Web26 feb. 2024 · However, IPA use is limited due to its high viscosity (leading to low performance and high back pressures), whilst THF can degrade pump seals, along with PEEK tubing and fittings and requires the use of stabilising agents such as BHT to prevent peroxide formation. WebHydrophobic interaction chromatography (HIC) is a technique for separation of proteins including monoclonal antibodies. The HIC mobile phase usually consists of a salting-out agent, which at high salt concentration, retains the protein by increasing hydrophobic interaction between the protein and the stationary phase.
WebHigh Strength, Long Life Sterilizing Filters for Air and Gas. Emflon® PFR filters have been developed from the successful Emflon filter range launched in 1981 and widely used as … WebIn addition, as IPA keeps increasing, WCA increases first, and then decreases gradu-ally. The possible reason for this phenomenon is the changing of surface roughness at different volume ratios of TEOS and IPA. As shown in figure 3, when the volume ratios of IPA and TEOS are 2:1 or 5:1, the surface exhibits superhydrophobic properties.
