The goal of scientists is to obtain measured values that are both accurate and precise. Suppose, for example, that the mass of a sample of gold was measured on one balance and found to be 1.896 g. On a different balance, the same sample was found to have a mass of 1.125 g.
Trained laboratory personnel must understand how chemical laboratory facilities operate. Given the chance, they should provide input to the laboratory designers to ensure that the facilities meet the needs of the functions of the laboratory.
Chapter 8: Sampling, Standardization, and Calibration. A chemical analysis uses only a small fraction of the available sample, the process of sampling is a very important operation. Knowing how much sample to collect and how to further subdivide the collected sample to obtain a laboratory sample is vital in the analytical process.
26 Ιαν 2024 · National reference laboratories, also known as the central level, oversee the overall management of the laboratory network and provide a range of routine and specialized laboratory testing, introducing and phasing new diagnostic tests. They also perform the following functions:
24 Απρ 2023 · A central lab is an essential partner in the success of clinical trials. From building the initial specimen collection kits all the way through safety and specialty testing of study participant samples, central labs enable new investigational products to be evaluated for safety and efficacy.
22 Σεπ 2023 · The applications of chemicals as well as laboratory equipment can be known from chemistry laboratories. Students, researchers, and professionals learn about chemical reactions, measuring reactants, performing experiments, and analyzing data.
