Driven by specific directives from worldwide authorities, the integration of biodiesel—an alternative fuel derived from renewable sources like organic waste and vegetable oils—into standard petro-diesel blends is being heavily promoted globally. However, to ensure optimal engine compatibility, emissions control, and product consistency, this biodiesel must strictly adhere to a comprehensive set of quality requirements defined by established EN and ASTM standards.
Addressing these intensive analytical needs, the GAS Biodiesel Analyser offers an incredibly efficient, cost-effective setup specifically engineered to report critical parameters such as FAME and residual Methanol content. For EN 14103 (FAME and ester content), the system utilizes an SSL liquid injector with an Rtx-WAX column and FID. Simultaneously, EN 14110 (methanol content) is executed via headspace injection using an Rxi-1 column. Each method operates on its own dedicated analytical channel. For maximum productivity, laboratories can optionally integrate EN 14105 and ASTM D6584 (glycerol and glycerides) using a secondary gas chromatograph. The entire workflow is managed by a single Triplus RSH autosampler, automating everything from methyl ester preparation to standard dilution. The operator simply weighs the sample and loads the tray, leaving the system to deliver highly reproducible results in a rapid 27-minute runtime.
