Using nuclear magnetic resonance (NMR) technology effectively identify fake perfume
"We are the data obtained from the study showed that the 1 h NMR fingerprint can be used as an alternative approach to identify counterfeit products"
Magnetic resonance spectroscopy (NMR) is a complex mixture of proven analysis, can be identified in an analysis of all components.The technology now is used to identify true and false perfume for the first time.
Success may be perfume market, its global value reached $31.4 billion in 2018.Online sales growth to ensure the sustainability of its growth, it is mainly due to the perfume has become more and more popular among young people.Perfume into the online retail platform, however, provides a more fake perfume sales opportunities.
Unscrupulous businessmen not to use expensive oil to make want to smell, but using cheap synthetic chemicals instead of essential oils, expensive perfume of famous brand to fake.Fake perfume sales price is lower than the real thing, its packaging and quality goods butch, thus deceiving unsuspecting consumers.Consumers are not the so-called value, but spend high price to buy the cheap perfume that may contain toxic or irritating chemicals.Counterfeit goods did not pass quality goods required safety assessment, therefore, the impact of its use is unknown.So, the pressure is to be able to easily identify fake perfume, so that its removal from the market, so as to protect consumers and reputable manufacturers.
While in the aspect of artificial electronic olfactory system were used to detect fake perfume has had some success, but these systems can only detect volatile components, thus limited.Therefore, nuclear magnetic resonance (NMR) spectroscopy is regarded as a potential tool comprehensive characterization of perfume.By getting the real thing the NMR spectrum of perfume, can be based on the analysis of unknown samples, comparing the spectrum to identify cheap imitations.
In a recent study, researchers used equipped with broadband BBI 5 mm probe brooke Avance II Plus 700 MHz nuclear magnetic resonance spectrometer, obtained a series of original perfume, 1 h NMR spectrum.We have analyzed in a similar way the perfumes of counterfeit goods, and use the spectrum data of main component analysis and linear regression method to compare the resulting spectrum.All chemometrics analysis is made on brooke software package.Fake perfume ingredients and there are considerable differences in their original perfume.The results revealed that the obvious signs of counterfeit products, even not by dilute the original production.In addition, the components that exist in the counterfeit products suspected will pose a threat to the health of consumers.
The new study supports the 1 h NMR fingerprint as a identify fake perfume and feasible method and rapid, against unscrupulous marketing inferior imitation.
Brooke unique solutions enable the authorities to effectively combating counterfeit product again and enhance the safety of consumers.
