What is the Role of the ICP Torch?
A plasma is an ionized gas, consisting of positively charged ions and free (unbound) electrons. The role of the plasma (ICP) in ICP-MS is to ionize the sample. In contrast to so-called ‘soft’ ionization sources in other forms of mass spectrometry, the ICP is a ‘hard’ ionization technique because it completely atomizes most molecules in the sample.
ICP-MS instruments use an argon plasma, although helium plasma is also an option. Although there are several advantages to using helium, argon is the gas of choice since the cost of helium is prohibitive.

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.
