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. However, because some labs have certain restrictions regarding cryogenic fluids or are concerned with the price of helium, the need for additional flavors of VHA has become more salient. In this presentation we’ll look at two methods utilizing alternative columns, carrier gases, and starting oven temperatures and compare data from those methods to “traditional” VHA.
