How is a sample converted to a gas in GC?

Howdy,

I'm working on some homework, and I was wondering if anyone here knew exactly how a liquid OR a SOLID sample is converted to a gas to be analyzed in GC? I figure that a liquid is converted to a gas via flash evaporation (hot injection port)...it is vaporized and then carried into the column by the carrier gas (helium). But can a solid sample be converted to a gas?

Thank you so much,

With great power comes great responsibility.

Yes, solid samples, if they're small enough molecular weight, will quickly melt and vaporize, and be amenable to GC assay. Examples would include chloroxylenol, BHT.
