in polymer formulations. This application illustrates the use of the Agilent 1200 Series Rapid Resolution LC (RRLC) system for the separation of antioxidants and erucamide. The system can operate significantly faster than conven-tional HPLC without sacrificing resolution, precision, or sensitivity. The column chemistry and temperature influ-ence on the separation and the sample preparation
Polymer Additives Primary and Secondary Antioxidants. Practically all polymer materials undergo oxidative degradation reactions occurring at one or all of the manufacturing, processing and end-use stages. Antioxidants are highly effective in preventing this degradation to the extent that color development, physical and mechanical property loss is kept within acceptable limits. The diagram
Antioxidants. Polymers will change over time when exposed to radiation, excessive heat and/or corrosive enviroments. These changes are the result of oxidative degradation caused by free radicals which form through hydrogen abstration or homolytic scission of carbon-carbon bonds when polymers are exposed to heat, oxygen, ozone, or light. These changes can have a dramatic effect on the service

Autoxidation is any oxidation that occurs in presence of oxygen. The term is usually used to describe the degradation of organic compounds in air (as a source of oxygen). Autoxidation produces hydroperoxides and cyclic organic peroxides. These species can react further to form many products. The process is relevant to many phenomena including aging, paint, spoilage of foods, degradation of

Immediately, 1.2 ml milli-Q H 2 O was added to the cell pellet, and, after re-suspension, the samples were sonicated for 30 s (10 watts) on ice (5 cycles × 0.5 min).
These antioxidants are known to diffuse free radicals leading to limited risk of oxidative stress. At cellular and molecular level they inactivate ROS and under specific low concentration inhibit or delay oxidative processes by interrupting the radical chain reaction. Antioxidants also chelate the metal ions responsible for the generation of ROS as they have the potentials to work in both
12 LABORATORY SAMPLE PREPARATION 12.1 Introduction On first impression, sample preparation may seem the most routine aspect of an analytical protocol. However, it is critical that analysts realize and remember that a measurement is only as good as the sample preparation that has preceded it. If an aliquant taken for analysis does not represent the original sample accurately, the results of
Each sample of Swiss chard powder (25 g) was extracted by mixing using a magnetic stirrer with 150 ml of methanol at 30 °C for 5 h. Each extract was filtered through Whatman No. 4 filter paper and re-extracted with the same solvent for the extraction of antioxidant fractions. All extracts were pooled respectively and concentrated under vacuum
