OMNIS is the ideal system for quick and accurate determination of aluminum in aluminum chloride using complexometric back titration with an ion-selective copper electrode (Cu-ISE). Copper sulfate is used as the titrant.Read More
Particle characterisation by Dynamic Image Analysis (DIA) has become increasingly popular in recent years. This technique delivers very accurate particle size distributions in a very short time, is virtually maintenance-free and, unlike other methods like sieve analysis or laser diffraction, provides particle shape information. The CAMSIZER X2 is the latest...Read More
Detection techniques for Ion Chromatography – UV/Vis Analysing metal species or low-level nutrients in difficult matrices in environmental samples can cause headaches. With ion chromatography for separation and UV/Vis detectors, many of these headaches can be solved. Why IC and UV/Vis work Wide choice of separation columns and mobile phases...Read More
Professionals with years of practical experience write them, they have been used in teaching for a long time, and they are free: Metrohm Monographs The Metrohm monographs are a great tool for anyone who wants to teach themselves or students the basics of important analytical methods such as titration, KF...Read More
Inside the semiconductor fabrication facility, cleanliness is crucial, considering the scale of the working surfaces (nanometers). Contaminants of all types can result in defects, leading manufacturers to adopt ever stricter production control procedures. A single fabrication plant can use up to 15 million liters of ultrapure water every day. Even...Read More
Multi-species determination for fertilizer In close cooperation with Metrohm a Belgian company has developed an automated Wetchem system for the analysis of fertilizer samples. The system allows multi-species determination (about 10 different species) and also carries out the complete sample preparation procedure, which is particularly worth mentioning. Sample preparation for...Read More
Healthy fish require monitoring Adherence to strict environmental and health standards is important as a food producer. Animal health, hygiene, and especially water use are important factors to con sider in aquaculture. Disease and sickness can spread easily between the animals, and due to the nature of these floating aquatic...Read More
The sodium content of food and beverages is usually determined indirectly through a precipitation reaction with silver nitrate. This approach assumes that the chloride ions are present in a molar ratio of 1:1 with the sodium ions, which is not always the case. On the other hand, established methods for...Read More
Spectroelectrochemical measurements Combine electrochemistry and spectroscopy in one measurement with SPELEC. The SPELEC instrument is an integrated solution consisting of a bipotentiostat/ galvanostat combined with a spectrometer and a light source. It is available in two detection range versions (200–900 nm and 350–1050 nm). Spectroelectrochemistry is a useful technique used...Read More
Environmental analysis is a highly competitive market. Saving time and money while maintaining result quality is key to a competitive edge. Increasing environmental analysis productivity The ability to avoid sample preparation and expensive consumable parts has long been the desire of environmental laboratories. Sample preparation takes time and time equates...Read More
The complete homogenisation of fibrous food samples is a difficult task as fibres can pass the apertures of the bottom sieve in vertical orientation. A good tool for fibrous food samples: Retsch V rotor The use of the Retsch V rotor with the SM 300 significantly improves the homogenisation of fibrous materials....Read More
