DescriptionTorch Fixed Plasma 2.0mm Injector 1 pin 450-20Part Number: PG450-20Cross Reference(s) Thermo: 3600971Instrument Compatibility: Thermo X-SeriesDetail: Quartz, Plasma Torch, fixed 2.0mm ID injector, single locator pin.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.Features of Torch Fixed Plasma 2.0mm Injector 1 pin 450-20.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?
