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.
Metrological traceability: central concept of metrology and requirement of accreditation standards worldwide
Metrological traceability is necessary for consistent, comparable and valid measurement values. As a fundamental concept of modern-day metrology, it allows measurement results to be internationally recognized and is required by norms and accreditation standards all over the world. The ...
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) ...
The new definition of the SI base unit of mass and its significance to the weighing world
For about 200 years, any mass given in kilograms, grams and micrograms referred to a defined artifact accessible in only a single location on earth. A small metal cylinder had represented one kilogram since the metric system was introduced in France. Its successor became world famous as the ...
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 ...
ICH Linearity Studies using Automated Standard Preparation and UHPLC
According to the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH), it is necessary to test analytical methods for their linearity as part of a method validation study. The typical process for this is to prepare standards ...
GWP® (Good Weighing Practice™) Life Cycle Management – 5 steps that support the Lean principles perfectly
A Lean Laboratory focuses on testing products and materials to deliver results in the most efficient way in terms of cost and speed. An accurate result for the customer is a pre-requisite. However, to guarantee accuracy of a weighing device over time requires using the correct balance as well as ...
Accreditation requirements for laboratories
Several key international standards for laboratories are currently being revised, of which DIN EN ISO/IEC 17025  is probably the most important. This will involve a number of changes for laboratories. Independently of revisions to standards, however, accreditation bodies are also ...
Gravimetric solutions for pipette calibration
Regular testing is essential to ensure that pipettes work accurately and precisely. However, measuring the volume of liquids is subject to inherent risks, particularly when the volume is small. Gravimetric solutions for testing and calibrating pipettes offer precise and regulatory compliant ...
