Identification of the compounds was performed by comparing the mass spectrum with that of the library NIST 2.0 (2009), by the relative retention index (RI), calculated according to Van den Dool & Kratz (1963), and compared with information in the literature (Adams, 2012).

Positive identification was considered only when both mass spectrum and retention index were in good agreement with library data [25].
They cover theory and applications of non-equilibrium thermodynamics in nonlinear chromatography and electrophoresis, biomimetic chromatography as a useful tool in drug discovery, solid-phase microextraction for in vivo pharmacokinetics and other stages of drug development, identifying and detecting antibiotic drugs and their degradation products in aquatic samples, preparing samples for chromatographic analysis, developing HPLC retention index QSAR models for non-targeted metabolomics, and thin-layer chromatography with a controlled gas phase influencing the separation.
"We have noticed a high growth in the Customer Satisfaction and customer retention Index and have made extensive efforts in the past several years to reach out to more and more customers through various showrooms and service centres across the country and this award is recognition of all our good efforts," he added.
The perceived odors were attributed to the odorants identified in the preceding experiments using the solvent extract, by means of odor quality, odor intensity, and retention index [3].
The benzene eluent from the column fractionation (the fraction containing aromatics) was examined by establishing the retention index from the literature and standards injection.
