  • anu ba ung carrier gas

    or mobile phase?

    anu bang gngawa nun?

    eh ung stationary phase?

  • Kadalasan, ang carrier gas (mobile phase) ay noble gas tulad ng He. Basta hindi siya magrereact yung gas sa sample mo, pwedeng gamitin yung gas para sa mobile phase. Ang ginagawa ng mobile phase ay tinutulak nito yung gas (or liquid in the case of HPLC) patungo sa column (stationary phase).

  • Ang stationary phase naman ay yung column kung saan dumadaloy yung gas (or liquid in the case of HPLC). Yung column ay may maliliit na beads gawa sa silica (neutral). Habang tumatagal, bumabagal ang pagdaloy nung gas sample sa column dahil kailangan nitong mag-undergo ng equilibrium. At dahil ang bawat kemikal ay may bukod-tanging equibrium constant, malalaman natin kung ano ang laman nung gas sample base sa kung gaanung katagal siya dumaloy sa column.
