Biopharmaceuticals have revolutionized the field of medicine in the types of active ingredient molecules and treatable indications. Adoption of Quality by
Raman spectroscopy is increasingly being used in biology, forensics, diagnostics, pharmaceutics and food science applications. This growth is triggered not only by improvements in the computational and experimental setups but also by the development of chemometric techniques. Chemometric techniques are the...
We present a joint experimental and computational terahertz (THz) spectroscopy study of the most stable polymorph (form I) of an antihypertensive pharmaceutical solid, felodipine (FLD). The vibrational response has been analyzed at room temperature by combining optical (THz-TDS, FT-IR, THz-Raman)...
The liquid-solid transition is a first-order physical phase transition, and as such, one would expect that the monitoring of macroscopical thermophysical properties, such as density, viscosity, etc. should be enough to unequivocally pin-point it. The reality is that n-alkane crystallization is a...
Spectroscopy Solutions for Pharmaceuticals: Confidence in Compliance to USP <857> Using the Agilent Cary 60 UV-Vis Spectrophotometer White Paper Introduction UV-Vis spectroscopy is one of the most commonly used analytical techniques in clinical chemistry, pharmaceutical research, and quality control/...
PDF Tools Share Abstract High-strength copper contact wire is of great significance to the electrified railway power supply system, which constantly provides electric power to the trains during operation. However, contact wire is subject to pressure, vibration, and natural forces such as wind, rain...
An apparatus and a method are disclosed for use with Laser Induced Breakdown Spectroscopy (LIBS) systems that can be applied to the real time analysis of molten materials or liquid. Since it is difficult to prepare a surface representative of the bulk when dealing with high temperature molten ma...

Spectrometer Using an Array Detector In almost all NIR and IR spectroscopy solutions, especially beyond 1.7 μm, the detector must be aggressively cooled below ambient in order to reduce the effects of dark current, and to improve dynamic range. This is usually accomplished with a single- or ...
