ISO/IEC 17025:2017 - Shimadzu

ISO/IEC 17025/2017 regulates the complete operational processes in a testing or calibration laboratory. Chapter 7: "Process requirements" is particularly relevant for the specific procedure in the laboratory. Here, processes from sampling to report generation for the customer are defined and described in detail.

RETROSYNTHETIC ANALYSIS

Retrosynthetic Analysis and Synthetic Planning Definitions 2 Retrosynthetic analysis is a technique for planning a synthesis, especially of complex organic molecules, whereby the complex target molecule (TM) is reduced into a sequence of progressively simpler structures (retrons) along a pathway which ultimately leads to the identification

Analysis of Microplastics using FTIR Imaging

One major challenge in the microplastic analysis of environmental samples is the removal of organic/biological matter. Due to the hydrophobic nature of many plastics, organic matter will aggregate onto its surfaces and must be removed before the microplastic can be characterized spectroscopically. Oxidation by H 2 O was selected as the
