“…SPME completely eliminates organic solvents (necessary for cleaning the adsorbent and extraction of the trapped analytes) and simplifies the sampling apparatus, because analytes reach the SPME fiber by passive diffusion and the device pumping the sample through the trapping cartridge can be omitted. Hence the SPME technique can be easily applied in the field [42]. In special applications the SPME fiber can be placed inside the flower and the covering glass vessel usually employed in the charcoal method can also be omitted.…”

A novel Headspace Solid Phase Microextraction (HS-SPME) protocol is proposed for the analysis of floral scent. Volatile compounds emitted from the flower are collected on a Carboxen/PDMS fiber for 1 hour, transferred to the GC, and analyzed by GC/ MS. The method completely eliminates the use of organic solvents, does not require special instrumentation, and may readily be performed in the field without access to mains electricity and other energy supplies. The method is robust, sensitive, and reduces the sampling stress on the investigated plant. Since enzymatic reactions in living flowers may cause changes in the composition of emitted fragrance, dried rosemary (Rosmarinus officinalis L.) was used as a stable standard for the method development and optimization. In addition, grape wine was also suggested as homogeneous, bio-compatible, and relatively stable standard of pronounced and typical scent for the same purpose. The optimized method was used for the comparative investigation of the fragrances emitted by two different species -Lathyrus vernus (L.) and Orchis pallens (L.). Several monoterpenes (C10 compounds) were found as the main fragrance components of lathyrus, while sesquiterpenes (C15 compounds) were typical for the orchid.

“…A previous study indicated that it is possible to preserve an SPME sample over longer periods of time, depending on the SPME coating and the analytes of interest. 24 In this research, a similar approach was used. SPME fibers were retracted ~10 mm inside the needle, sealed with a Teflon narrow-bore cap, and placed on a bed of dry ice (at approximately -20 °C) before sample analysis ( Figure 5).…”

“…57343) were obtained from Supelco (Bellefonte, PA); the fibres were conditioned at 3008C for at least 1 h before use. These fibres were chosen because they have specificity for the compounds of interest, and are well suited for field sampling [16,17]. The lime essential oil was from Citrus limetta rind (Absolute Essential, Auckland, New Zealand) and the manuka (Leptospermum scoparium) oil was a sample of steam distilled manuka extract from an unknown New Zealand supplier.…”

Solid phase microextraction (SPME) coupled with gas chromatography (GC) was used to detect terpene hydrocarbons inside shipping containers entering New Zealand. The utility of this system for the rapid detection of undeclared wood packaging for quarantine purposes was demonstrated. A portable dynamic air-sampling device was built to house a SPME fibre and allow the air from shipping containers to be sampled. The effects of sample flow rate and sampling time were investigated and sampling conditions of 100 mL/min for 30 s were chosen to keep sampling within the linear range. A CV of less than 15% (n = 12) was obtained for all the compounds analysed under these conditions. To obtain an estimate for the limit of detection (LOD) for the terpene hydrocarbons of interest, small quantities of lime oil were placed in an empty shipping container and the air inside was analysed. LOD (S/N = 3) was estimated to be in the order of 50-100 ng/L of air using GC with flame ionisation detection (GC-FID). Finally, the device was tested in fully laden containers and was shown to be effective for trapping terpene hydrocarbons indicative of wood packaging.
