This application gives the use of potentiometric sensor in the determination of the titer value without changing the method. The use of heater DH100 for complete removal of CO2 after the first equivalence point leads to very high precision results. Depending on instrument type, manual operation ...
p-value > 0.05), the datapoint was included in the toughness regime, and the Fice value of the next shortest length of ice was considered. This procedure was repeated until the Fice value from the longest piece of ice in the strength-controlled regime was statistically different (p...
In this work, high performance liquid chromatography has therefore been used as a complementary tool with differential scanning calorimetry to determine the appropriate liquidus point for various mole fractions of vitamin C–acetaminophen. Because a classical thermodynamic approach is not sufficient for ...
