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 increase ...
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 calibr ...
Combination drugs containing Paracetamol and Aspirin are widely used analgesics with anti-inflammatory properties for treatment of migraines. UV/Vis spectrometry is a fast and commonly used technique in quality control laboratories for routine analysis of purity and quantity of components within ...
In surface waters, phosphorus commonly exists in its phosphate form. A high concentration of phosphate in water is indicative of domestic waste, industrial effluent, and agricultural runoff which can lead to eutrophication. Eutrophication causes an increase in plant and algal growth, which decreases ...
In this application, the quantitative analysis of formaldehyde was successfully executed using the LAMBDA 265 UV/Vis spectrophotometer and Merck Spectroquant formaldehyde cell test kit. Principle Formaldehyde reacts with chromotropic acid in sulphuric solution to form a violet dye which can be detec ...
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 preve ...
Determination of nucleic acids is a common procedure in most molecular laboratories. Accurate and rapid method to quantify DNA is essential to obtain reliable outcomes. Fluorescence spectroscopy offers a simple yet highly sensitive technique to determine low amounts of DNA in solution (even in bi ...
Ammonia-nitrogen (NH3-N) occurs naturally in groundwaters at concentrations below 0.2 mg/L and up to 12 mg/L in surface waters, as a result of decomposition of organic matter. High concentrations of ammonia in surface waters are toxic to aquatic life and are indicative of contamination from industri ...
Spectrosopic techniques, such as UV-Visible spectrometry, can be deployed to observe the chemical changes taking place during fast reactions. However, in many cases the reaction timescales are too fast to be performed and observed by the simple manual mixing of the reactants in a cuvette. The sto ...
Historical manuscripts are subject to deterioration due to aging processes under different storage and handling conditions. There can be physical, chemical and biological factors with different impact on papers and parchments or inks and dyes. Optical methods are preferred for the evaluation of h ...
Clinical chemistry uses chemical processes to measure levels of chemical components in the blood. It is very useful for the early diagnostic of disease and for monitoring organ function. The most common specimens used in clinical chemistry are blood and urine and this application note shows the comm ...
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 ...
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 ana ...
