The retention indices of 28 C6-C10 and n-C1 1 alkylbenzenes were determined on silicone oil OV-101, UCON LB-550-X, Carbowax 20M and TCEP. Additionally, retention indices of the same compounds on squalane, PEG-4000 and Carbowax 1540 were taken from the literature for quantitative structure-retention
The same wavelength (248 nm) was chosen to analyze all the vitamins since this is the wavelength of maximum absorption of vitamin K1, which is present in very small quantities in vitamin mixes. The other vitamins are relatively poor absorbers at this wavelength but their detection is not compromised
