Gel Permeation Chromatography (GPC) - Waters Corporation

2 In 1964 John C. Moore, of the Dow Chemical Company, published his work on the preparation of Gel Permeation Chromatography (GPC) and changed how scientists studied synthetic polymers and macromolecules.

Particle size: 5 µm, 3 µm, and smaller Monodispersed means particles are the same size Very important for stable pressure and flow Smaller particles produce higher system pressure Pore size: 100-120 A is typical Surface area: 300-350 m2/g/g Carbon load: 9 …

pH 4.2, was 0.1 mole of sodium acetate added to 900ml of water, and then titrated to pH 4.2 with acetic acid before bringing to 1L volume? If so, the acetate concentration will be significantly higher than 0.1M. Or, was the pH overshot, necessitating the addition of dilute NaOH to bring the pH back to target, increas-

A flow diagram of the procedure is shown in Figure 2.4.24.-5. When a residual solvent (Class 2 or Class 3) is present at a level of 0.1 per cent or greater then the content may be quantitatively determined by the method of standard additions. 124 See the information section on general monographs (cover pages)
