Pentanol is an alcohol containing five carbon atoms. It has similar physical properties to those of diesel fuel, so it can be used to replace gasoline in internal combustion engines. Pentanol is also attractive as a diesel fuel additive because it inhibits particulate formation. As a C5 alcohol, pentanol emits less greenhouse gas and produces fewer harmful pollutants after combustion. Analyzing pentanol for trace elements is necessary since metal contamination will reduce engine performance.
ICP-OES is commonly used to analyze trace elements in pentanol. Like other organic solvent samples, pentanol has analytical challenges. The organic solvent sample introduction kit helps to overcome the common problems faced by ICP-OES in detecting trace elements in organic samples.
In addition, carbon emission during pentanol analysis interferes with the elements emitting light in the high visible range, such as sodium and potassium and thereby lowering their detection limit. To reduce interference during detection of sodium and potassium, compressed air can be added to the auxiliary gas. As a result, carbon species are converted to other species with different emission spectra and interference is drastically reduced.
