Results: After inspection the factors of different ion pair reagent and ionic strength which effect the system peak and the system peakeffect analytic peak, the original method was improved.
As a report commissioned by the US Department of energy shows, an emergency programme to replace current energy supplies or equipment to anticipate peak oil would need about 20 years to take effect.
