Improvement of the quality of analytical results generated by GC/MS method for characterization of Helichrysum italicum (Roth) G. Don essential oil
Most of the papers that treat the composition of essential oils for this purpose use GC/MS or GC/MS and GC/FID techniques for the identification and/or quantification of individual compounds. Therewithal, papers usually treat the composition as semiquantitative (percentage composition as the area of the peak of a particular compound in relation to the total area of the peaks on the chromatogram, given as 100 %). At the same time, the quality of the results is not treated in metrological terms. A GC/MS method for the quantification of components present Helichrysum italicum hydro-distilled essential oil samples from Bosnia and Herzegovina with a similar composition was developed and optimized. The stability of the method setup and adequacy of sample storage and manipulation were assessed. Calibration method and assessment of measurement uncertainty were established for neryl acetate, one of the major compounds with known health benefits.
期刊介绍：
Accreditation and Quality Assurance has established itself as the leading information and discussion forum for all aspects relevant to quality, transparency and reliability of measurement results in chemical and biological sciences. The journal serves the information needs of researchers, practitioners and decision makers dealing with quality assurance and quality management, including the development and application of metrological principles and concepts such as traceability or measurement uncertainty in the following fields: environment, nutrition, consumer protection, geology, metallurgy, pharmacy, forensics, clinical chemistry and laboratory medicine, and microbiology.
