Summary As the development of our society, industrial waste, pesticide residues, municipal solid waste are threatening our life quality and bringing harm to our health. So we should protect our environment with the help of high technologies, such as, liquid chromatography mass spec. Body The application of liquid chromatography mass spec in environmental protection The wide use of LC Mass Spec in environmental protection has contributed a lot to water pollution, air pollution, noise pollution, radioactive pollution. Among the pollution of environment, water contamination is the most widely andhazardous for us. The main factors of water contamination are like following: Inorganic contaminants: various toxic metals and their oxides, acids, alkalis, salts, sulfides and halides. Organic pollutants: pollutants plastics, synthetic fibers, synthetic rubber, detergents, dyes, solvents, paints, pesticides and so on. Why can LC Mass Spec be widely used in this aspect? It has its own advantages. It has the ability of good separation efficiency; selectivity is high; high sensitivity and analysis speed. Besides these advantages, the use range ofLC Mass Spec is expanding and it also can be used for the preparation of samples. LC technology in the process of nitro-benzene degradation This application can be a reference to the analysis theory of degradation nitro-benzene reduction. There are some mistake we may make during this process and we also put up with some solutions for you. Inadequate samples As for this mistakes, we can enhance the matrix environmental polar. If the sample in an organic solvent, we can change solvent into water or a buffer solution in order to ensure the normal retention. Incomplete purification Whashing it with different solvents and buffer solution to remove the interferences without eluting the target analyte.

Summary In our precious posts, we introduce winners of the Nobel Prize in the last decade. And from now on,
Summary The Nobel Prize in chemistry 2013 was jointly awarded to three distinguished scientists–Martin Karplus, Michael Levitt and Arieh Warshel. Who are they and what are their research fields? Here you can have a clear look at their life. Body Now I will introduce them one by one. Martin Karplus As an American theoretical chemist, Martin Karplus is an austrian-born person. He is not only the Theodore William Richards Professor of Chemistry but also a Director of the Biophysical Chemistry Laboratory. In 1950, Karplus earned an AB degree in Harvard College. And then in 1953, under Nobel Laureate Linus Pauling, Karplus got his PhD. We can figure out that Karplus is the most brilliant student from the words of Linus Pauling. He also had taught in the University of Illinois and then Columbia University before he moved to Harvard in 1967. As for the research field, Karplus devoted himself to many fields in physical chemistry, such as, chemical dynamics, quantum chemistry and molecular dynamics simulations of biological macromolecules, which is the most notable one. His current research is concerned with the properties of molecules of biological interest. Karplus had also been awarded for many kinds of awards, as well as the Nobel Prize in 2013. Michael Levitt Michael Levitt was born in Pretoria, South Africa. His family is Jewish family from Plunge Lithuania. Between 1960 and 1962, he attended the Sunnyside Primary School and Pretoria Boys High School. In 1963, Levitt studied at the University of Pretoria. And then he got his Bachelor of science degree in Physics in King’s College London in 1967. As a PhD student, he studied at Computational Biology at Peterhouse, Cambridge. Levitt was one of the first researchers to conduct molecular dynamics simulations of DNA and proteins and he also developed the first software for this purpose. And now, he is well known for predicting macromolecular structures with the developing approaches. In 2013, he was awarded with the Nobel Prize “for the development of multiscale models for complex chemical systems”. Arieh Warshel Born in 1940 in kibbutz Sda Nahum, Mandatory Palestine, Arieh Warshel is an Israeli-American biochemist and biophysicist. As a pioneer in computational studies on functional properties of biological molecules, he once served in the Israeli Armored Corps. After that, he got his BSc degree in Chemistry, Summa Cum Laude, in 1966 from the Technion, Haifa. His major research field is in introducing computational methods for structure function correlation of biological molecules. As well as, the Nobel Prize we mentioned above, Arieh Warshel had gotten many kinds of Honors and Awards. This is the basic introduction of the three Nobel Prize Winners in 2013. We hope you can get a lot from this post.—Creative Proteomics
