Abstract:
Verified Hydrocarbon Analysis (VHA, ASTM D8369) offers an alternative to traditional DHA that delivers better accuracy and precision - through vacuum ultraviolet (VUV) spectral verification and an automated analysis - in a fraction of the time. A recent study directly comparing VHA and DHA highlights the ease of use and superior results obtained from VHA. Additional comparisons were performed for each method using hydrogen carrier gas, demonstrating VHA’s analytical flexibility with spectrally verified results.
