices that you should always keep in mind when using the
Micro GC.
When handling or using chemicals for preparation or use within the Micro GC, all applicable local
WAR N IN G
and national laboratory safety practices must be followed. This includes, but is not limited to,
correct use of Personal Protective Equipment, correct use of storage vials, and correct handling
of chemicals, as defined in the laboratory's internal safety analysis and standard operating
procedures. Failure to adhere to laboratory safety practices could lead to injury or death.
Hydrogen safety
Hydrogen is a commonly used GC carrier gas. When mixed with air, hydrogen can form explosive
mixtures and has other dangerous characteristics.
When using hydrogen (H

explosion hazard. Ensure that the supply is turned off until all connections are made.
Hydrogen is flammable. Leaks, when confined in an enclosed space, may create a fire or
explosion hazard. In any application using hydrogen, leak test all connections, lines, and valves
before operating the instrument. Always turn off the hydrogen supply at its source before
working on the instrument.
•
Hydrogen is combustible over a wide range of concentrations. At atmospheric pressure,
hydrogen is combustible at concentrations from 4 % to 74.2 % by volume.
•
Hydrogen has the highest burning velocity of any gas.
•
Hydrogen has a very low ignition energy.
•
Hydrogen that is allowed to expand rapidly from high pressure into the atmosphere can
self-ignite.
•
Hydrogen burns with a nonluminous flame which can be invisible under bright light.
