Volatile

volatile

1. Passing through the air on wings, or by the buoyant force of the atmosphere; flying; having the power to fly.

2. Capable of wasting away, or of easily passing into the aeriform state; subject to evaporation.

substances which affect the smell with pungent or fragrant odors, as musk, hartshorn, and essential oils, are called volatile substances, because they waste away on exposure to the atmosphere. Alcohol and ether are called volatile liquids for a similar reason, and because they easily pass into the state of vapor on the application of heat. On the contrary, gold is a fixed substance, because it does not suffer waste, even when exposed to the heat of a furnace; and oils are called fixed when they do not evaporate on simple exposure to the atmosphere.

3. Light-hearted; easily affected by circumstances; airy; lively; hence, changeable; fickle; as, a volatile temper. You are as giddy and volatile as ever. (swift) Volatile alkali.

(Science: chemistry) See essential oils, under Essential.

Origin: F. Volatil, L. Volatilis, fr. Volare to fly, perhaps akin to velox swift, E. Velocity. Cf. Volley.

MALDI; fusion protein cleaving from a peptide

You have lot's of non-volatile substances, which may cause troubles in mass spec. But I'm not expert in this area. Do you have linear or reflected TOF? Because you could be at the limit of your machine with 3 kDa. Anyway, I would rather ...

Re: Theories - Origin of Life

... because the spark was in the atmosphere and he'd used up all of the chemicals with carbon in the atmosphere, and the amino acids, which aren't volatile — they don't fly, so to speak — were safely ensconced in the water solution, and the water solution was a collection of non-volatile compounds, ...

Re: DUMAS METHOD OF DETERMINING MOLAR MASS OF A VOLATILE LIQUID

Thanks for all your input guys. I am just finishing my lab report right now. This is off topic, but do you guys know a good website where I could get some lab gear, more specifically a light microscope? Thanks.

Re: DUMAS METHOD OF DETERMINING MOLAR MASS OF A VOLATILE LIQUID

Yes, the whole point was to convert the methanol into a gas, that is why we are using this equation in the first place. The volume I am using in these equations are the volume of the flasks we have been using not the volume of the methanol. When it comes to molarity we weren't given it in this exper...
