A substantial portion of the temperature shift of the hydroxyl proton is found to be due to density variation. An essentially linear change of the hydroxyl shift with density at five constant temperatures can be described by an empirical equation valid only for liquid ethanol relating the relative...

For gel-type hand sanitisers, their specific gravity at 25 °C (weight/mL) was initially determined using a density meter (Mettler Toledo, Greifensee, Switzerland). Based on the specific gravity, an amount equivalent to 0.2 mL of a gel sample was weighed in a 20 mL volumetric flask. Next...

This method is simple and practical, but only the density information of the liquid can be obtained. The monitoring technology and indicators of EPP in the literature are listed in Table 5. At present, near-infrared spectroscopy (NIR) is widely used due to its simple sample preprocessing, ...

They were group-housed (4/cage) and allowed to acclimatize to the colony room for at least 1 week in a temperature- and humidity-controlled AAALAC- approved facility. Animals were maintained on a 12 h light/ dark cycle with lights off at 0900 h and had ad libitum access to food and ...
