Fremgangsmåte og apparat for direkte bestemmelse av oktantall |
| 摘要 |
The octane number of a product is determined from its near infrared (NIR) absorption spectrum in the wave number spectral range from 6667 to 3840cm<-><1>. A number (n) of frequencies are selected within this range and the (n) absorbance values are correlated with the octane number by means of multivariate regression analysis. |
