Título: Análisis de trazas de elementos en pentanol utilizando ICP OES.

 Título original: Analysis of trace elements in pentanol using the Thermo Scientific iCAP 7000 Series ICP-OES.

Introduction

Pentanol is used in many fields of applications, for example the manufacture of corrosion inhibitors, fuel and lubricating oils additives, cosmetics and pharmaceuticals. Besides its current use as a fuel additive, pentanol is also a promising drop-in fuel. It could be used as a direct replacement for gasoline, without the need for major changes to infrastructure, such as pumps and pipelines. Currently, the main source of pentanol is synthetic hydrolysis of halogenated pentanes. However, researchers are exploring a variety of new technology pathways to produce hydrocarbons, including the use of algal and bacterial mass cultures.  These are able to produce C4 and C5 alcohols, which have energy contents similar to that of gasoline. Unlike other biofuels produced from rape seed or wheat, the production does not compete with food crops and therefore it offers an alternative fuel for future purposes. As the fuels are derived from biomass they are also approaching carbon neutrality. All of these applications require that manufacturers comply with the according regulations, to ensure that certain elements do not exceed the corresponding limit concentrations of trace elements.

 

Instrumentation

For this analysis the Thermo Scientific™ iCAP™ 7600 ICP-OES Duo was used with the organics sample introduction kit, consisting of a V-groove nebulizer, baffled spray chamber, 1 mm center tube and organics pump tubing. The iCAP 7600 ICP-OES Duo was chosen due to its low detection limits for elements of interest and to demonstrate its capability to handle complex sample matrices.
