Physical stability of agrochemical formulations and observation of eutectics
25 Mar 2020Physical stability of formulations is an important parameter during formulation development, especially when testing multiple phase systems (suspensions or emulsions). In this application note, Dr. Martin Viertelhaus from BASF SE, explains the essentials of physical stability of formulations, covering topics such as stability testing, observation of eutectics and how the Crystalline instrument can be used to obtain this information.

X-ray CrystallographyX-ray crystallography is an analytical technique used to determine the arrangement of atoms in a crystal. Monochromatic x-rays are produced from a synchrotron or x-ray generator. An x-ray crystallography system uses a detector to measure the x-ray diffraction from the crystal. The information is used to generate a 3D image of the crystal.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Protein CrystallographyProtein crystallization is the process of crystallizing purified proteins for 3D structure analysis by x-ray crystallography. The main methods of protein crystallization include sitting drop, hanging drop and microbatch. It is important to control parameters such as pH, temperature and concentration. Following crystallization, detectors and software are used for data collection and analysis.Biopharmaceutical AdvancesBiopharmaceutical advances follow the development of pharmaceuticals derived from biotechnology, also known as biotechnology medicines. Biopharmaceuticals may be produced from cell lines, plants, or microbial cells. Important considerations of biopharmaceutical use include application, cost, production process and purification.AgrosciencesCrystallizationCrystallographyProtein Stability
