  • Instrument-based chromatography is now, for all practical purposes, a mature and well-established field. The days of the necessity for intensive training on the theories underpinning the technology simply to provide competent use have long since passed. Now the requirement is for the analyst to be competent and proficient in the use of the technology, to produce reliable and defensible results on a routine basis with little or no formal guidance. I have found that this is case in my laboratory, and I believe the basic scenario is the same in laboratories throughout the world....

  • Petroleum mixtures consist primarily of relatively unreactive complex hydrocarbons covering a wide boiling range. Such mixtures are difficult to separate by most analytical techniques. Therefore, the petroleum industry has for many years played a leading role in the development of chromatographic methods of analysis. Since the last book specifically concerned with chromatographic analysis of petroleum appeared 15 years ago, numerous advances have been made including developments in liquid and supercritical fluid chromatography, ...

  • Gas chromatography – chromatography using a gas as the mobile phase and a solid/liquid as a stationary phase – In GC, the analytes migrate in the gas phase, so their boiling point plays a role – GC is generally applicable to compounds with masses up to about 500 Da and with ~60 torr vapor pressure at room temp (polar functional groups are trouble) Supercritical fluid chromatography – chromatography using a supercritical fluid as the mobile phase and a solid/liquid as a stationary phase – In SFC, the analytes are solvated in the supercritical fluid – SFC is applicable to a much ...

  • This book presents a critical review of various chromatography techniques for a limited number of processes. Most techniques are illustrated by examples. The processes described are necessarily limited to those which appear to the authors to have the greatest validity and practical use. Wherever possible, we have included recommendations delineating the best techniques for analyzing each sample. Recommended techniques are often illustrated by detailed examples.

  • Chromatography is the separation method for biological molecules from the analytical to the preparative scale. Few of the recent advances in life science, whether in "proteomics" or in the industrial production of recombinant therapeutics, would have been possible without the help of chromatographic separations. Concomitantly, chromatography nowadays stands for much more than a batch column packed with porous particles

  • Gas Chromatography Mass Spectometry (viết tắt là GC-MS hoặc GCMS, tạm dịch là Phương pháp Sắc ký khí kết hợp với Khối phổ) là một phương pháp mạnh mẽ với độ nhạy cao được sử dụng trong các nghiên cứu về thành phần các chất trong không khí. Bản chất GC-MS, đúng như tên gọi của nó, là sự kết hợp của Sắc ký khí (Gas Chromatography) và Khối phổ (Mass Spectometry).

  • Biotherapeutics have become the main drivers for the pipeline of the pharmaceutical industry, and carry hope for millions of patients for a better life with, or even cure from, diseases for which there are no existing effective treatments. This group of medicines includes, but is not limited to, protein and nucleic acid-based therapeutics as well as different classes of vaccines and gene therapy treatments. Today, there are a few hundred licensed biotherapeutics produced from genetically engineered cells and over a thousand are in pre-clinical and clinical studies....

  • High-pressure liquid-solid chromatography (HPLC) is rapidly becoming the method of choice for separations and analysis in many fields. Almost anything that can be dissolved can be separated on some type of HPLC column. However, with this versatility comes the necessity to think about the separation desired and the best way to achieve it. HPLC is not now and probably never will be a turn-key, push-button type of operation.
