DropSens interdigitated electrodes (IDEs) are composed of two interdigitated electrodes with two connection tracks, on a glass substrate. These IDEs offer several advantages, such as working with low volumes of sample and avoiding tedious polishing of solid electrodes. DropSens InterDigitated Gold Electrodes (IDEs) came up with a new gas sensors...Read More
In this Metrohm Application Note, it is shown how the combination of the Autolab PGSTAT204 with the 1 L corrosion cell and the NOVA software facilitates electrochemical impedance spectroscopy (EIS) on coated aluminum samples. EIS provides valuable conclusions concerning the coating quality and thus the corrosion resistance. The electrochemical impedance...Read More
Meeting stringent standards for food production or quality control is heavily dependent on reproducible and representative sample preparation. Food products are available in a great variety of forms and consistencies and are usually inhomogeneous. From detecting hazardous substances to finding nutritional values, homogeneous and representative samples are required to obtain...Read More
Simpler sample preparation. Faster analysis. Citirc acid is regularly added to carbonated beverages as it acts as a natural preservative while also improving taste. Of course, it is important to have enough citric acid to prolong shelf life and taste, while avoiding adding too much. Too much of anything is...Read More
Monitoring quality from the raw material to the final product is a vital requirement when processing juices and fruits. Spoilage, additives and ingredients are analysed and the quality of the product is monitored. Quality control in the fruit and juice industry is performed in two main areas: Spoilage control and...Read More
High standards require the most accurate analysis. That’s where DIA stands apart from other techniques! Higher resolution, better sensitivity, and excellent reproducibility: this is how Dynamic Image Analysis (DIA) improves the characterisation of powders and granulates in both quality control and R&D. This white paper outlines how particle size distribution...Read More
The purity of a solvent (dichloromethane/methylene chloride) is monitored by NIR spectroscopy along with two of the major impurities (methanol and water). Recovering solvents The solvents that are used in manufacturing processes are often not disposed of or incinerated, but instead recovered and purified, as this saves considerable costs. Distillation...Read More
Sometimes size does matter. Due to matrix complications, detection limit requirements and standard methods, pulsed ammperometric detectors, PADs, are common feature of ion chromatography in the pharmaceutical laboratory. A key benefit of the PAD is its selective nature. Along with the expected chromatography variations in columns and mobile phases, the...Read More
Copper online analyser installed. Tony Luu, Product support specialist, conducting the training for the operators. Metrohm Australia recently installed the ICON analyser to monitor the copper concentration in water supply. Copper-silver ionisation Copper-silver ionisation disperses positively charged copper and silver ions into the water system. The ions bond electrostatically with...Read More
Improve the analytical possibilities of your research laboratory. Chromatography analysis in the health field has been synonymous with HPLC instrumentation. While HPLC is the most common chromatography technique in pathology and health research laboratories, Ion Chromatography, as a sub-section of liquid chromatography is a very important technique as well. The...Read More
