ICP Plasma "torch". The ICP-AES is composed of two parts: the ICP and the optical spectrometer. The ICP torch consists of 3 concentric quartz glass tubes. [2] The output or "work" coil of the radio frequency (RF) generator surrounds part of this quartz torch. Argon gas is typically used to create the plasma.
Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry that uses an inductively coupled plasma to ionize the sample. It atomizes the sample and creates atomic and small polyatomic ions, which are then detected.
The collision reaction cell, also known by the trade name "dynamic reaction cell" (DRC), was introduced by Perkin-Elmer on their Elan DRC (followed by Elan DRC II and Elan DRC-e) instrument. The dynamic reaction cell is a chamber placed before the traditional quadrupole chamber of an ICP-MS device, for eliminating isobaric interferences.
ICP discharges are of relatively high electron density, on the order of 10 15 cm −3 [citation needed]. As a result, ICP discharges have wide applications wherever a high-density plasma (HDP) is needed. ICP-AES/ICP-OES, a type of atomic emission spectroscopy. ICP-MS, a type of mass spectrometry. ICP-RIE, a type of reactive-ion etching.
The development of analytical nebulizers since the introduction of the ICP / ICP-MS is seen below: [6] 1970s Adjustable Cross flow (US patent #4,344,574) [7] 1974 Meinhard Concentric 1978 V-groove (by Suddendorf and Boyer) (US Patent #4,206,160) [8] 1980 Pillar and Post (by Garbarino and Taylor) 1983 GMK Nebulizer: Glass Babington V-groove

PerkinElmer, Inc., previously styled Perkin-Elmer, is an American global corporation that was founded in 1937 and originally focused on precision optics. Over the years it went into and out of several different businesses via acquisitions and divestitures; these included defense products, semiconductors, computer systems, and others.
Peroxide fusion is used to prepare samples for inductively coupled plasma (ICP), atomic absorption (AA) analysis and wet chemistry. Sodium peroxide (Na 2 O 2 ) is used to oxidize the sample that becomes soluble in a diluted acid solution.
