Ergonomic and efficient filtration for food analytics
In food analytics, clarification by membrane filtration is often an important step in sample preparation for processes like HPLC. Designed for parallel processing of up to eight samples, the Claristep filtration system was examined in this application note to determine its suitability for the filtration of food samples.
HPLC: Improved sample preparation for high-sensitivity analysis
High-performance liquid chromatography (HPLC) is a powerful analytical tool used for the separation, identification and quantification of individual compounds within a sample.
Using high-pressure systems and the latest column chemistry, this technique makes separations faster, reduces solvent consumption and increases resolution and sensitivity of results. Effective sample and standards preparation are important steps in order to achieve reproducible and specific results.
In this application-based eBook, we look at effective HPLC sample preparation and cover:
- Preparation of solvents
- Preparation of standards
- Filtration systems
Impact of the Claristep Filtration System on Recovery and Adsorption of Various Therapeutic Proteins at Low Sample Volumes
Biopharmaceutical samples often contain insoluble particles like cell debris or protein aggregates from their biotechnological production processes. These particles can damage analytical instruments, e.g. by blocking capillaries of auto-samplers of analytical devices or chromatography columns, and are typically removed by centrifugation or filtration. Whereas centrifugation can only separate based on differences in density, the latter method is often preferable because an absolute particle removal can be achieved.
