2009/6/1 · Patulin standard stock solution was made in ethyl acetate and stored at −20 C. To make the patulin working solution, an aliquot of patulin stock solution was put into a small amber glass vial and dried under a gentle stream of N 2 gas, then dissolved with acetic acid–water pH 4 (water adjusted to a pH of 4 by acetic acid).

2017/9/1 · The residue was reconstituted with 1 mL of MTBE, filtered using a 25 mm, 0.22 μm PTFE filter (Teknokroma, Spain) into an amber vial for HPLC analysis, and stored at − 80 C until analysis (Vallverdú-Queralt et al., 2013). 2.5.2. Extraction of carotenoids from
export low amounts of N and P; the nitrogen appears largely as dissolved organic nitrogen (DON) and is sourced from decaying vegetative matter (Harris, 2001).
This degradation was observed with amber vials (vial lots 1,2, 4–6, 8, and 9) and, to a lesser extent, with clear autosampler vials (vial lots 3 and 7) and the sample-preparation tubes (vial lots 10 and 11). For some vials, the amount of AA degradation varied among the vials (vial lots 1, 5, 6, and 9,).
In addition, we have established a possible mechanism of action for the larvicidal activity of the essential oil. GC-MS analyses revealed marked differences in the composition of oil that had been freshly isolated and that of a sample that had been stored in a sealed amber-glass vial under refrigeration for three years.
AOZ Std: 6 amber plastic vials, each containing 1.5 ml of the following concentrations of AOZ equivalents: 0 ng/ml; 0.025 ng/ml; 0.05 ng/ml; 0.125 ng/ml; 0.42 ng/ml; 2.5 ng/ml. AOZ Spiking solution 50 ppb: 1 amber plastic vial containing 1 ml of 50 ppb of AOZ.
