The diverse structures and pore topologies, accessible cages and tunnels, and high surface areas make metal-organic frameworks attractive as novel media in separation sciences. Here we report the slurry-packed MIL-101(Cr) column for high-performance liquid chromatographic separation of substituted aromatics. The

A dynamic mathematical model has been developed to predict the performance of a stirred tank, solid-liquid two-phase partitioning bioreactor (SL-TPPB) for the treatment of benzene, toluene, ethylbenzene and o-xylene (BTEX) contaminated gases. The SL-TPPB system consists of an aqueous phase

In this study, poly(ethylene glycol) (PEG) grafted onto multi-walled carbon nanotubes (PEG-g-MWCNTs) were synthesized by the covalent functionalization of MWCNTs with hydroxyl-terminated PEG chains. For the first time, functionalized product of PEG-g-MWCNTs was used as selective stationary phase to prepare

Cephalopods can display dazzling patterns of colours by selectively contracting muscles to reversibly activate chromatophores--pigment-containing cells under their skins. Inspired by this novel colouring strategy found in nature, we design an electro-mechano-chemically responsive elastomer system that can exhibit a wide

What are the percentages of each Xylene isomer found in product 320579, Xylene?
1 réponse-
According to data given by the supplier of product 320579, Xylenes, this product contains a minimum of 18.0% p-Xylene and no more than 20.0% Ethylbenzene (we allow for </= 25.0% on our Certificate of Analysis). Both o- and m-Xylene are reported as batch-specific values and will not have to meet a requirement as long as the sum of all Xylene isomers and Ethylbenzene are equivalent to 98.50% or more. In several batches, m-Xylene has appeared with a value of ~40% and o-Xylene with ~20%. These values may change on a batch-to-batch basis.*All percentages above are "wt %".
