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 NU Plasma Torch NU-102O.
Standard ICP Torch
Every mass spectrometer has many essential parts, but the heart of ICP analysis is the plasma torch that ionizes sample materials. The large 2.5mm injector on the standard torch gives maximum robustness and the lowest matrix interferences for the best plasma stability. The ICP torch’s purpose is to form, shape, and sustain an argon plasma that atomizes and ionizes a sample aerosol. The plasma is then fed into a mass spectrometer (MS) to detect multiple elements simultaneously. ICP-MS is a type of atomic mass spectroscopy that can quantitatively, semi-quantitatively, or qualitatively determine one or more elements in a sample. It can also measure organic solvents, detect nanoparticles, and analyze solid materials and gases.
Single Piece Torch
Single-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.
