APPLICATION NOTE
Introduction Uranium-236 (236U) is the product of thermal neutron capture of 235U, but the natural occurrence of 236U is very rare. The presence of this isotope in a sample of uranium indicates that the sample originates from a nuclear reactor. Compared …
APPLICATION NOTE
Introduction Diesel exhaust fluid (DEF), alternatively called AUS 32 and marketed as AdBlue is a diesel fuel additive that is stored separately from the car’s fuel tank. To comply with Euro 6 regulations, diesel cars use a Selective Catalytic Reduction …
APPLICATION NOTE
Introduction Per- and polyfluoroalkyl substances (PFAS) are man-made carbon-chain based compounds that have been widely used in commercial and industrial products such as fire-fighting foams, water proofing treatments for clothing and furniture, …
APPLICATION NOTE
Introduction Pyrethroids are a type of synthetic insecticides that work by attacking arthropod insects’ nervous system, with a knockdown and cidal effect that is up to 100 times higher than that of older generation insecticides, such as organochlorine …
APPLICATION NOTE
Introduction The elemental concentration of fluid inclusions in geological samples provides information about geological processes that lead to the formation of ores and minerals. Laser ablation-ICP-MS (LA-ICP-MS) is the preferred technique for …
APPLICATION NOTE
Introduction Epoxy resins, in the category of CASE chemicals and materials, are not only used for moisture barrier applications, but they are also commonly used for adhesive purposes. The strong properties of epoxy allow for structural and engineering …
APPLICATION NOTE
Introduction For more than 40 years, the United States Environmental Protection Agency (EPA) has monitored semivolatile organic compounds (SVOC) in wastes, soils/sediments, and groundwater via its Method 8270. This method is extensive in scope, …
APPLICATION NOTE
Introduction To protect the integrity of semiconductor and electronics end-products, semiconductor researchers and developers (R&D) and manufacturing QA/QC functions face unique challenges to reduce contaminates, sometimes down to ultra-trace levels. …
APPLICATION NOTE
Introduction Dynamic Mechanical Analysis (DMA) is one of the most appropriate methods to investigate relaxation events. Rubbery samples are normally examined in either shear or a bending geometry. This note examines single cantilever bending and how the …
APPLICATION NOTE
Introduction Isothermal crystallization is a sensitive test and can be used to show the difference between various batches of material, which may show little difference under a conventional heating experiment. For polymer resin manufacture, it can be …
Q&A
Introduction It’s no surprise that insourcing highly skilled scientific staff can be a smarter approach to optimizing lab workflow. With increasing pressure to discover and deliver new drugs at a faster pace, it’s crucial to find the right strategic …
APPLICATION NOTE
Introduction Thermogravimetric analysis (TGA) is one of the members of the family of thermal analysis techniques used to characterize a wide variety of materials. TGA provides complimentary and supplementary characterization information to the most …
APPLICATION NOTE
Introduction High-density polyethylene (HDPE) is a commonly recycled plastic, notably from plastic drinking bottles. Recycled applications of HDPE are many and various including new packaging and textile fibres. But it is especially valued in automotive …
APPLICATION NOTE
Introduction This application note provides methodologies and results on TGA analysis of a range of polymeric material samples including printed circuit boards, toothbrush bristles, and plastic bottles. Thermogravimetric analysis (TGA) is one of the …
APPLICATION NOTE
Introduction In order for manufacturers and users to control the quality of products, it is necessary to identify polymers and build a polymer library. Since the 1980s, the combination of thermal pyrolysis and gas chromatography-mass spectrometry (GCMS) …
APPLICATION NOTE
Introduction A valuable application of thermal analysis (TEA) is for the characterization of electronic materials and components, including printed circuit boards (PCB) and encapsulants. The key properties that TEA can help address are softening …
APPLICATION NOTE
Introduction Polymer blends are widely utilized for a variety of applications as the particular thermo-physical properties of the individual components comprising the blend result in better overall properties. This is particularly the case of polymer …
APPLICATION NOTE
Introduction One of the more commonly used thermoplastics is polypropylene because of its versatility. As with all thermoplastics, it is important to characterize the thermophysical properties of polypropylene, including melting temperature, percent …
APPLICATION NOTE
Introduction This compendium provides example data and interpretations for the seven codes of recyclable polymers. DSC and TGA raw data files are provided so that the user can easily overlay their data with the expected results for new unprocessed …
APPLICATION NOTE
Introduction PVDF (Polyvinylidene fluoride), along with other polymers such as SBR and PTFE, is commonly used as a binder in the anode of lithium-ion batteries due to its electrochemical and chemical stability, and high adhesion to the current …
ARTICLE
Introduction Pharmaceutical and life sciences companies now face heightened scrutiny over their practices in documenting their electronic processes in particular, and in managing that data across its entire lifecycle. Looking ahead, lab efficiency and …
APPLICATION NOTE
Introduction Biodiesel, also referred to as fatty acid methyl ester (FAME), is a renewable and biodegradable fuel manufactured from vegetable oils, animal fats as well as recycled cooking greases and oils. A quick and accurate test method is highly …
