Extractables and leachable are typically studied using chromatographic techniques. This study explores what we can learn by using from using Raman microscopy for such studies.

We continue our survey of the spectra of carbonyl-containing polymers by looking at cellulose acetate and the economically important polycarbonate Lexan.

To conclude this four-part series of spectroscopic instrumentation and components, we examine spectroscopy electronics, including printed circuit board (PCB) design and manufacturing, spectroscopy instrument design services, instrument testing services, and the firmware and software aspects of instrumentation.

By using green synthesized AgNPs modified by chitosan and organic acid, a simple, cost-effective, and highly selective onsite colorimetric detection method for Pd2+ and Hg2+ ions was developed.
