[USPRwire, Fri Apr 26 2019] Methyl silicone is used in transportation, construction, electronics, energy, healthcare, industrial processes, and personal care industry, amongst many others.
The qualitative analysis of the Dodonaea viscosa was performed with Gas Chromatography using flame ionization detector (FID) with a less polar capillary column OPTIMAA(r)-5-Accent (60 m x 0.32 mm ID with film thickness 0.25um of 5% Phenyl / 95% Methyl Silicone) installed on a Shimadzu GC-10.
An HP-5MS capillary column (30 m x 0.25 mm coated with 5% phenyl methyl silicone, 95% dimethylpolysiloxane, 0.25 [micro]m film thickness) was used.
Separation was achieved on an RTX 65-TG capillary column with a 65% phenyl methyl silicone HT (TG) stationary phase (Restek, Bellefonte, CA, USA) (l = 30 m, i.d.
An elastic quartz capillary column (DB5MS; 30 m x 0.25 mm x 0.25 1/4 m) coated with a neutral phase (Hewlett-Packard-5 cross-linked 5% phenyl methyl silicone) was used.
