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 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 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 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 the glycerol monostearate (GMS) content and chemically identical antistatic additives in polypropylene where the additive package is known

This compendium describes Agilent materials analysis instruments applications in Polymers and Rubbers

This document describes the GC analysis of total fatty acid methyl esters (FAME) and methyl linolenate in biodiesel using the revised EN14103:2011 method. Four different types of biodiesel samples were manually prepared and analyzed, and the total FAME and methyl linolenate contents were determined with precision exceeding the method’s specifications.

This application note describes a method for detecting residual CHO host cell DNA using the Agilent Mx3005P QPCR System. The method uses sequence-specific primers and probe to detect CHO host cell DNA, producing more specific, sensitive, and faster results than conventional methods such as blot hybridization.

The document introduces a novel dried matrix adsorbent for extracting acidic drugs from blood samples. By optimizing the desorption conditions, the adsorbent can enhance the sensitivity of detecting acidic drugs.

This Application Note describes the transfer of a United States Pharmacopeia (USP) method for prednisolone from normal phase HPLC to SFC using the Agilent 1260 Infinity Hybrid SFC/UHPLC System. The results show that the SFC method meets the system suitability criteria, is 4x faster, and results in 17x lower solvent expenses. Robustness tests on the SFC method demonstrate excellent robustness for routine analysis.

This application note provides detailed instructions on how to use the Stratagene Mx3000P QPCR system to detect and quantify various agricultural and economically important fungi.

This application note demonstrates the performance of the Select PAH GC column for multi-residue analysis

This document describes a multi-residue analysis using an Agilent J&W FactorFour VF-35ms column for PAHs, PCBs, and OCPs. PAHs are compounds with two or more aromatic rings formed during incomplete combustion or pyrolysis of organic matter. OCPs are pesticides containing carbon, hydrogen, and chlorine atoms that break down slowly, persist in the environment, and bioaccumulate in organisms. PCBs are characterized by two phenyl groups with varying numbers of chlorine atoms and are used in various industrial and commercial applications. The method allows for the analysis of 16 EPA PAHs, 17 PCBs (including 6 EU marker PCBs), and 24 common OCPs in a single run at different concentration levels.
