Time of Flight Mass Spectrometry (1.1.3)
Time of Flight Mass Spectrometry. This is a common form of mass spectrometry, where all particles of the sample to be analysed are ionised to form 1+ ions. These 1+ ions are then accelerated to high speeds, deflected through the spectrometer and then arrive at the detector. As they hit the detector, the mass spectrum graph is produced.
Antimony | Sb | CID 5354495
Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing. However, there are companies in …

Antimony
Antimony forms chemical compounds in three oxidation states: -3, +3, and +5. -3 compounds are called antimonides. They are made by reacting antimony with other metals. They react with acids to make the toxic and unstable gas stibine. +3 compounds are the most common. They are weak oxidizing agents.
