  • Comparison of different anion-exchange chromatography resins for the purification of cyanobacterial microcystins

    For the first time, different types of diethylaminoethyl (DEAE) anion-exchange resins, widely used in previous studies, were investigated to determine the most effective resin for the purification of microcystins (MCs). MCs were extracted from freeze-dried Microcystis aeruginosa cells that had been harvested from the Bueng Nong Khot reservoir, Khon Kaen, Thailand. The toxins were precipitated ...

  • Improved analytical techniques for Carbohydrates, Amino compounds, and Phenols: tools for understanding soil processes

    A process-level understanding of soil C and N cycling will be facilitated by accurate measurement of biochemical compounds in soil organic matter. This review summarizes some recent developments in analytical procedures for measuring soil carbohydrates, amino compounds (amino acids and amino sugars), and phenols. The emphasis is on methods for soil carbohydrates and amino compounds involving ...

  • Analytical Testing for Corexit Dispersants Used in the Gulf Spill

    The analysis of various sample matrices (seawater, sediment, tissue) to determine concentrations of Corexit dispersants used in the Gulf spill requires the use of one or more of the components in the dispersant as a tracer. The primary active ingredient (i.e. the primary surfactant) in the Corexit products is Dioctyl Sulfosuccinate Sodium Salt (DOSS). The other primary ingredients function as ...


  • USLC columns put the right tools in your LC method development toolbox

    Understanding Selectivity in Reversed Phase Separations – A Simplified Approach to HPLC and UHPLC Column Selection The most significant influence on chromatographic peak separation, or resolution, is column selectivity. Unfortunately, column selectivity is also the least understood and most underutilized parameter. To improve selectivity, method developers often concentrate on ...
