Space is the place…to experiment

Bugs in Space – ATCC® Microbes are Go! by Lauren Cracknell. Students taking part in the ISSET programme at King’s College, London, have designed and prepared ‘micro-gravity experiments’ using ATCC’s Microbes. The intrepid microbes were launched into space on-board the Falcon 9 rocket and rendezvoused with the International Space Station on 5 June. The aim of …

Nitrate in infants’ vegetable food

Nitrate is a natural contaminant present mainly in vegetables and drinking water although it is frequently added as a preservative in processed meat products. Plants utilise nitrogen from the environment as part of the nitrate cycle, for their metabolism and to produce protein. Any excess quantity of nitrate is stored mainly in green leaves.  In …

Are your assay values below specification?

“The result I’ve found for the assay value in my API or finished dosage form is below my specification. Is there a problem with my reference standard?” is a question often asked by users of pharmaceutical reference materials. Some may even assume that there has been some degradation with the reference material they have applied. …
