Absorbance spectroscopy offers users the opportunity to gain new insight into samples across a wide range of industries, not least the water industry. This powerful method is ideal for verifying the ...
A vital component in many research fields is the ability to measure bacterial growth for fermentation, antibiotic effectiveness, synthetic biology, and food safety. Estimating bacterial growth ...
ELISA kits have been integrated into many laboratory environments. Countless hours have been spent looking for ways to simplify the complex chemistry in these kits. Researchers are always ...
New Tools Bridge Gap between Single and Multiple Sample Absorbance Instruments For generations after Gustav Kirchhoff and Robert Bunsen deduced that almost all molecules in nature absorb and emit ...
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 ...
The success of next generation sequencing or western blotting is often affected by sample quantity and purity. To assess these parameters, researchers measure sample absorbance or fluorescence.
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 : ...
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 ...
