Oct 05, 2016 · Headspace volatile extraction and analysis. The plantlets (1 g) collected from single clump were carefully cleaned to ensure they were dirt-free and were kept in air-tight, Teflon-coated, screw-capped glass vials. The samples were crushed directly in glass vials by liquid nitrogen to initiate production of headspace oxylipins.

Jan 01, 2020 · Urine samples were prepared in duplicate by adding 900 µL urine to an appropriately labelled headspace vial and 100 µL of the internal standard working solution. Vials were closed with a septa and aluminium crimp cap. The samples were mixed on a vortex mixer and then immediately placed on a headspace auto-sampler tray for analysis. 2.2.5.

2. Experimental method The use of headspace analysis for the measurement of infinite dilution activity coefficients required the assembly of a system of valves for the transfer to the gas chromatograph without contamination or loss of the vapor from the sample cell Žhere a glass sample vial. containing the equilibrium mixture.

In this work, a 20 m × 180 µm id column coated with 1 µm DB-624 was used

Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including
