WebJul 1, 1985 · The pH-stat could handle up to 20% oleic acid (more than 100,umol/min) with less than 2% deviation from theoretical, provided stirring in the titration vessel was sufficient. In activity measurements, rates did not usually exceed 20 ymol/min. WebWith the advent of rapid-responding pH and reference electrodes coupled to sensitive pH meters, these changes in H + ion concentration could be accurately measured. That measurement, which can be performed either directly or indirectly, forms the underlying principle upon which the electrometric methods for the assay of CA activity are built.

WebA method was described where the hydrolysis of triolein to fatty acids and glycerol by lipoprotein lipase (LpL) was continuously monitored by titration of the liberated protons in a pH-stat automatic titrator. The method gave results comparable to those obtained by a conventional assay, and was also found to be applicable to the study of crude ...
WebMar 5, 2024 · The degree of hydrolysis (DH) was determined by the pH-stat method, the hydrolysates profiles were analyzed by high-performance liquid chromatography (HPLC), the molecular weight distribution (MWD) was analyzed by gel filtration chromatogram (GFC), and content of SH/S-S and antioxidant activity of hydrolysates were evaluated. WebJun 10, 2015 · The alpha-stat hypothesis suggests we always interpret our blood gases as corrected to the same temperature (normal body temperature) irrespective of what the body temperature actually is. The pH-stat hypothesis instead recommends that we always correct the temperature to the core body temperature. Each approach has its merits and demerits.
Webstat, where pH is controlled by titrating with acidic and/ or basic solutions. Ionic equilibrium can be monitored continuously by measuring the solution pH.
