Latest Applications SciMed Applications Testing the quality of biodiesel What is biodiesel? Biodiesel represents a popular, renewable alternative to traditional petroleum-derived fuels. Its carbon neutral footprint, sustainability and economic viability have brought it sharply into consideration as a substitute and supplement for middle distillate fuels. Biodiesel is synthesised by transesterification of triglycerides into mono-alkylated, fatty esters and glycerine. Why is biodiesel quality control testing important? In the early 2000s, insufficient regulation on biodiesel production led to multiple mechanical issues, such as engine clogging. As biodiesel is less stable than petrodiesel, it is more vulnerable to oxidation. The products of this…
Zeolites are commonly used in a vast variety of industrial applications, including environmental clean-up, petroleum cracking, filtering/separations and cation exchange. These materials can be mined from natural sources or can be commercially synthesized. A basic structure of five silicon and aluminum tetrahedra result in a cage-like structure with large open spaces or “pores”. These pores have charged regions which attract or exchange cations. For effective activity and specific cation incorporation, the zeolites need to be very specific and pure
Crude oil contains sulfur in concentration from 0.5 mass% to 5.0 mass% typically, and sulfur is one of critical elements in refinery processes and final products. Sulfur in petroleum-based fuels contributes to atmospheric pollution; therefore, sulfur content in fuels, especially in automobile fuels, is strictly controlled. Sulfur also causes damage to process components such as catalysts in refinery processes. Therefore, control of sulfur content is very important in the petroleum industry from the standpoints of both environmental and production costs. X-ray fluorescence (XRF) spectrometry has been used for quantitative analysis of sulfur in petroleum products, owing to simple sample preparation….
Phosphorous, sulfur and chlorine are commonly analyzed elements in liquids such as petroleum products and organic solvents.

For those labs requiring high sample throughput each day, not only accuracy, precision…
The analysis of trace elements in seawater is one of the most challenging analytical tasks in the field of environmental monitoring – the trace element concentrations are usually quite low, often in the low ng/L range, and the seawater matrix causes interferences from its high dissolved salt content. For ICP-MS, the seawater matrix is challenging physically and chemically. Continuous nebulization leads to salt deposition on the sampler and skimmer cones, resulting in a loss in sensitivity and poor long-term stability. The chemical composition of the sea water matrix causes polyatomic ion interferences and non-spectroscopic interferences, particularly for the determination of…
Mercury is a well-known toxic element and considered as one of the top ten chemicals of public health concern by the World Health Organization.

Chapter and ICH Q3D specify maximum limits for the amount of elemental impurities permitted in drug products, drug substances, active ingredients and excipients. These impurities may be present naturally, derived from the production catalysts or introduced inadvertently through the manufacturing process, or they could be environmental contaminants in the pharmaceutical raw materials. When elemental impurities have the potential to be present, compliance to the specified levels is a requirement. Here we present a simple and effective method for routine preparation and analysis of pharmaceutical material according to ICH and USP 232 and 233.
