Background
Propellant stability screening in the field
• Real-time, non-destructive operation• Operated by field personnel• Eleven instruments• Applicable to eleven propellant types:
First calibration model met initial criterion with SECV ≤ 0.07

Calibration Transfer
Calibration model from spectrometer 1 electronically transferred to spectrometer 2
Spectra on spectrometer 1 nearly indistinguishable from
spectra of same sample on spectrometer 2
