Quantification and Identification of NOx Reduction Agent AdBlue (AUS32) by ATR-FTIR
Quantification and Identification of NOx Reduction Agent AdBlue (AUS32) by ATR-FTIRGlobal fuel standards require analysis to determine identity, quality, and chemical characteristics of AdBlue. A Cary 630 FTIR equipped with the single reflection diamond ATR module was used in identifying commercial AdBlue, as specified in the ISO 22241-2 standard. The study was extended to quantify urea and provided an easier and more economical alternative to ISO 22241-2 methods for routine quantification of urea content in AdBlue.
