Torch Detail:
This is an exact match OEM replacement quartz torch suitable for the Agilent 7500 HMI (High Matrix Introduction) ICP-MS instrument and backwards compatible with all previous Agilent 7500 instruments. This torch has a fixed 2.5mm ID quartz injector and dual alignment pins.
Precision Glassblowing also offers previous version 2.5 mm ID fixed injector (Precision Glassblowing PG900-06 and 1.5mm ID fixed injector PG900-07 torches for those not running HMI instruments. Also offered are demountable torches with both quartz and alumina injectors.
Features of the ICP Torch OEM# G3270-80043?
Standard ICP Torch
Every mass spectrometer has many essential parts, but the heart of ICP analysis is the plasma torch that ionizes sample materials. The large 2.5mm injector on the standard torch gives maximum robustness and the lowest matrix interferences for the best plasma stability. The ICP torch’s purpose is to form, shape, and sustain an argon plasma that atomizes and ionizes a sample aerosol. The plasma is then fed into a mass spectrometer (MS) to detect multiple elements simultaneously. ICP-MS is a type of atomic mass spectroscopy that can quantitatively, semi-quantitatively, or qualitatively determine one or more elements in a sample. It can also measure organic solvents, detect nanoparticles, and analyze solid materials and gases.
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.
