IN some instances poor efficiency with capillary columns has been reported, especially when glass capillaries were used. This may be due to two quite different phenomena : bad liquid-phase ...

DB-35ms columns are precision-engineered by Agilent to deliver excellent performance in a range of GC applications, particularly in confirmational analyses. The midpolarity columns operate over an ...

Agilent J&W DB-1ms is a nonpolar, low bleed column, with excellent inertness for acids and bases and an extended upper temperature limit. Using low bleed stationary phases in DB-1ms reduces column ...

Packed capillary columns for liquid chromatography were first reported in the mid to late 1970s. The first micro-fabricated column for gas chromatography was reported in 1979; however technological ...

Nucleic acid analysis, genotyping, PCR, and RFLP methodologies are time-consuming techniques using agarose or acrylamide gel electrophoresis—image capture plus gel image interpretations. Capillary gel ...

Mass spec–based methods coupled with chromatography separation techniques are fundamental to success in proteomics research and biopharmaceutical development, and low-flow liquid chromatography has ...

Prof. Barry has taught a wide variety of courses in Analytical Chemistry, including a graduate level course in chromatography and separation methods, his primary area of research. His research group ...

People across the globe use energy drinks to improve their concentration and productivity. One of the most efficient methods to analyze these beverages is capillary electrophoresis. This article looks ...
