Detail
The D-Torch is a revolutionary new demountable torch design. It provides the benefits of a fully demountable torch at a significantly lower cost. Interchangeable outer tubes made of quartz or ceramic are available. The ceramic outer tube is of particular benefit for the analysis of wear metals in engine oils, where quartz outer tubes often suffer from short lifetime.
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.
What are the Features of the Torch?
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.
Demountable Torch
The D-Torch is a robust and higher-performing alternative to both a single-piece and a semi-demountable quartz torch. The demountable design offers several benefits, including ease of maintenance, flexibility in configuration, and the ability to customize the torch setup for specific analytical requirements. Additionally, it allows for thorough cleaning and removal of any sample residues or contaminants that may accumulate during analysis.
