Detection and identification of vitamin D metabolites in plant sources
A vitamin is defined as an organic molecule essential for health. Indeed, vitamin D has been associated with bone health and with immune-related effects, however a vitamin D deficiency has been associated with chronic diseases and mortality .
A new General Chapter addresses balances for analytical purposes
Weighing is one of the key activities carried out in every quality control (QC) laboratory. Usually it is one of the first steps in a whole analysis chain, e.g. when a sample or a standard is prepared for subsequent dilution and HPLC or qNMR analysis.
Requirements for smart laboratory instruments and interconnected systems in the modular lab of the future
Laboratories tend to be central hubs for chemical, biotechnological, pharmaceutical or foodstuff production. They play a key role in research and development, chemical analysis, quality assurance, maintenance and process control.
Minimum Weight and Routine Testing According General Chapters 41 and 1251
Weighing is one of the key activities carried out in every QC laboratory. Usually, it is one of the first parts of a whole analysis chain. As any weighing errors have the potential to propagate through the whole analysis and deliver an inaccurate final result, the United States Pharmacopeia (USP) ...
Smart sample preparation improves selectivity of analytical procedures for biopharmaceuticals and other drug products
Impurity testing is an essential part of pharmaceutical quality control because toxicity and content of impurities contained in drug products can impair patient safety. This requires suitable, validated analytical methods.
First-Defect-Stop helps to improve quality through sustainable and reliable processes in weighing
The management concept “Lean Laboratory” is increasingly being implemented in the laboratory environment, with the aim of optimizing efficiency. An essential approach here is the “First-Defect-Stop”, which is based on the Jidoka principle and refers to the earliest possible identification of ...
Lean methods come to the lab…at last!
Is “lean lab“ just a management trend du jour or something which you need to carefully consider? The successful introduction of lean manufacturing into industrial production was completed years ago and is now an indispensable part of today’s highly competitive markets.
Where does manual sample preparation stand?
The pressure is on to do more with less. Whether this applies to increased workload with lower headcount or more analytical tests with less milligrams of sample, how can today’s pharmaceutical and biopharmaceutical companies make ends meet?
Automated MOSH/MOAH determination with the aid of coupled LC-GC
Once only of academic interest, the combination of liquid chromatographic separation with subsequent separation in the gas-phase is proving to be suitable for routine use. In routine laboratory work, the method continues to present a major challenge, above all with regard to precision, ...
