Several methods are used to measure viscosity, which is reported in terms of kinematic or absolute viscosity. While most industrial lubricants classify viscosity in terms of ISO standardized viscosity grades (ISO 3448), this does not imply that all lubricants with an ISO VG 320, for example, are...
A - What does the UV-Vis spectrophotometer measure? What is Beer's Law (you might have to look it up) and how does it relate to data collected from a spectrophotometer? B - What is a sample blank? What it is it used for in an experiment? C - What does ...
USP <1058> is an important document as it is the only risk-based regulatory guidance on the subject. USP <1058> is an informational general chapter (providing strong guidance) outlining a scientific and risk-based approach to AIQ, but it does not define the acceptance criteria for specific ...
Q: Is FTIR affected by the environment? Q: How deep does the infrared light penetrate at the position of contact between the prism and sample during ATR measurements? Q: What sort of sample concentration should I use for measurements by the KBr pellet method or diffuse reflection method? Q:...

What are the advantages of FTIR over dispersive IR spectroscopy? What property of fluorescence indicates that it is a spin-allowed process? Does this property also explain why phosphorescence is not spin-allowed? What is positive catalysis? Give a suitable example. In what kinds of conditions (li...
Infrared analysis is the second type of spectroscopy commonly found in a laboratory. Unlike elemental analysis, FTIR provides information on compounds, rather than elements, found in an oil. FTIR measures several useful degradation parameters, so is particularly useful in engine oil samples. Infrared ...
