  • Chromatography - The Science of Separation
    that can be employed to separate individual compounds from the bulk sample, including extraction, precipitation, and perhaps most often, chromatographic separation. Chromatographic separation is based on the principle that a sample can be separated in time by passing it through a column which contains
  • Chromatography Roundup
    While truly groundbreaking innovations in chromatography equipment happen every blue moon, there have been noteworthy gradual improvements in the areas of chromatography media, column packing and on-line buffer blending, say Howard Levine (president) and Tom Ransohoff (consultant) of BioProcess
  • Introduction to Gas Chromatography
    that can be employed to separate individual compounds from the bulk sample, including extraction, precipitation, and perhaps most often, chromatographic separation. Chromatographic separation is based on the principle that a sample can be separated in time by passing it through a column which contains
  • Therapeutic Dose: Chromatography Dreams
    This quick, one-time registration gives you access to members-only site benefits. By Paul Thomas, Managing Editor There was a healthy buzz at last month s Pittcon show in Orlando over a chromatography column called Primesep, a sleek little unit combining reverse phase and ion-exchange separation
  • Selecting Makeup Gas for GC with FID (.pdf)
    When gas chromatography is employed for the detection of trace compounds, the characteristics of the carrier gas used for the actual separation and the gas used for detection may be significantly different. As an example, the carrier gas flow rate is selected to provide optimum resolution
  • Classification of Silica Gels Using Particle Shape (.pdf)
    Silica gels are used for a variety of applications, the most common being as a dessicant found in packages in order to keep the contants dry. Silica gels are also often used in Chromatography Column packing. Both the size and the shape of the silica have an effect on the quality and discrimination
  • SMB Takes On Paclitaxel Purification
    the molecular structures of the two compounds are very similar. The overall process, from starting biomass to finished product, is outlined in Figure 1. Bioxel has been producing paclitaxel since 1998 using single-column batch chromatography to remove cephalomannine. However, as demand for paclitaxel
  • SMB Takes On Paclitaxel Purification
    asynchronously across the ring of chromatographic columns. A six-column SMB configuration was established with solvent flow rates, operating pressures, switching times, feed concentration and feed flow rate. The model was used to project the economics of a large-scale SMB separation process
