This method is for the determination of the glycerol monostearate (GMS) content and chemically identical antistatic additives in polypropylene where the additive package is known

This method is for the determination of the number of vinyl groups (C=C) in polyethylene resins by infrared spectroscopy. The test is used primarily for resins made with chromium catalyst technology, which gives a vinyl group at the end of each polymer chain, rather than resins made with titanium-based catalysts, which have few unsaturation sites. The method is applicable to powder, pellets or pieces cut from finished parts, but cannot be used for filled or pigmented samples.

This method is for the determination of Irganox 1010 and chemically identical antioxidants in polyethylene where the additive package is known. The method utilizes a characteristic ester carbonyl band associated with the additive that is common in many other additives. Therefore, the total additive package must be known to confirm that other additives present do not contain bands that would interfere with the measurement. The method is typically used for process control of additive addition and is not recommended for filled or pigmented resins. The sample must be pressed into a film or coupon prior to the analysis.

This method is for the determination of the statistical or randomly distributed ethylene content of ethylene-propylene copolymers. The determination is specific for ethylene and cannot be applied for the quantitation of other comonomers. The method has been validated over the range of 0.3 to 3.5% statistical content and can be used for either powder or pellet samples. Certain sorbitol-based clarifiers have been found to interfere with the determination and therefore a correction factor is necessary for resins containing these additives. This method is generally not recommended for quantitation of ethylene in filled or pigmented resins.

This method is for the determination of Irganox 3114 and chemically identical antioxidants in polypropylene where the additive package is known. The method utilizes a characteristic carbonyl band associated with the additive that is common in many other additives. Therefore, the total additive package must be known to confirm that other additives present do not contain bands that would interfere with the measurement. The method is typically used for process control of additive addition and is not recommended for filled or pigmented resins. The sample must be pressed into a film or coupon prior to the analysis.

This application note introduces the basic principles and techniques of atomic force microscopy (AFM) spectroscopy and discusses various methods for AFM spectroscopy. The application note also provides examples of how to use AFM spectroscopy techniques to study various materials and applications.

This application describes the development of a liquid chromatography/tandem mass spectrometry (LC-MS/MS) method for the determination of estrone-3-sulfate (E1S) in water with a sensitivity below the ppt level (< ng L-1). The method involves solid-phase extraction (SPE) and liquid chromatography/tandem mass spectrometry (LC-MS/MS) in negative electrospray mode. The method achieved high recoveries (>93%) and low detection limits (<1 pg L-1). In addition, the method was highly selective, with no interferences from other compounds observed. This makes it a suitable method for the analysis of E1S in environmental water samples.

This Application Note describes the application of ternary and quaternary gradients in reversed phase chromatography. Ternary and quaternary gradients are rarely used in method development, but they can be very helpful in finding optimized conditions for a separation. In this Application Note, binary, ternary, and quaternary gradients are applied and compared. Performance data, including resolution and precision of retention time are evaluated and the results show that these gradients are a useful tool.
