It may not be the most glamourous of processes, but filtration, purification and separation are essential aspects of sample preparation, vital to almost all researchers’ day-to-day work. One company, ...

Air filtration, as we all know, is the process of separating dispersed particles from air by means of porous media. Filter fibers are expected to separate and retain particles on or within the filter ...

Preparing samples by clarification is an essential step prior to nearly all analytical techniques, such as high pressure liquid chromatography (HPLC). This filtration step to eliminate particles is ...

There are three distinct steps when preparing a dry sample of a soluble salt from an insoluble oxide or carbonate and dilute acid: filtration, evaporation, crystallisation. It's important to ...

Pew Research Center designed this study to assess the current state of online survey sampling methods – both probability-based and opt-in – and determine their accuracy on general population estimates ...
