Question

In comparing open tubular columns to packed columns with a gaseous mobile phase. How many 50 mL extractions will it take to remove 95% of Compound A that is in 20 mL of water, if K=0.3? Assuming that V_aq=50mL and a partition coefficient of K=4, calculate the fraction of the solute that remains in the aqueous phase after four extractions using 25 mL of organic solvent for each extraction. Which is the most common carrier gas of gas chromatography? Solvent trapping is used for Solutes containing halogens con best be studied in gas chromatography with A split injection on a gas chromatograph is normally preferred when An on-column injection is used.
