A Novel, Simplified Methodology for the Analysis of Biodiesel by HPLC
June 1st 2010Biodiesel is generally produced by the transesterification of vegetable oil or animal fat with methanol. The triglycerides present in the feed oil (vegetable oil or animal fat) are reacted with methanol in the presence of KOH as the catalyst.
High Temperature Simulated Distillation: ASTM D 7169
June 1st 2010Robust hardware and automated software are critical to method ASTM D7169. The Shimadzu GC-2010, equipped with an advanced flow controller, has proven to be reproducible and effective, and Shimadzu distillation GC software has achieved automation by integrating calibration, integration, calculation, and report functions.
Profiling of Essential Oil VOCs and SVOCs by GC–TMS
February 1st 2010Spice and fragrance essential oil raw materials frankincense (Boswellia carterii) from India and Somalia, sandalwood (Santalum album) from India and Indonesia, and corn mint (Mentha haplocalyx) from the United States were analyzed for on-site analytical profiling and confirmation of quality and purity of therapeutic grade essential oils from raw materials.
Glycerin in Biodiesel by Capillary GC Analysis
June 1st 2009Biodiesel is much in the news today as an alternate fuel source that is safe and nontoxic. It is renewable, via farming and recycling, and is biodegradable. It is cleaner burning than petroleum-based gasolines, with virtually no sulfur and with no net carbon load to the atmosphere.
