Question
A resolution of _______ is the minimum for baseline peak separation. Which HETP is better, 0.5 mm or 1.0 mm? The main purpose of chromatography is _______ The most common HPLC detector is: ___________ In liquid chromatography, the mobile/stationary phase is always liquid. (circle one). Give the best match for the terms in the first list with the characteristics in the second: ________ normal phase chromatography ______ reverse phase chromatography _________ size exclusion chromatography _______ion-exchange chromatography One common stationary phase is DEAE Mobile phase is more polar than stationary phase Water in sample may cause interference because of its attraction to the stationary phase. Smallest solute particles elute slowly.Explanation / Answer
6. short answers
a. A resolution of 1.0 is minimum for baseline correction
b. HETP of 0.5 is better as it has more number of theoretical plates than 1.0
c. The main purpose of chromatograohy is separation of components in a mixture
d. Most common HPLc detector : UV-VIs
e. In liquid chromatography, the obile phase is always liquid
7. Best match
normal phase chromatography : B.
Reverse phase chromatography : C.
size exclusion chromatography : D.
ion-exchange chromatography : A.
