Pharmaceutical analysis is traditionally defined as analytical chemistry dealing with drugs both as bulk drug substances and as pharmaceutical products (formulations). However, in academia, as well as in the pharmaceutical industry, other branches of analytical chemistry are also involved, viz. bioanalytical chemistry, drug metabolism studies, and analytical biotechnology. The cover story of this month titled: “Common error minimization tips for Pharmaceutical Analysis” mainly for solving numerous uncertainties usually encountered during pharmaceutical analysis. The analyst has no control over random errors, but systemic errors can be minimized by using certain error minimization steps. The edition has a featured article entitled “Using powder flow measurements to predict feeder performance" contributed by Tim Freeman, Managing Director, Freeman Technology, and Ralf Weinekötter, Managing Director, Gericke AG. The article predicts the performance of processing equipment from powder properties measurements, which is an essential goal for the powder processing industries.Read more
