“…This is because the extraction process was carried out at a maximum temperature of 100°C. Based on our previous work, elemental analysis (including Br) of the leaves of the M. longifolia samples has been quantified, and the present essential oils samples have been extracted from the same M. longifolia leave samples. A comparison between the elemental concentrations in the leaves of M. longifolia samples and that found in the extracted essential oil was carried out.…”

Direct analysis of essential oil has been performed for estimation of the elemental content in five different extracted essential oils from the leaves of different plants, namely, Mentha longifolia, Rosmarinus officinalis, Ocimum basilicum, Elletaria cardamomum, and Lavandula hybrida. A benchtop total reflection X-ray fluorescence spectrometer with a maximum power of 40 W was used for this purpose. Fourteen elements have been quantified in most of the extracted essential oil samples, and their limits of detection were determined. The detected elements are P, S, Cl, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, As, Br, Ni, and Hf. The validity of the present method was demonstrated using a standard reference material of organometallic oil sample. Two extraction methods of essential oils from leaves of the mentioned plants are evaluated, namely, classical hydro-distillation and microwave-assisted hydro-distillation. The quantitative elemental analysis of the extracted essential oils using the two extracted methods was studied and compared.

“…Afterward, the extracted essential oils were reserved in the brown glasses and kept in −20°C refrigerator until further chemical investigation. In order to stabilize the extracted essential oil samples on the quartz reflector, 5 μl of silicone solution was deposited centrally and dried before the deposition of the oil samples …”

“…Yuan et al 251 isotope ratios was demonstrated by multiple spot analyses by LA-MC-ICP-MS. External precisions were <0.026% for 207 Pb/ 206 Pb and 208 Pb/ 206 Pb and <0.057% for 206 Pb/ 204 Pb, 207 Pb/ 204 Pb and 208 Pb/ 204 Pb (2RSD). The precision for 34 S/ 32 S (2SD) was <0.41%.…”

“…The performance of silicone-coated silicon reflectors was superior 206 to that of reflectors coated with poly(vinyl alcohol) for the TXRFS analysis of plant materials. Digests (HNO 3 -H 2 O 2 ) of Mentha longifolia L. leaves collected from different cities in Saudi Arabia were applied to the reflectors and 15 elements quantified.…”

“…The use of multiple ion counters for U-Pb dating of zircons by LA-MC-ICP-MS made 268 it possible to date zircons with a 238 U signal of <0.5 mV with improved spatial resolution. The 202 Hg, 204 (Pb + Hg), 206 Pb, 207 Pb, 208 Pb, 232 Th and 238 U isotope signals were measured simultaneously on only ion counters unlike previous studies that had used both ion counters and FCs. Tiny zircons and grains with small cores or narrow zonation could be analysed since three laser pulses (beam diameters 5 µm) consumed <5 ng of zircon.…”
