Tetraethyl orthosilicate or Tetraethoxysilane or TEOS (Si(OC2H5)4)
Standard range 30ppm
TLV level (TLV-TWA)
Relative density (compared to air):
- TEOS is mainly used as a crosslinking agent in silicone polymers and as a precursor to silicon dioxide in the semiconductor industry
- TEOS is also used as the silica source for synthesis of some zeolites
- It is also used in the coatings for carpets
Are you looking for a gas detection solution for Tetraethyl orthosilicate?
New Cosmos offers a variety of Tetraethyl orthosilicate gas detectors such as the SH-4001WAD/TEOS detector which does not respond to IPA. Very often IPA is a source of false alarms on TEOS detectors. New Cosmos-BIE has developed a special detector which can see the difference between TEOS and IPA. False alarmas in you clean room belong to the past when using this detector.
