“…A cotton swatch of approximately 3 x 3 cm (primary material) placed in a clean Petri dish was spiked in the centre with 10 µL of the FM1 using a Hamilton syringe, following the method of Gherghel et al [5]. For the ageing time experiments, the fabrics, in triplicates, were left on the Petri dish from 10 min up to 24 h, with a leftover sample being used for 48 h.…”

“…Gherghel et al [5] developed, optimised, and validated a method able to identify volatile organic compounds (VOCs) from fabrics that had been spiked with perfumes diluted as much as 1500 times in the first study to demonstrate the potential of fragrances for forensic reconstructions. However, a correct identification of VOCs from fabrics is only the first step towards the ability to offer a reliable interpretation of fragrance evidence from clothing [6].…”

Sexual assault is a serious crime that often has low conviction rates. Recent literature has demonstrated that there is potential for fragrances to be valuable in forensic reconstructions where there has been contact between individuals. However, developing appropriate evidence bases for understanding the nature of fragrance transfer in these contexts is needed. This article presents three experiments that address the transfer process of fragrances that have been transferred from a primary piece of fabric onto a secondary piece of fabric, in a manner that could occur during an assault. The three variables studied were the ageing time of the fragrances on the first fabric prior to transfer, the contact time between the two fabrics, and lastly the fabric type (of the primary material and the recipient material). The transfer was evaluated using a validated solid phase micro-extraction gas chromatography-mass spectrometry (SPME GC-MS) method. The findings demonstrated that all three variables had an impact on the transfer of fragrances between clothing fabrics. Generally, lower volatility compounds were transferred and recovered in larger amounts than higher volatility compounds. All fragrance compounds were successfully recovered from a secondary piece of fabric even when the contact time was as short as 10 s, and even when the perfume was aged on the primary fabric for as long as 48 h. The nature of the fragrance transfer also depended on the fabric type, so that a clear discrimination was observed between the fragrance transfer that occurred onto a natural fabric (cotton) and onto a synthetic fabric (polyester).

“…In addition to studies on the composition of perfumes and their stability, latest literature shows the potential of GC-MS for the identification of traces of fragrance volatile organic compounds (VOCs) on clothes of a sexual assault victim or other crime scenes. Due to the close distance between the victim and the attacker, fragrances may transfer between them, so that VOCs can provide valuable information in forensic reconstruction [9][10][11]. Perfume counterfeiting can be also verified based on GC-MS as well as an electronic nose (E-nose) analysis.…”

Perfumes are products that consist of a wide range of natural and synthetic compounds. Due to complex composition, the determination of their ingredients is a difficult task. Most of the perfume components are either volatile or semi-volatile; however, most of the attention has been paid to volatile ones, and thus, gas chromatography or electronic noses are generally used. Nevertheless, in this study, liquid chromatography coupled with mass spectrometry has been applied for direct perfume analysis. Four samples of different best-selling perfumes (two men's and two women's fragrances) and their counterfeits were taken under consideration. The identification of their ingredients was performed by combining obtained results with information available in on-line databases. Compounds specific to essential oils and carrier oils, antioxidants and dyes were generally detected in both types of samples, whereas components of the fragrance of animal origin were only found in brandname perfumes. On the other hand, counterfeits contained more types of polymer emulsifiers. Therefore, based on the results obtained, it can be concluded that liquid chromatography coupled with very sensitive detection technique can be used as a complementary approach to analyses performed with gas chromatography. Moreover, this technique offers the possibility to determine compounds that have low thermostability.

Profiling flavourings in strawberry‐flavoured e‐liquid using headspace‐gas chromatography–mass spectrometry

E‐liquids typically contain nicotine and flavourings in a matrix of propylene glycol (PG) and vegetable glycerine (VG). Some nicotine‐free e‐liquids are flavouring only in the aerosol carrier with the option for users to add their own nicotine. It is only the nicotine that is monitored in terms of level, as specified by the manufacturers. Little is known of the toxicological effect for some of the flavourings in the context of vaping as these are only regulated for ingestion and not inhalation. A method was developed to analyse volatile organic compounds (VOCs) evolved when e‐liquids are vaporised based on headspace‐gas chromatography–mass spectrometry (HS‐GC‐MS) for e‐liquids. An in‐house standard was prepared with sample matrix and purchased strawberry flavouring to simulate a simple e‐liquid but with known levels. This standard was then used to optimise the analysis for use with e‐liquid samples but not for full quantification purposes. These were purchased from a range of retailers and with different batches but mainly focussed on strawberry flavour. The results identified three key components indicative of strawberry flavour (ethyl‐3‐methyl butanoate, ethyl 2‐methyl butanoate and ethyl butanoate) and showed considerable variation between both manufacturers and batches. Flavouring VOCs are regulated for ingestion but are not regulated for e‐liquid inhalation, so these could have toxicological implications. In addition, the inconsistency between samples suggests further issues when users add their own nicotine to the e‐liquids as the viscous sample matrix makes homogeneous mixing difficult.
