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.

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.
2-Slot Torch
A two-slot ICP torch is a component used in ICP-OES (Optical Emission Spectroscopy) systems. Therefore, it’s designed with two slots to accommodate different viewing configurations for the plasma. This is where the sample is ionized and emits light at characteristic wavelengths that can be measured.
The two-slot torch typically refers to a torch with a slot for radial viewing, which can be part of a dual-view system allowing both radial and axial viewing. This design helps in handling tough samples with less cleaning and a longer torch lifetime. Some two-slot torches are also semi- or fully demountable, which can reduce operating costs by enabling parts like the outer tube or the injector to be replaced separately.
- Axially viewed systems, where the torch is oriented horizontally and viewed end-on, offering greater sensitivity.
- Radially viewed systems, where the torch is vertical and viewed from the side. This is the preference for complex high matrix samples and volatile organic solvents because the vertical orientation reduces matrix or carbon buildup on the torch.
