The analysis of residual solvents or generally, volatile organic substances using static headspace gas chromatography, is often accompanied by matrix effects. The standard addition method (SAM) is the calibration method of choice for circumvention of

Recently, the European Medicines Agency (EMA) and the U.S. Food and Drug Administration (FDA) had reported on "unexpected" impurities in a couple of sartans, ranitidine, and metformin. These events led to a lot of discussion with regard to the risk a

Enzyme immobilization into solid mesoporous inorganic supports is a promising strategy to enable their use in continuous-flow fixed-bed reactors. In this study, the formation of cross-linked enzyme aggregates (CLEAs) of glucose oxidase (GOx) in the p

Doped glasses are usually manufactured by melting of silica. As the melting point of silica is 2100 °C, most of the suitable dopants evaporate. Hence, alternative processes for the fabrication of glasses are needed. Sintering of nano-sized silica po
