Trace Elemental Analysis of Trichlorosilane by Agilent 7700s ICP-MS
Junichi Takahashi, Agilent Technologies
Metallic impurities in trichlorosilane (TCS) must be strictly controlled to produce the high purity PV silicon necessary for solar cell manufacturing. A successful analytical method was developed using an Agilent 7700s ICP-MS.
HPLC The Measurement of High Optical Densities (up to 8 Abs) in the Near-Infrared
Andrew R. Hind and Jan Wuelfken, Agilent Technologies
Demonstrates, using the addition of filters technique, photometric performance up to 8 Abs at 1200 nm in the NIR, and shows high optical density measurements in the NIR for various materials used in the manufacture of laser safety eyewear.
  Automated Circular Dichroism with Dynamic Multimode Spectroscopy: A Powerful Tool for the Optimization of Protein Conformational Stability
Lindsay Cole, Lisa McIntosh, and Chris van der Walle, Applied Photophysics Limited
The application of the DMS method on the Chirascan-plus automated circular dichroism instrument is a powerful tool for understanding the thermal denaturation pathway of proteins. As such, it is a very informative technique in directing optimization of protein stability by protein engineering or formulation activities.
  Analysis of Degraded Machine Oil by FT-IR
Shimadzu
The quality of machine oil can be adversely affected when used for extended periods of time from contamination and oxidation. In this note, multiple methods were used to evaluate degradation due to usage.
