Torch – Fixed – 2.0mm Injector – 1 Pin – 450-04

DescriptionTorch – Fixed – 2.0mm Injector – 1 Pin – 450-04Part Number: PG450-04Cross Reference(s) Glass Expansion: 30-807-0532 Thermo: 3601147Instrument Compatibility: Thermo VG PlasmaQuad 1-3, PQ Excell Thermo VG  Axiom Thermo X-Series and X-Series II ICP-MSTorch Detail:  Quartz, Fixed, 2.0mm ID injector, single locator pin, 12/5 (S13) BallWhat 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.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 the ICP Torch – Fixed – 2.0mm Injector – 1 PinSingle 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?
