NH4 ions are usually generated from ammonia or ammonium-containing chemicals. We herein present a simple method for generating NH4 reagent ions in the hollow cathode glow discharge ion source that nowadays most proton-transfer-reaction mass spectrometry (PTR-MS) instruments are equipped with. We ...

In summary, NH4HS can react with strong bases, such as NaOH and KOH, to produce ammonia (NH3) and the corresponding salts (NaHS or KHS). However, when NH4HS is dissolved in water before reaction, hydrolysis may occur, leading to the formation of ammonium hydroxide (NH4OH) and hydrogen su...
All extracellular NH4+ actions were observed at concentrations as low as 0.3 mM and the neurons reacted immediately after ammonia arrived the slice. We propose that a brief augmentation of neuronal activity by NH4+ may occur either spontaneously during arousal or induced by inhalation of ...
