Scientists, QA/QC analysts, and lab technicians in a wide variety of fields need to analyze samples quickly, accurately, and easily through their UV-Vis systems.

QA/QC analysts and lab technicians in a wide variety of fields – pharma and biopharma, applied materials, optics, food, and academia among them – need to analyze samples quickly, accurately, and easily through their UV/Vis systems, with better turnaround times, confidence in results, and increased p ...

UV/Vis spectrometers are highly versatile instruments employed in a wide variety of applications. The development of microvolume cuvettes that can be easily fitted in UV/Vis spectrometers allows ultra low sample volumes while maintaining the desired accuracy. In this application, the LAMBDA® 365+ UV ...

UV/Vis spectroscopy represents a powerful technique to study any analyte that is able to absorb light in the UV and Visible region of the electromagnetic spectrum. When proteins contain aromatic side chain amino acids and disulfide bonds,1 these complex biomolecules fall into this category of analyt ...

Quantification of RNA can be easily carried out exploiting the Beer-Lambert’s Law which defines the direct proportion between the concentration of a sample and the quantity of light absorbed. Based on the presence of purine and pyridine heterocyclic aromatic rings, nucleic acids are able to absorb l ...

a-chymotrypsinogen is a precursor, or zymogen, of chymotrypsin. Chymotrypsin fulfils the role of breaking down proteins into smaller peptides in the digestive tract. It also displays an interesting property in that, when it unfolds due to thermal denaturation, it is able to refold when cooled back t ...

Engine coolants are an important fluid sometimes neglected in motor vehicles. Some citations in the literature report that a major cause of engine failure behind lubricant failure, is that of the coolant. Nitrite (NO2-) is a common additive to coolant formulations that is used to prevent pitting of ...

All pharmaceutical packaging systems need to comply with performance requirements to guarantee the integrity and safety of the contained drug throughout its lifecycle, from manufacturing to distribution and ultimately to the end-user. Monitoring spectral transmission helps ensure that the container ...
