“HPLC for Pharmaceutical Scientists” is a new hardcover book edited by Yuri V. Kazakevich and Rosario LoBrutto with a price tag of $159 at Amazon. This is an excellent book for both novice and experienced pharmaceutical chemists that provides a unified approach to HPLC with a balanced treatment of the theory and practice of HPLC […]
A few years back during my 3 month trip to China I remember noticing enormous number of pharmacies that sold traditional Chinese medicine. Everywhere I went in China they looked more or less the same just like an old-fashion pharmacy of the 1920s here in the West with its wooden drawers and cabinets full of […]

The large-scale studies of structure and function of proteins (proteomics) are performed using a variety of analytical techniques from two-dimensional gel electrophoresis, immunoaffinity chromatography to tandem and MALDI-TOF mass spectrometry. The words “large-scale” in proteomics definition refers to the fact that the number of proteins that need to be evaluated is enormous. For example, the […]
John J. Kasianowicz from NIST and his colleagues created a 2D method for mass spectrometry capable of a single-molecule analysis based on the interaction between a nanometer-scale pore and analytes. The method is a “nano” version of Wallace Coulter patented technique that detects particles suspended in solution by driving them through a capillary which is […]
The researches inadvertently discovered that they can write and erase on the surface of liquids – the method that could one day be applied to high-density data storage, making templates for etching silicon chips (photolithography) and a variety of other materials applications. Peter Licence at the University of Nottingham, UK, and his colleagues were using […]

This is another Q&A from Yahoo! Answers which I could not stay away from. The question was asked by “pigpigletpoker” and has already received two answers. Dave_Stark said: Make a chromatogram of the paint found on the other car involved in the accident. Then do a side-by-side chromatogram of the red paint from the two […]
