a)
Interpretation:
The reason why diluted tequila is extracted by four times with dichloromethane rather than one time with a higher volume has to be explained.
To explain the reason why diluted tequila is extracted by four times with dichloromethane rather than one time with a higher volume
b)
Interpretation:
The reason for the usage of on-column injection has to be explained.
Concept Introduction:
On-Column injection:
On-column injection is the best method for quantitative analysis for compounds that are thermally sensitive. It is low resolution technique and doesn’t support for columns with diameters less than 0.2 mm. On-column injection can be used to handle solutions that dilute and concentration in solution both in large and small volumes.
To explain the usage of on-column injection
c)
Interpretation:
The reason for the usage of poly (ethylene glycol) column has to be explained.
To explain the usage of poly (ethylene glycol) column
d)
Interpretation:
The phase ratio
Concept Introduction:
Phase ratio
The volume of mobile phase divided by the volume of the stationary phase is called as dimensionless phase ratio. The phase ratio is calculated as,
