The importance of homogenisation for food testing

The importance of homogenisation for food testing

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...

Citric acid in beverages

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...

Monitor specific analytes in juices and fruits

Monitor specific analytes in juices and fruits

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...

High standards require the most accurate analysis

High standards require the most accurate analysis

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...

Monitoring the purity of recovered solvents with NIRS

Monitoring the purity of recovered solvents with NIRS

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...

Improved limits of detection with electrochemical detection

Improved limits of detection with electrochemical detection

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...

Cryomilling! Size reduction of your temperature sensitive samples with ease

Cryomilling! Size reduction of your temperature sensitive samples with ease. A solid sample material should always be sufficiently prepared by size reduction andhomogenization before it is subjected to chemical or physical analysis. Care should be taken that the analysis sample fully represents the original material and that the sample preparation...
