17/7/2014 Optimization of a headspace–solid phase microextraction (HS-SPME) technique for analyzing the volatile profile of almond beverages was performed. An ultra-high temperature (UHT)-treated almond beverage prepared at the pilot plant was used as a model for this kind of vegetable beverage. For the analysis a 2-mL almond beverage, aliquot was used in the presence of salt (NaCl) …

Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such components can also be determined).
Screw Top Vials:Standard (4.6 mm) and large opening (6.0 mm) vials are available in both clear and aer glass. They come with a variety of closures and septa. 9 mm Screw Top Vials:These large opening (6.0 mm) vials have a unique thread design that allows you to screw on the caps, and still use them in a robotic autosampler.
Briefly, an aliquot of 200 μL of a derivatized sample was taken into an insert with bottom spring in an air tight screw capped GC‐MS vials. The analysis was performed by injecting an aliquot of 1 μL of each extract via splitless mode into GC‐MS equipped with HP‐5MS capillary column (30 m × 250 μm i.d . × 0.25 μm film thickness) and electron ionization source (70 eV) at 230°C.

5/4/2018 Fossils entoed in aer are a unique resource for reconstructing forest ecosystems, and resolving relationships of modern taxa. Such fossils are famous for their perfect, life-like appearance. However, preservation quality is vast with many sites showing only cuticular preservation, or no fossils. The taphonomic processes that control this range are largely unknown; as such, we know little

For use with snap caps or aluminum crimp seal closures,these high-quality 11 mm Aijiren glass vials are 2 mL,12 x 32 mm and fit most brands of autosamplers. Made of superior quality 51A (Type 1,Class B),they meet all requirements of US,E
Fill approximately equal quantity of the working standard in 13 aer colored vials. Filling of these vials shall be carried out under reverse laminar air flow. Label these vials month wise, one for each month from the month of preparation. These vials shall be used, one
Headspace vials are available in several sizes (5-27 mL) and styles in clear or aer glass. The most common sizes are 6, 10 and 20 mL. The style and diameter of headspace vials will depend upon your autosampler.The top finish of the vial can be a flat top or beveled finish. Using a beveled finish vial reduced the amount of sealing surface between the crimp seal and the glass surface
30/3/2017 GC-MS and LC-MS/MS analyses Insecticide degradation by the selected microbiota was investigated by cultivating 200 μL 10 5 CFU/mL of each isolate in vials with 50 mL MM9, each containing 10 μg/mL of the insecticide tested.
“C inside rectangle” mark (Photo courtesy of Darlu Littledeer) Although Julian Toulouse illustrates this mark as (apparently) a “C in a square” in his BOTTLE MAKERS AND THEIR MARKS (1971), the original reference which he alludes to is Arthur G. Peterson’s 400 TRADEMARKS ON GLASS(1968) and the shape in Peterson’s book, page 48, is described as a “rectangle”.
