GC ALS AND GC HS Difference injection technique,
GC ALS Inject the liquid and small volume (like 0.2,0.5 or 10ul)
GC HS inject the vapour directly large volume (1ml)
ALS solid must be dissolve solvents but HS Use diluent water also.
ALS Inject solvent including product but HS Inject only vapour stage of solvent.

2. Two grams of Benzoic acid are dissolved in 200 ml of water and extracted with 200 ml of diethyl ether. The distribution coefficient of benzoic acid is 100, and its dissociation constant is 6.5 10-5. Calculate the distribution ratio (D) of benzoic acid at pH 2, 5, and 6. 3. Calculate D at pH 2 to 10 (1 unit apart) in the above problem, and plot D versus pH.
