This application note discusses a total workflow for the analysis of water and wastewater samples using the latest innovations in ICP-MS instrumentation which offers a comprehensive solution for effective and trouble-free analysis of samples containing high dissolved solids. The complete method quality control protocol was included in this study to ensure accuracy, precision, and reproducibility of an extended analysis consisting of 600 samples.
Oligonucleotide Analysis in Pharmaceutical Quality Control
January 14th 2025Melting point determination using ultraviolet-visible (UV-Vis) spectrophotometry can be used as a sequence-specific method for identifying therapeutic oligonucleotides in pharmaceutical quality control. This method offers a simple, highly selective approach to differentiate between isomers and ensure the integrity of oligonucleotide active pharmaceutical ingredients (APIs) and drug products.
The Optical Properties of Solid Samples
January 14th 2025Transmittance and reflectance measurements, which are useful for estimating the effects of various physical processes, can include thermal treatments, ionizing radiation exposure, optical exposure, and mechanical treatments—on both crystals and thin films.
