Assignment:
Calculate:
Q1. Corrected retention times for air and 3 alcohols
Q2. Specific retention volumes for 3 alcohols
Q3. Distribution constant for 3 alcohols
Q4. Capacity factor for 3 alcohols
Q5. The average number of theoretical plates and the average height of a theoretical plate for the column.
Given:
1. Column length: 1.1m ID = 2mm
2. Weight of stationary phase = 1.4g /density = 1.02g/ml
3. Average volumetric flow in column = 30.2ml/min
4. Inlet pressure = 26.1psi above ambient press
5. Room temperature = 21.2C column temp = 102C
RETENTION TIMES:
air = 0.3 min
propanol = 2 min
butanol = 4.2 min
hexanol = 8 min
PEAK WIDTHS:
propanol = 0.2min
butanol = 0.4 min
hexanol = 0.8min.
Provide complete and step by step solution for the question and show calculations and use formulas.
