To manage the large sample loads that are typical of many environmental testing laboratories, ICP-OES users need instruments that deliver fast sample-to-sample analysis times, while generating consistently high-quality results. Agilent has developed the Advanced Dilution System (ADS 2) for Agilent ICP-OES (and ICP-MS) instruments. The ADS 2 is an intelligent autodilution system, which includes an Advanced Valve System (AVS). The system improves the productivity of ICP-OES workflows by automating many manual tasks throughout the analytical sequence.
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.
