Feb 04, 2019 · The same pump was used as in Figure 5, but now with a column (30 mm x 2.1 mm i.d. Aijiren SB-C18) in use, and gradient elution. Solvent A is 0.1% trifluoroacetic acid in water, solvent B is 0.1% trifluoroacetic acid in acetonitrile, and the gradient runs from 2 to 40% B in 4 min. [1]
The more recent on‐line HPLC‐GC‐FID method 4 was intended for routine analysis and does not separate the MOAH into groups. The edible oil or crude food extract is injected into a 25 cm×2 mm id silica gel HPLC column, which retains the lipids in the upper part and separates the MOAH from the MOSH in the lower.
Jun 29, 2020 · IS (10 μL) was added to 100 μL of rat plasma in a 16 mm × 150 mm glass tube. Then, 300 μL of cold acetonitrile (−20°C) was added, followed by vortex mixing for 1 min. HPLC‐grade water (300 μL) was then added and vortex mixed again for 1 min (Zgair et al., 2015).
Autosampler Vials, Caps and Closures Thermo Scientific™ 11 mm Glass Crimp Top Vials Use these 11 mm clear glass vials with snap caps or aluminum crimp seal closures.
sample vial was vortex mixed and placed in an ultracentrifuge (Eppendorf Micro Centrifuge 5415C) at a relative centrifugal force of 12,600 g for 10 minutes. The extract was transferred to a sample vial with a 0.350 mL insert (Supelco, Bellefonte, PA), capped, and analyzed by high performance liquid chromatography (HPLC).
