Simulated Moving Bed Chromatography: from chiral molecules to biocompounds
The Simulated moving bed (SMB) technology was developed in the '60s and used for large-scale separations of hydrocarbons in the oil industry. The SMB concept has been extended towards new fields of application since then, first in the large-scale food industry, e.g. separation of sugars, and lately in the separation of fine chemicals, particularly chiral molecules where it is now an established technique more
Separation of Nadolol Stereoisomers by Chiral Liquid Chromatography at Analytical and Preparative Scales
ABSTRACT The separation of the four nadolol stereoisomers on Chiralpak® AD by chiral liquid chromatography was carried out at both analytical and preparative scales. A screening of possible mobile‐phase compositions was performed using different alcohol–hydrocarbon mixtures. The results obtained more
ChemInform Abstract: Additive‐Assisted Synthesis of Boride, Carbide, and Nitride Micro/Nanocrystals.
Abstract A series of boride (TiB2, ZrB2, NbB2, CeB6, PrB6, SmB6, EuB6, LaB6), carbide (SiC, TiC, NbC, WC), and nitride (TiN, BN, AlN, MgSiN2, VN) micro/nanocrystals are prepared from the corresponding metal oxides and amorphous boron/active carbon/NaN3 in the presence of metallic Na and elementa more
Identification of novel penta- and hexamethylated branched glycerol dialkyl glycerol tetraethers in peat using HPLC-MS2, GC-MS and GC-SMB-MS
A Siberian peat contains a high abundance of three unknown isomers of hexamethylated branched (br) GDGTs, of which two are present as a second peak eluting shortly after the known hexamethyl br GDGT containing two 5,13,16-trimethyloctacosanyl moieties. Tandem high performance liquid chromatography- more
