Recently the miniaturization of liquid chromatography (LC) systems and progresses in mass spectrometry instrumentation have enabled direct introduction effluent coming from a nanoLC column into high-vacuum region an electron ionization source. In present research, system was directly coupled to spectrometer (EI-MS) without any interface or modification ion The advantage with respect atmospheric pressure techniques, normally LC, is major identification power because more extensive...
The present research is focused on the evaluation, in terms of efficiency and polarity, a recently introduced gas chromatography (GC) column, coated with 1,12-di(tripropylphosphonium) dodecane bis(trifluoromethansulfonyl) amide ionic-liquid stationary phase (SLB-IL59) its application to analysis complex essential oil. ionic liquid column demonstrated very good efficiency, plate number, polarity close that 100% poly(ethyleneglycol) phase. In this preliminary SLB-IL59 30 m was subjected...
In this work, two analytical liquid chromatography methods were developed and compared for the characterization of aqueous phases from pyrolysis lignocellulosic biomasses. NanoLC electron ionization-mass spectrometry (EI-MS) represents a novel useful tool both separation identification semi/nonvolatile thermolabile molecules. The use nanoscale flow rates, highly reproducibility, high detailed information on EI spectra are principal advantages technique. On other hand, comprehensive 2D-LC,...
White truffle (Tuber magnatum Pico) is one of the most valuable delicacies Italian and French cuisine. Previous works on aroma report sulfur compounds short-chain aldehydes as typical constituents which abundance influenced by storage conditions. In this study, head space has been evaluated two different (innovative) approaches: HS-SPME extraction comprehensive two-dimensional gas chromatography (GCxGC), exploiting a dual-stage loop-type modulator within GC system with simultaneous FID MS...
This research aimed to support police forces in their battle against illicit drug trafficking by means of a multi-technique approach, based on gas chromatography. In detail, this study was focused the profiling volatile substances narcotic Cannabis sativa L. flowering tops. For purpose, Scientific Investigation Department, RIS Carabinieri Messina, provided 25 seized samples The content Δ9-tetrahydrocannabinol (THC), useful classify cannabis plant as hemp (≤ 0.2%) or marijuana (> 0.2%),...
Abstract Cold‐pressed mandarin essential oils are products of great economic importance in many parts the world and used perfumery, as well food products. Reconstituted easy to find on market; useful information oil authenticity, quality, extraction technique, geographic origin biogenesis can be attained through high‐resolution GC volatile fraction, or enantioselective GC, using different chiral stationary phases. Stable isotope ratio analysis has gained considerable interest for unveiling...
Abstract The bitter orange tree is used to obtain different products: essential oil cold pressed from the peel of fruit, neroli distilled flowers, petitgrain leaves and twigs, other products obtained by solvent extraction or hydrodistillation. All these are much appreciated for their odor properties. Their analytical characterization important Identification quality parameters, considering commercial value, it determine composition. This study meant differences between Italian Egyptian...
An investigation into cold-pressed finger lime essential oils (Citrus australasica) was conducted utilizing both liquid and gas chromatographic techniques. Samples were collected throughout the entire productive season, spanning from October 2022 to June 2023. This research aimed elucidate composition of non-volatile oxygen heterocyclic components using RP-HPLC-QqQ/MS analyze volatile fraction GC-FID. Additionally, enantiomeric ratios selected determined through multidimensional GC (MDGC)...
Abstract In the present research, chemical composition of volatiles in fresh leaves and twigs Pistacia lentiscus L. was determined by using GC–FID GC–MS. past years oil employed perfumery, food pharmaceutical industries, while recently it has been re‐evaluated as a flavouring alcoholic beverages chewing gums, due to natural production exudate called ‘mastic gum’. The study carried out on Sicilian plants with aim integrating already existing information oil. samples were obtained traditional...
A novel preparative-scale triple gas chromatographic system, equipped with three Deans-switch devices, is herein described. The isolation of volatile compounds was achieved by using a lab-made collection system. Considerations are made on the possibility to inject high volumes neat sample, maintaining, at same time, resolution levels. degree recovery series compounds, characterized differing volatility, also reported. In this respect, different conditions were evaluated, namely, presence (or...
Mineral oils, which are mainly composed of saturated hydrocarbons and aromatic hydrocarbons, widespread food contaminants. Liquid chromatography coupled to gas with flame ionization detection represents the method choice determine these two families. However, despite high selectivity this technique, presence olefins (particularly squalene its isomers) in some samples as olive does not allow correct quantification mineral oil fraction, requiring additional off‐line tools eliminate them. In...
