Torch Fixed 1.5mm Injector 1 Pin 450-01

DescriptionTorch Fixed 1.5mm Injector 1 Pin 450-01Part Number: PG450-01Cross Reference(s) Thermo: 3600969Instrument Compatibility: Thermo X-Series Thermo X-Series 2Detail: Quartz, Fixed 1.5mm ID injector, single locator pin, 12/5 Ball.What Makes the Torch Work?Plasma forms at the end of three concentric quartz tubes, collectively known as the torch. Argon gas flows through all three tubes.The inner tube is the injector and contains the sample aerosol in a stream of argon that delivers the sample to the plasma.Concentric to this tube is another tube of argon. This is the auxiliary gas that forms the plasma.The outer argon tube is a cooling layer to prevent the torch from melting.The far end of the torch has a copper induction coil (or ‘load coil’) surrounding it that connects to a radio frequency (RF) generator.How the ICP Torch Ionizes a Sample.The RF generator supplies power to the load coil, creating a high-frequency alternating current. This, in turn, induces a time-varying electromagnetic field in the torch. As a result, with argon gas flowing through the torch, the application of a high-voltage discharge (called a Tesla spark) ionizes a fraction of the argon atoms generating ions and electrons.The electromagnetic field in the torch then acts on the ions and electrons. As a result, they accelerate and collide with other argon atoms. If these collisions impart enough energy, additional atoms ionize creating electrons and ions that propagate the cascade.As a result, the movement of electrons and ions in the torch generates tremendous heat. The result is an ICP, which reaches a temperature of up to 10,000 Kelvin (hotter than the surface of the sun).What Is PFA Inert?PFA is frequently employed as an inert substance in sample equipment on geochemical or environmental analytical chemistry field sites to assist in avoiding trace amounts of metallic ion contamination.Features of Torch Fixed 1.5mm Injector 1 Pin 450-01.Single Piece TorchSingle-piece inductively coupled plasma (ICP) torches have narrow bore injectors (1.0 mm or 1.5 mm) designed to improve plasma stability and reduce plasma loading when used with organic solvents. They are the least expensive type of torch to buy initially, but they are also the least versatile and must be replaced entirely if any component is damaged. Single-piece torches can also be expensive consumables that require regular maintenance and replacement, especially when used with aggressive sample matrices like hydrofluoric acid, organic solvents, and high total dissolved solids.Do you have questions?
