Why an Alumina Injector?
An alumina injector (aka, ceramic injector) is a component used in an inductively coupled plasma (ICP) optical emission spectrometer (OES) to deliver a sample aerosol into the plasma region.
Alumina injectors are made from alumina, a ceramic material primarily made of aluminum oxide. They are used when samples contain high levels of alkali metals, such as lithium-battery materials, or hydrofluoric (HF) acid digests. Alumina injectors are more resistant to these substances than quartz injectors, which free HF can degrade. Alumina injectors are also corrosion-resistant to all mineral acids, including aqua regia.
In addition, alumina injectors are available in different inner diameters, and the size you need depends on the type of sample you’re analyzing:
- 0.8 mm for 1.4 mm for analyzing organic solvents
- 1.8 mm for aqueous analysis
- 2.4 mm for samples with high total dissolved solids
