Mobile Optical Emission Spectrometers

Spark mobile optical emission spectrometers (OES) excel at providing full chemistry of critical alloy elements at low detection limits that handheld X-ray and LIBS analyzers can’t: carbon, phosphorus, sulfur, boron, arsenic and tin in low alloy and stainless steels, and nitrogen in duplex steels.

That’s why spark OES is the most trusted and widely used method for creation and verification of MTR’s (mill testing reports) in the world. Our mobile and portable spectrometers also meet the world’s most stringent PMI metallurgical alloy chemistry testing requirements including API 5L testing, API RP578, ASME section IX B& PV, and ISO 17025.
