A reconfigurable multi-mode post-column analysis system improves resolution of liquid chromatography detection data by providing a parking or MSMS detection mode in which flow of column eluent is substantially reduced to provide greater analysis time within a single eluting detection peak. The at least part of the inductor conductor segment extends through an insulating layer disposed between the conductive layers, or is embedded in the insulating layer, wherein the part of the inductor conductor segment has a thickness one-half or more the thickness of the insulating layer. The intensity of the scattered light is measured at many different angles, which determines both the amount of particulates in the sample, and detailed information about the particles such as average size, shape and composition. In addition, during the reaction stage, certain hard-to-separate contaminants, such as aluminum and polyvinyl chloride, can react to a form more easily separable from the polyester.
