High resolution in gel permeation chromatography has been accomplished by use of long columns, since commercial rigid gels afford relatively fixed capacity ratios and since plate numbers of equivalent columns are additive. To overcome the high cost and high pressure requirement of long columns often ...
Potential of high temperature liquid chromatography for the improvement of separation efficiency—A review Analytica Chimica Acta Journal2009, Analytica Chimica Acta Thorsten Teutenberg 1 Introduction The potential of high temperature liquid chromatography has been discussed in the scientific literature ...
The crisis of antibiotic resistance has become an impending global problem. Genome sequencing reveals that streptomycetes have the potential to produce many more bioactive compounds that may combat the emerging pathogens. The existing challenge is to dev
Next, to elucidate the mechanism and regulation of RPA phase separation, we turned again to the cellular optoDroplet system for the following reasons: the induction of optoDroplets by blue light not only provides a means to reversibly trigger protein condensation in the natural environment of livin...
Liquid chromatography coupled to high-resolution mass spectrometry (LC−HRMS) is a reliable instrumental platform to perform non-targeted analysis with high molecular coverage of the non-volatile metabolome. Using time-of-flight (TOF) or Orbitrap instruments, HRMS provides high resolving power, allowi...
High-performance liquid chromatography (HPLC) analysis of pigments From the area between 1.5 and 3 cm below the tip, 1 cm long leaf segments were cut from plants in the climate chamber under the growth irradiance. After measuring the segments’ widths, these samples were immediately frozen in ...
The radiochemi- cal separation of the produced Pm isotopes from the Nd bulk material was performed by ion exchange chromatography on the SYKAM cation exchange resin, following the procedure described in [15]. As a tracer of the Nd-fraction during the chemical separation, 1 MBq of 147Nd was ...
Additionally, every feature with a retention time lower than 60 s or higher than 600 s was removed, since they were acquired during column acquisition or washing phase of the chromatography. According to Wehrens et al.20 feature abundances with a value of zero were replaced by the lowest...
Gel permeation chromatography (GPC). Analyses were performed on a Waters GPC system comprised of a Waters 1515 isocratic HPLC pump, using two 7.8 × 300 mm Styragel HR 4E THF (waters WAT044240), with a Waters 2414 refractive index detector. The system was calibrated using 14 polystyrene sta...
Microalgae (including the cyanobacteria) are established commercial sources of high-value chemicals such as β-carotene, astaxanthin, docosahexaenoic a
