WARNING
Explosive Hazard. If the hydrogen, methane or iso-butane is turned on
without a column attached to the injector and/or detector fittings inside
the oven, the gas could diffuse into the oven creating the possibility of
an explosion.
If the mass spectrometer is not under vacuum, hydrogen, methane or
iso-butane can fill the vacuum chamber thereby creating an explosive
hazard.
To avoid possible injury, do not turn on the hydrogen, methane or iso-
butene unless a column is attached, all joints have been leak-tested, and
the mass spectrometer is under vacuum with the forepump exhaust
properly vented to a fume hood.
AVERTISSEMENT
Risque explosif. Si l'hydrogène, le méthane ou l'isobutane sont
mis sous tension sans une colonne attachée à l'injecteur et / ou
aux raccords du détecteur à l'intérieur du four, le gaz pourrait
se diffuser dans le four en créant la possibilité d'une explosion.
Si le spectromètre de masse n'est pas sous vide, l'hydrogène, le
méthane ou l'iso-butane peuvent remplir la chambre à vide en
créant ainsi un risque explosif.
Pour éviter d'éventuelles blessures, ne pas allumer l'hydrogène,
le méthane ou l'iso-butène, sauf si une colonne est fixée, tous les
joints ont été éprouvés, et le spectromètre de masse est sous vide
avec l'échappement de préchauffage correctement évacué vers
une hotte aspirante.
Recommended Gases
Reagent gases used in chemical ionization (CI) are methane with a minimum purity of
99.999%, isobutene with a minimum purity of 99.98% and ammonia with a minimum
purity of 99.998%. Carrier gas tubing should be ultra-clean.
Methane and isobutene require a gas delivery pressure of 15 psi (104 kPa) to the
bulkhead fitting on the back of the mass spectrometer. A two-stage stainless steel
diaphragm, high purity regulator is. A single-stage stainless steel diaphragm, high
purity, rated for corrosive service is required for ammonia. Clean tubing must be used.
