Quality control in the pharmaceutical industry is indispensable. As a selected test method, titration is described in many pharmacopeias due to its ease of performance and accuracy, as for example in the United States Pharmacopeia-National Formulary (USP-NF) General Chapter <541>. Here, potentiometric titration and other detection principles in an automated titration procedure exemplify a ...

Why Conduct Lyophilized Liposome Residual Moisture Analysis? Determining the residual moisture content of lyophilized liposomes is important for several reasons. ...
The IEA (International Energy Agency) expects demand for electric vehicle batteries to increase between four and a half and seven times by 2030 compared to 2023 [1]. The biggest part of the battery production cost is the materials, and cathode production is the most expensive part of the material costs [2]. A good quality control program for cathode production is important to avoid high scrap ...

Conductometric titration, also called conductivity titration, is an analytical method based on the change of conductivity while adding a titrant. The change of the conductivity of the solution is measured after each titrant addition. This is done with a conductivity sensor. Principles, advantages, and some examples of conductometric titration are given in this blog ...

It is suitable for the determination of all kinds of substances: chemicals, oils, pharmaceuticals and food, etc. At present, Karl Fischer titration has developed into a moisture analysis method widely used in the world. ...
In this white paper, two different methods for the analysis of dissolved oxygen, titration and direct measurement, are compared and contrasted to help analysts determine which method is more suitable for their specific applications. ...
Drink orange juice, it’s good for you because it contains vitamin C!» Most people have probably heard this or a similar command in their childhood. Vitamin C, also known as ascorbic acid or L-ascorbic acid, is an essential nutrient which humans cannot produce by themselves. We rely on external sources like fresh fruits and vegetables to obtain it. As vitamin C has antioxidant ...

Gravimetric analysis Gravimetric analysis is the basic method of chemical analysis in drug analysis and testing. ...
International Coffee Day is October 1st, not that many of us need a day to celebrate the drink we enjoy all year round. What makes a high quality cup of coffee? There are several factors at hand from the origin of the beans and the climate they grow in, to how the beans are processed, roasted, and packaged, and finally how the roasted beans are ground and brewed. In this blog post, I will discuss ...
Equipment: AutoKjeldahl Unit K-370 The AutoKjeldahl K-370 performs the distillation and titration steps for protein analysis fully automated. The Digestion Unit K-435 is used to digest the samples prior to distillation, and hazardous fumes of acidic nature are safely absorbed in the highly alkaline solution of the Scrubber Benefit / Conclusion: Time saving and ...

Removal of total cyanide was determined using the silver nitrate titration method. Regression analysis and optimization of the conditions were conducted using the Design-Expert software and response surface methodology (RSM). The actual cyanide removals and the removals predicted using RSM analysis were in close agreement, and the optimal ...
The biosorbents were characterized by zeta potential, infrared (IR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive spectroscopy and Boehm titration. The results of Boehm titration and IR analysis indicated the presence of basic functional groups, whereas those of SEM analysis indicated that the biosorbents ...
Both NO 2 and CO at 7:00–9:00 highly correlated with the O 3 in the following afternoon. Principal component analysis (PCA) and an analysis of non-methane hydrocarbons-to-NO 2 ratio suggest the NO 2 -limited O 3 formation in the BMR suburb. The PCA also suggests a negative response of wind speeds on the afternoon O 3 formation, whereas roles of ...
The tubers were immersed in solutions of cysteine hydrochloride, citric acid combined with ascorbic acid, ethylenediaminetetraacetic acid/EDTA and sodium metabisulfite. Analysis of pH, total titratable acidity, soluble solids, water activity at 5°C and moisture at 5°C and 10°C for until 96 hours of storage were carried out. ...
The Titration Excellence line combines application flexibility with most efficient operation in titration. ...
Everybody expects clean and safe tap water when turning on their taps. A water quality analysis center in Shanghi, China excels in its water testing and analysis with fully automatic potentiometric titration. ...
Using the methods described below calcium and magnesium will not interfere and can even be deter¬mined in the same analysis. IntroductionSeveral different titration methods are used to determine sulfate content: Titration with barium perchlo¬rate using thorin as indicator. Indication: DP5 Phototrode™ at 555 nm (colorimetric elec¬trode) ...
Introduction The biofuels industry is growing rapidly and so is the need for analysis to ensure quality product. The parameters for quality biodiesel require different types of instruments and measurement systems, such as gas chromatographs (GC), titrators, centrifuges, infrared spectrometers... ...
