Expanding the Legacy, the Arnel Clarus 600 GC Engineered Systems - NEW!

Petrochemical laboratories are concerned about producing quality data, but also about the ruggedness of analysis. Coupled with the need for rapid turnaround time, the challenge can be daunting. This talk will discuss the use of PPC for analysis in Arnel engineered Clarus GC systems. Increasing speed of analysis will be discussed using the 3023 Simulated Distillation, the 4035 LPG Analyzer and the 4050 DHA Analyzer as examples.

Efficient Quality Analysis of Biodiesel using GC - NEW!

Biodiesel is a renewable fuel alternative to petroleum diesel. It can be used in a pure form or blended with petroleum diesel to form a product that can work in conventional diesel engines without modification. The quality of the final product must be monitored to ensure reliable engine operation. Bound and free glycerin content can indicate the quality of biodiesel. A high content of free and total glycerin can lead to buildup in fuel tanks, clogged fuel systems, injector fouling and valve deposits. The analysis of biodiesel following ASTM methodology for glycerin by gas chromatography (GC) will be presented.

Meeting Low Sulfur Requirements in Fuel - NEW!

Sulfur in diesel fuel is often measured by gas chromatography. Inductively coupled plasma optical emission (ICP-OES) can provide a rapid analysis with little sample preparation. In addition, other metals can be measured at the same time, increasing productivity. This talk will focus on sulfur analysis by ICP-OES and the resulting figures of merit for the analysis to allow comparison with gas chromatography.

Biodiesel Analysis – Critical Quality Measurements

The use of alternative fuels such as biodiesel and ethanol is becoming increasingly important. Increasing gasoline prices and the desire for reduced pollution are leading drivers to consider conventional petroleum-based fuels substituted or blended with alternative sources of fuel.

Measurements during production are critical in producing a quality product that will give the highest performance. Testing to ensure compliance with BQ 9000 and ASTM 6751 specifications are described. Details of ASTM D6584 GC testing for free and total glycerin and elemental analysis of Na, P, S, and Ca by ICP-OES are presented along with sample preparation and analytical data. Several novel approaches using FT-IR are reviewed.
