purchased from Sigma Chemical Co. (St. Louis, Mo., U.S.A.). Sample treatment Fish oil (20 g) was aliquoted in 50-mL serum-type reaction vials. The vials were sealed with Teflon rubber septa and aluminum caps. The vials containing the samples were incubated
Quantitative Determination of Acetaldehyde in Foods
For quantification with standard addition, five aliquots (in the range of 1.2–2.0 g) of the sample were weighed with an accuracy of 10 mg into 20 mL headspace vials. After addition of 1.25 mL of SGF and the required acetaldehyde spiking, distilled water up to a total volume of 5 mL was added.

Mushrooms are sources of food, medicines, and agricultural means. Not much is reported in the literature about wild species of the Mediterranean flora, although many of them are traditionally collected for human consumption. The knowledge of their chemical constituents could represent a valid tool for both taxonomic and physiological characterizations. In this work, a headspace

2005/7/15 · It should be noted that, by increasing the sample temperature from 40 to 60 C, the headspace temperature and, accordingly, the temperature of the microdrop solvent would also increase. Since the analyte absorption of the microdrop is an exothermic process, the amount of analytes absorbed by the microdrop decreases upon a further increase in the sample temperature.

2013/11/8 · Headspace gas chromatography is a combination of a sampling technique (headspace (HS)) with a separation technique (gas chromatography (GC)). It allows the analysis of volatile organic compounds (VOCs) in complex matrices without extensive sample preparation and it avoids the problems associated with the injection of dirty samples in a gas chromatograph.
