(Nanowerk News) Researchers from the NIST Center for Nanoscale Science and Technology (CNST) and the University of Maryland have for the first time used photothermal induced resonance (PTIR) to ...
Individuals with hypercalciuria have kidneys that put out higher levels of calcium in urine than normal, which increases their risk of developing kidney stones. Only a portion of hypercalciuric ...
NanoDrop™ Microvolume UV-Vis Spectrophotometers from Thermo Scientific™ are robust, useful analytical tools, ideal for measuring absorbance when working with small sample volumes. Thermo Scientific ...
L'absorbance mesure la capacité d'un milieu à absorber la lumière qui le traverse. On l'appelle également densité optique ou extinction. Il s'agit d'une grandeur sans unité donnée par la relation : ...
Proteins containing the appropriate amino acids are absorbent to light on the UV-spectrum, specifically light that has peak wavelengths of 260 – 280 nanometers (nm). This makes it simple to analyze ...
Cet article a été co-rédigé avec Monique Henry du CEGEP de St-Laurent (Québec). De nombreux composés organiques que l'on retrouve dans les eaux naturelles et traitées absorbent fortement dans ...
