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 ...
We evaluated a 3M® visible mirror film for potential use in a new curved photovoltaic module using a LAMBDA 950 spectrophotometer with an ARTA accessory. In this application, the 3M® film must transmit near-infrared photons to the underlying silicon solar cells (where they will be converted directly ...
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 ...
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.
The FDA defines data integrity as "completeness, consistency, and accuracy of data. Complete, consistent, and accurate data should be attributable, legible, contemporaneously recorded, original or a true copy, and accurate (ALCOA)". ALCOA itself has evolved to ALCOA Plus, which incorporates two of t ...
The data shows the suitability of the LAMBDA 265 for producing rapid, high-quality spectra. It also shows that the instrument is able to measure the higher nanoparticle sizes, even though these scatter light to a greater extent due to the increased particle size and also settle out more quickly.
Quantification methods for total protein are among the longest-established fundamental and important experiments of bioscience. UV/Vis Spectrophotometry is widely used for the determination of protein. This application note describes a typical protein method, the Bradford method. Data is rapidly acq ...
The 150 mm Integrating Sphere is the recommended accessory for measurement of total solar reflectance and transmittance in the glass industry and for the measurement of UV transmittance of paints and films in the automotive industry. Many national laboratories use it in R&D studies and for calibrati ...
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 ...
Optical filters have many functions, including color correction, used to improve color balance in many optical systems, to neutral density filters that produce specific reduction in the level of transmitted light. The characterization of these diverse optical filter types is critical from design thr ...
Advanced instrumentation is key to work in nano-materials. Functional tools such as optical and thermal measurement techniques allow the characterization of materials. As such, they complement imaging tools such as AFM and TEM-SEM which give spatial information on the structure of the materials. Thi ...
