Controlling trace impurities in a dividing wall distillation column
Dividing wall distillation columns (DWCs) separate a feed mixture into three pure product streams using one column shell. Though attractive due to capital and operational savings, DWCs have yet to gain widespread industrial acceptance. One notable concern is controllability. The research within …

Trace Evidence Analysis of Forensic Samples Using Inductively Coupled Plasma
… of minute samples, the better. For instance, trace elemental impurities are not regulated in many commercial materials and thus could be a unique identifier. One of the best techniques for multi-elemental trace analysis is inductively coupled plasma (ICP) spectrometry; yet, it is seldom used …

Effect of carbohydrate degradation upon browning and corrosion in canned applesauce
… formed under these conditions. The presence of trace metals in food products, whether they originate from processing water or from corrosion reactions, influence the dissociation of the sugars and ultimately the color and the keeping quality of the canned products. A tentative explanation of the …

Investigation of the composition of linear alkylbenzenes with emphasis on the identification and quantitation of some trace compounds using GS/MS system in both electron impact and chemical ionization modes
… questions have been raised about the trace levels of unreacted raw materials, linear alkylbenzenes and minor impurities present in them. With the advent of modem analytical instruments and techniques, namely GCIMS, the opportunity has arisen to identify the exact nature of these …

Supramolecular effects in pyridinium compounds and their application towards practical redox flow battery systems
… species, suppress parasitic side reactions with trace contaminants, and provide resistance to electrochemical degradation at potentials more negative than any demonstrated for methyl viologen and its analogues to date. Host-guest binding is readily modulated by several independent parameters …
