Analysis of antioxidant behaviour in lubricating oils
Lubricating oils subjected to the operating conditions in an automobile engine degrade by many routes. The most important of these routes is oxidation, which at room temperature and atmospheric pressure is almost immeasurably slow. The performance of a new oil formulation is ultimately assessed by …

Analysis of potent odorants in spearmint oils
… understanding the flavor chemistry of spearmint oils. Potent odorants in Native spearmint, Scotch spearmint, and Macho mint oils were identified by application of gas chromatography-olfactometry (GC-O) and gas chromatography-mass spectrometry (GC-MS). Aroma extract dilution analysis was performed …
