WebI have found this works well. Make sure your reservoirs/frits are clean and flush the HPLC at a low flow rate (~0.05-0.1 ml/min) with 50% iPrOH/40% H2O, and 10% AcOH for a couple of days. Do not send this to the MS source, but either divert to waste or disconnect solvent line form the MS and place in a waste receptacle. WebThese metals, as well as their oxides, carbides, nitrides, and sulfides can specifically catalyze chemical reactions. They have many low-energy surface electronic states (19) that can donate or accept electrons when bonds are formed or broken on the surface.

In 1990, 45,000 metric tonnes of isopropyl alcohol were used in the United States, mostly as a solvent for coatings or for industrial processes. In that year, 5400 metric tonnes were used for household purposes and in personal care products. Isopropyl alcohol is popular in particular for pharmaceutical applications, due to its low toxicity. Some isopropyl alcohol is used as a chemical intermediate.
