Rigid chromatography resins, such as controlled pore glass based adsorbents, offer the advantage of high permeability and a linear pressure-flow relationship irrespective of column diameter which improves process time and maximizes productivity. However, the rigidity and irregularly shaped nature of these resins often present challenges in achieving consistent and uniform packed beds as formati...

The present study investigates how advice writers employ move sequences and modal verbs to achieve intended discourse functions. This paper aims to testify two research hypotheses: 1. Advice writers of different topics employ different moves and modal verbs to achieve discourse function, and 2. The differences may imply writers’ intentions, emotion and expectancy of effects on the readers to in...

One of the fundamental attributes a liquid chromatography column is its stability when exposed to acidic and basic mobile phases. However, there have been relatively few reports date on hydrophilic interaction (HILIC) columns. Here, we report results evaluations carried out for HILIC columns packed with ethylene-bridged hybrid or silica particles using accelerated conditions, employing 100% aqu...
