Analysis of rubber by pyrolysis GC/MS.Routine analysis requires automation due to the increasing demand for shorter analysis times, higher throughput and cost reduction, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the company. The Pyromat allows users to load up to 24 samples for unattended analysis. All parameters such as temperature, pyrolysis py·rol·y·sis n. Decomposition or transformation of a chemical compound caused by heat. pyrolysis (pīrol´isis), n time and gas chromatography gas chromatography (GC) Type of chromatography with a gas mixture as the mobile phase. In a packed column, the packing or solid support (held in a tube) serves as the stationary phase (vapour-phase chromatography, or VPC) or is coated with a liquid stationary phase (GC) conditions can be defined for each sample, if required. The Curie-Point-Pyrolyser can be installed or removed from the GC in just a few minutes. In this way, users are said to be able to easily change, reliably and safely, between pyrolysis and liquid injection. The advantage of Curie-Point-Pyrolysis is said to be the use of ferromagnetic Refers to a material, such as iron and nickel, that can be easily magnetized. See MRAM. material which heats up in a very short time inside a magnetic field to a defined Curie-Point temperature. With increasing temperature, the permeability of ferromagnetic materials is said to decrease. At the Curie-Point, the relative permeability of the sample carrier falls suddenly and the status changes instantaneously from ferromagnetic to paramagnetic par·a·mag·net·ic adj. Relating to or being a substance in which an induced magnetic field is parallel and proportional to the intensity of the magnetizing field but is much weaker than in ferromagnetic materials. . Pyrolysis temperature may be controlled by selection of the composition of the sample carrier, e.g., pure iron has a Curie-Point temperature of 770[degrees]C and nickel 358[degrees]C. Through the selection of different alloy compositions, Curie-Point temperatures can be provided from 160 to 1,040[degrees]C in ca 15[degrees] steps.
