Methanol and Ethanol are separated in a capillary gas chromatography column with retention times of 370s and 385s, respectively and base width of 16.0s and 17.0s on a column 12.0 m long. An unretained air peak occurs at 10.0 s. (a) Calculate number of theoretical plate and plate height of the column using ethanol peak. Calculate the relative retention. Calculate retention factor for each analyte. (b) (c) (Show your Calculation)
