a)
Interpretation:
The Kovats retention index for the unknown has to be calculated.
Concept Introduction:
Kovats retention index:
Retention index, I for linear
For a molecule of Octane,
For a molecule of Nonane,
The elution of compound between Octane and Nonane will have retention index between 800 and 900 is calculated using the formula,
Where,
To calculate the Kovats retention index for the unknown
b)
Interpretation:
The Kovats retention index for the unknown has to be given if the phase ratio of the column were doubled.
Concept Introduction:
Kovats retention index:
Retention index, I for linear alkane equals 100 times the number of Carbon atoms.
For a molecule of Octane,
For a molecule of Nonane,
The elution of compound between Octane and Nonane will have retention index between 800 and 900 is calculated using the formula,
Where,
To give the Kovats retention index for the unknown if the phase ratio of the column were doubled
c)
Interpretation:
The Kovats retention index for the unknown has to be given if the length of the column were halved.
Concept Introduction:
Kovats retention index:
Retention index, I for linear alkane equals 100 times the number of Carbon atoms.
For a molecule of Octane,
For a molecule of Nonane,
The elution of compound between Octane and Nonane will have retention index between 800 and 900 is calculated using the formula,
Where,
To give the Kovats retention index for the unknown if the length of the column were halved
