Most buyers reach us mid-evaluation. These pages set out where OrionIR® is the right answer and, just as usefully, where another method is.
OrionIR® vs ReactIR
In-situ FTIR from a benchtop console versus a palm-sized inline module.
OrionIR® vs ATR probes
Probe-surface sensing versus transmission through the stream.
FTIR vs Raman
Which technique sees which bonds, and where fluorescence gets in the way.
FTIR vs NIR
Fundamental versus overtone absorption, and what that means for calibration effort.
Inline vs offline analysis
What the 2–24 hour sampling delay actually costs.
Calorimetry vs in-situ IR
Heat flow versus composition — complementary, not interchangeable.
