ICP-MS
is an acronym for Inductively Coupled Plasma Mass Spectrometry. ICP-MS is a
mass spectrometry instrument that analyzes elements by ionizing them with
inductively coupled plasma. An inductively coupled plasma creates ions from
samples in gas clusters ionized by electromagnetic fields or through chemical
reactions using reagents. In ICP-MS, an example is atomized and ionized in a
plasma. Typically the plasma is an argon gas plasma, but helium or nitrogen
plasmas can be used.
In 1928 Sir J.J Thomson first discovered the particle nature of atoms through
his research of gases using electron beams, even though bits were already known
to be made of particles.
It wasn't until the 1940s, however, that Martin and Synge first used mass
spectrometry to analyze ions in gases through electron impact or chemical
ionization; Technical limitations at the time led many scientists to abandon
this method for gas analysis.
It wasn't until the 1960s that plasma sources became available. A plasma is a
gas with particles removed to offer ions, electrons, and neutrals, which can be
used for analyzing elements through ICP-MS.
Molecular biology lab services
Operations within molecular biology lab services, such as sequencing DNA and
RNA at the genetic level, demand quality results. ICP-MS can be used to analyze
a sample before sequences are performed to ensure accuracy.
Microbiology Tests-
ICP-MS is used to test for microbes within food and water samples. This testing
can reveal if there are any pathogens or bacterial contaminants in the sample,
as well as what types of bacteria are present. One example is checking for E.
coli by analyzing a stool sample with ICP-MS. This test can be helpful to
restaurants who want to check the safety of their food and hospitals checking
on patient safety.
Environmental Testing-
ICP-MS is used within environmental testing to find heavy metals in water
samples. This allows scientists and technicians working in environmental
departments and laboratories to know if a substance has hazardous levels of
heavy elements such as lead, mercury, and cadmium.
