Nitrite, occurs naturally in the environment as an intermediate of the nitrogen cycle through microbial decomposition of organic matter. However, nitrite contains nitrogen in a reasonably unstable oxidation state and readily oxidizes to nitrate. As a result, nitrite is present at considerably lower ...
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 ...
The measurement of the band gap of materials is important in the semiconductor, nanomaterial and solar industries. This note demonstrates how the band gap of a material can be determined from its UV absorption spectrum.
All medicinal products need to be protected and packaged in containers which conform to prescribed standards. The quality of pharmaceutical packaging can have a significant impact on the performance of pharmaceutical products and can reduce shelf-life if the improper packaging is used. The USP chapt ...
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 ...
Nanomaterials are infinitesimal, but do not let their size fool you. Their surface area actually increases at the nanoparticle scale to infuse these miniature building blocks with unique magnetic, mechanical, structural, optical, and electrical properties that are different from the same chemical at ...
Chromium (VI) ions react with diphenylcarbazide in weakly phosphoric solution. The product, diphenylcarbazone, is a red-violet complex which can be detected photometrically at 550 nm. The chromate cell test kit is suitable for the concentration range of 0.11 – 4.46 mg/L chromate allowing the concent ...
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 ...
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 ...
