Conclusion PLgel columns and the Agilent ELSD are ideal combinations for the determination of poly(lactide-co-glycolide) because of their very low signal to noise ratios and excellent baseline stability. Mixed pore size PLgel columns offer high resolution over a specific molecular weight range. The robust design of the Agilent ELSD allows the nebulizer and evaporator to operate at very high temperatures, efficiently handling the high boiling point solvents that other ELSDs simply cannot manage. PLgel columns and the Agilent ELSD are well suited to the separation of compounds that have no chromophores, under isocratic or gradient conditions. www.agilent.com/chem This information is subject to change without notice. © Agilent Technologies, Inc. 2011 Published in UK, June 9, 2011 5990-8401EN
Authors Greg Saunders and Ben MacCreath Agilent Technologies (UK) Ltd Essex Rd Church Stretton SY6 6AX UK Analyze Injection-Molding Polymers on Agilent PLgel 5 µm MIXED-C by GPC Application Note Materials Testing and Research Introduction Injection-molding thermoplastics are used in a wide variety of applications, including panels for plastic doors, casings for scientific instruments, refrigerator linings, and telephone cases. Ideally, the materials should display excellent weather and impact resistance, good color retention and consistency, resistance to environmental stress, cracking, and high heat resistance. A number of copolymers have been developed that display these properties, such as copolymers of acrylonitrile/styrene/acrylate (ASA) and acrylonitrile/butadiene/styrene (ABS). Typically, these materials are either layered or blended to meet the requirements of a specific application. This application note describes the analysis of a sample of an ASA/ABS-blended material from a car door panel by gel permeation chromatography (GPC), using Agilent PLgel 5 µm MIXED-C columns. Injection-Molding Polymer Analysis Figure 1 shows the blended material that eluted as a single monomodal peak, indicating that the two components of the blend were very similar in molecular size, with an Mw of 160,000 g/mol and a polydispersity of 2.6.
