JIEBO Knowledge Base
Practical guides to optical emission spectrometry, X-ray fluorescence, laser-induced breakdown spectroscopy and combustion-based elemental analysis. Written by JIEBO application engineers for foundry, metallurgy, aerospace and recycling customers.
What is an Optical Emission Spectrometer (OES)?
Definition, working principle, applications, OES vs XRF vs ICP comparison, how to choose.
OES vs XRF vs LIBS: Which Technique Fits Your Application?
Head-to-head technique comparison with a decision tree — destructive vs non-destructive, light elements, regulation, speed.
How to Choose an Optical Emission Spectrometer
Four-question decision guide (matrices, detection limit, throughput, environment) mapped to JIEBO's five OES models.
Carbon Analysis in Cast Iron: OES vs Combustion C/S Analyzer
Why foundries run both techniques, with grade-by-grade carbon-range reference and instrument pairing recommendations.
OES Sample Preparation: How to Get Accurate Readings
Practical checklist: surface, argon, electrodes, sample stand. Diagnostic table for out-of-tolerance readings — 80 % of OES drift is sample-prep, not the instrument.
