D-Torch for HJY Radial
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. It is also beneficial for Si determinations, where quartz outer tubes often produce high background signals. In general the ceramic outer tube has a much longer lifetime, greatly reducing interruptions and downtime due to torch failure.
What Makes the D-Torch for HJY 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 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.
