Specific surface area: The neglected parameter in chromatography

摘要: Abstract The specific surface area of chromatographic supports, the importance which has long been recognized, is still a neglected parameter. Nevertheless, this parameter can open up new possibilities in chromatography general. appears theoretically retention time expression and rules that ogovern separation gas liquid are similar. When applied partition chromatography, large values permit high-speed analyses high resolution on very short columns, could lead to process air pollution analysis. when adsorption permits used low pressure inexpensive high-performance by using short, efficient columns. use Spherosil with both illustrated some typical examples.
