Surfactants Analysis and Pharmaceuticals

Surfactants analysis and pharmaceuticals

Which titration suits your requirements best? Surfactant analysis does not follow the standard titration application profile. Anionic surfactant, cation surfactant, non-ionic surfactant, dual-phase titration; each has it’s own intricacy and fine-tuning. It is enough to make your head spin. Where do you start for the best analysis method? How do...

Trace analysis of Perchlorate in drinking water

Trace analysis of perchlorate in drinking water

Keeping our kids safe and healthy Low levels of perchlorate in our diet will have little short-term effect for healthy adults. For children, however, the negative effect on brain development can be considerable. Perchlorate directly effects the uptake of iodine by the thyroid. In adults, this can have an effect...

In situ SERS effect with screen-printed silver electrodes

In situ SERS effect with screen-printed silver electrodes

Metal screen-printed electrodes are promising, cost-effective SERS substrates. Metrohm Dropsens White Paper: In this white paper Alejandro Junquera Pérez, Pablo Fanjul Bolado, David Hernàndez Santos demonstrate the time resolved Raman spectroelectrochemistry measurements with screen-printed electrodes. The instrument used combines in a totally integrated box: a 785 nm laser source, a...

Top 7 reasons why you should use automated titration

Top 7 reasons why you should use automated titration

Accurate titration is required for all industries. Manual titration – although common – has its limitations. From wine to mining, titration in some shape or form is performed in practically every industry. When we first learn about titration, it is usually in the form of a tall glass burette, and...
