Results show that simple alcohols (methanol, ethanol) or alkanes (heptane, hexane) are environmentally preferable solvents, whereas the use of dioxane, acetonitrile, acids, formaldehyde, and tetrahydrofuran is not recommendable from an environmental perspective. Additionally, a ...

Over the years chromatography has gained an enviable position in analytical laboratories. You have been introduced to simple concepts on how to read a chromatogram.
Stocks of acceptors showing low solubility were prepared by adding an appropriate organic co-solvent. The content of co-solvent in the reaction was set at 10% (v/v) for ethanol (EtOH) and methanol (MetOH) and at 5% (v/v) for acetonitrile (ACN) and dimethyl sulfoxide (DMSO) to ...

Peptides were labelled with TMT10plex Isobaric Label Reagent Set (Pierce), desalted using Oasis HLB cartidges (Waters) and subjected to a reversed-phase fractionation on a 0%–90% Acetonitrile in 10mM Ammonium Formate (pH10) gradient. Twenty...
About one third of vascular plants develop glandular trichomes, which produce defensive compounds that repel herbivores and act as a natural biofactory for important pharmaceuticals such as artemisinin and cannabinoids. However, only a few regulators of
a ACQUITY HSS T3 column (2.1 × 100 mm, 1.8 μm) in positive mode. The mobile phases consisted of water/formic acid (1000/1, v/v) as solvent A and methanol/acetonitrile (3/2, v/v) as solvent B58. Elution was started under isocratic conditions of 40% of solvent B for...
