Carbon and Silicon Analysis
The world’s first handheld analyzer to deliver carbon content just got better

Why the CSi?
Many operators own one or more XRFs for PMI/NDT. It’s their preferred tool for high temp alloys, and for elements contributing to carbon equivalents (CE), residuals, and stainless steel grades: V, Mn, Cr, Ni, Cu, Nb, Mo. However, XRF does not measure carbon and therefore no carbon equivalents, no separation of L- and H-grade stainless, nor can you use the more forgiving low RE formula (Ni + Cu) < 0.15%. The CSi is the perfect tool for operators who own XRF and need the occasional carbon measurement. It delivers fast, reliable carbon results to complement XRF tests, at a lower cost than the full LIBS system for carbon plus alloys. And SciAps cloud-driven data merging and report generation bring it all together in one report.
The CSi shows multiple carbon and silicon measurements, and the average. Meets multi-test averaging protocols required by some refineries and pipeline operators. |
SciAps breakthrough LIBS technology is now widely accepted for carbon testing.
It’s included in API 578 2nd Edition, it’s accepted at most every major refinery, and in use worldwide by fabricators, pipeline owner/operators, power plants and other users of carbon steels and L- and H-grade stainless.
Ultra compact: At 3.5 lbs. (1.6 kg),
The CSi rivals the size and weight of most handheld XRF units. It’s the world’s smallest, lightest weight, sleekest analyzer for carbon analysis in alloys.
Cloud-based integration of XRF and CSi data
Two analyzers means twice the reporting hassle, right? No. SciAps offers a cloud-based data merge and reporting tool so you can quickly merge CSi and XRF data to produce reports combining carbon and silicon from the LIBS with metals analysis from the XRF. Are you using a different XRF brand? No problem – ask your supplier for the data structure of their data export and we’ll incorporate it into our SciAps Cloud package. The data structure generally follows an industry standard and doesn’t involve proprietary software.
