1.	What must be done to the solid samples for it to be introduced into the column without using solid injection syringes in gas chromatography?(a) Introduced in hot-zone of the column(b) Dissolved in volatile liquids(c) Introduced using rotary sample valve(d) Introduced using sampling loopsThe question was asked at a job interview.I'm obligated to ask this question of Gas Chromatography topic in portion Chromatography of Analytical Instrumentation
Answer» The correct answer is (b) DISSOLVED in volatile liquids The explanation is: SOLID samples must be dissolved in volatile liquids for introducing it into the COLUMN. They can be introduced directly using solid injection SYRINGES.
