Torch Detail:
This is an exact match OEM replacement quartz torch for PerkinElmer Optima 3X00 Dual View (DV) series ICP-OES instruments.
This torch has a single viewing 1-slot, but is also available in a 2-slot torch PG310-12 and 3-slot torch PG310-14/3SL
The torch does not include an injector or injector supports. Precision Glassblowing offers plastic injector support adapters and injectors of various sizes in both quartz and alumina.
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.

Single-Slot Torch
A single-slot ICP torch is a standard torch for aqueous solutions in ICP-OES (optical emission spectrometry) instruments. ICP-OES is a technique that uses plasma and a spectrometer to determine the composition of elements in samples, usually dissolved in water.
Single-slot torches are made of one-piece quartz tubing for plasma and auxiliary gas flow. They can be demountable and require regular maintenance and replacement, especially when working with aggressive samples like hydrofluoric acid, organic solvents, or samples with high total dissolved solids.
