    2019-11-27 · Abstract. A sensitive and specific heating block method coupled with ultra-HPLC (u-HPLC) was developed for the analysis of capsaicin in Gochujang and validated by comparing with a conventional HPLC (AOAC Method 995.03). The method validation parameters yielded good results, including linearity, precision, accuracy, and recovery.

  • Liquid Level Measurement Using the Bubbler Method

    2013-2-13 · molecules of similar size and character are mixed together in the liquid phase. In Aspen Plus, ideal behavior is modeled using the IDEAL property method. This method sets the activity coefficient for the liquid phase to 1, the EOS to the ideal gas law, and estimates the molar volume of liquids using the Rackett model.
