In physical chemistry, the Arrhenius equation is a formula for the temperature dependence of reaction rates.The equation was proposed by Svante Arrhenius in 1889, based on the work of Dutch chemist Jacobus Henricus van 't Hoff who had noted in 1884 that the van 't Hoff equation for the temperature dependence of equilibrium constants suggests such a formula for the rates of both forward and

1995/1/1 · The prepared mobile phase was filtered through a 0-5 ju,m PTFE membrane filter and degassed using ultrasonic agitation. The sol- vent reservoir was equipped with a helium degassing facility. The flow rate was 1-5 ml/min. Samples were injected via a model 7125 Rheodyne syringe loading sample injector fitted with a 50 JU,I loop (Rheodyne, Cotati, Cal., USA).

Membranes are constructed of cellulose or other polymer material, with a maximum pore size set during the manufacturing process. The require-ment is that the membranes prevent passage of particles the size of microorganisms, or about 1 micron (0.001
