Liquid Chromatography–Electron Capture Negative Ionization

Dec 13, 2021 · Negative chemical ionization (NCI) and electron-capture negative ionization (ECNI) are gas chromatography–mass spectrometry (GC–MS) techniques that generate negative ions in the gas phase for compounds containing electronegative atoms or functional groups. In ECNI, gas-phase thermal electrons can be transferred to electrophilic substances to produce M–• ions and scarce fragmentation

Solution Dilution Calculator - Sigma-Aldrich

The solution dilution calculator tool calculates the volume of stock concentrate to add to achieve a specified volume and concentration. The calculator uses the formula M 1 V 1 = M 2 V 2 where "1" represents the concentrated conditions (i.e., stock solution molarity and volume) and "2" represents the diluted conditions (i.e., desired volume and

There needs to be a centrifugation step in-between or something like that to allow you to concentrate more. If it was the other way round, e.g. the initial one is 0.25 diluted and the final one is 0.15, then you would need to add the difference between the two volumes stated above (26.7mL of water) to the 0.25 solution.

Preparation and characterization of gelatin sponge

Jan 10, 2009 · A novel method for the preparation of gelatin sponge millispheres (GSMs) for biomaterials such as embolic agents and cell scaffolds was developed using an air-in-water-in-oil-type emulsion. The droplets, consisting of a foamy gelatin suspension in caprylic triglyceride, were gelled and rinsed with isopropanol. Sonication and depressurization were used during the rinsing process to create
