Questions answered in these manuals
What ASTM method is used for analyzing aromatics in gasoline?
The document uses American Society of Testing and Materials Method D5769.
Does the extended linearity source improve calibration?
Yes, it provides greater linear dynamic range, resulting in a coefficient of determination (r²) of 0.997 for toluene compared to 0.911 for the standard source.
What is the recommended split ratio for the GC injection port?
The recommended split ratio is 1100 to 1.
