Recently I am researching about 2-DIMENSIONAL GAS-CHROMATOGRAPHY; SOLID-PHASE DISPERSION; GC-MS QUANTIFICATION; SUSPECTED ALLERGENS; QUANTITATIVE-ANALYSIS; VOLATILE COMPOUNDS; DYNAMIC HEADSPACE; SCENTED TOYS; VALIDATION; PRODUCTS, Saw an article supported by the Association Nationale de la Recherche et de la TechnologieFrench National Research Agency (ANR). Quality Control of (4-Methoxyphenyl)methanol. Published in WILEY in HOBOKEN ,Authors: Remy, PA; Peres, C; Dugay, J; Corbi, E; David, N; Vial, JM. The CAS is 105-13-5. Through research, I have a further understanding and discovery of (4-Methoxyphenyl)methanol
Two high-resolution mass spectrometers (HRMS) with different analyzer technology, Orbitrap and hybrid quadrupole time-of-flight (QTOF), were compared with a low-resolution mass spectrometer, quadrupole, to analyse a set of 35 difficult allergens. These difficult allergens are commonly coeluted fragrance allergens with matrix compounds, using standard gas chromatography-mass spectrometer conditions, from the extended list of the Scientific Committee on Consumer Safety (SCCS). Although the fundamental role of chromatographic separation has been demonstrated many times, the aim of this work is to demonstrate the benefits of high-resolution. The added value of high-resolution was illustrated in both a qualitative and a quantitative way. For qualitative aspect, the high resolution extracted ion signals of these two detectors were compared with the low-resolution extracted ion signals. About 50% of the coeluted cases observed with the low-resolution detector are easily resolved by the two high-resolution detectors. For the quantitative aspect, an accuracy profile methodology and a performance metric were used to propose an overall evaluation. The Orbitrap mass spectrometer demonstrated a better overall performance, while the QTOF presented similar or even lower quantification performances than the quadrupole on the set of analysed fragrances.
