Learning or mastering new skills as an adult can feel daunting. These three tips will help.
With modern chromatography modelling software, is it time to hang up our laboratory coats? Is resistance to software solving separations futile?
Are we ready to let software and instruments take over the art of separations?
When selecting new candidates for multifaceted analytical separation science jobs, we rarely find an exact match. So what should we be looking for in job candidates?
Is there a secret formula to getting hired into a pharmaceutical analytical chemistry group? What skills are prized above all others?
