Reliable Elemental Analysis for Nitrogen, Sulfur, and Chlorine in Biofuels
First-generation biofuels are already widespread and well established. These are manufactured using processes such as the fermentation of sugar and starch and the hydrocracking of vegetable oils and animal fats. Hydrocracking is a catalytic, hydrogen-based cracking process for producing hydrocarbons of higher molecular weight. Innovative technologies that can extract biofuels from cellulosic ...

Zebra mussels (Dreissena polymorpha) as a biomonitor of trace elements along the southern shoreline of lake michigan
The invasive zebra mussel (Dreissena polymorpha) has become an accepted biomonitor organism for trace elements, but it has yet to be studied along the Lake Michigan shoreline. Likewise, the relationships between tissue concentrations of elements, organism size and sediment concentrations of elements have not been fully explained. This study found that a variety of allometric variables such as ...

The Analysis of Trace Elements in Boric Acid by ICP-MS
Until now, the trace analysis of aluminum in boric acid has not been feasible by ICP-MS due to spectroscopic interference by boron oxide and hydroxide. This note describes the use of an ultrasonic nebulizer with membrane desolvator to eliminate both the matrix and water from the sample, thereby removing the interferences. The detection limit obtained for aluminum in 1% boric acid was less than 50 ...

The Bending of a Screw Plate
The bending of a screw plate may have a considerable influence on the value of soil modulus derived from test results. This paper presents the dimensionless results of a study in which the plate is analyzed by finite elements and the soil is analyzed by integrated Boussinesq theory corrected for embedment in the medium. These results enable correction for the effect of plate bending for a range ...

How to Know Which Surface Analysis Instrument to Choose
The features and characteristics of solids are largely dependent on their chemical structure at the surface. Surface analysis is used to determine the chemical structure of the surface number atomic layer (a shallow and thin area of the surface). Surface analysis instruments analyze the elemental composition and chemical state of materials that are present in the surface number atomic layer ...

Linking trace element variations with macronutrients and major cations in marine mussels Mytilus edulis and Perna viridis
Marine mussels have long been used as biomonitors of contamination of trace elements, but little is known whether variation in tissue trace elements is significantly associated with those of macronutrients and major cations. Here, we examined the variability of macronutrients and major cations and their potential relationships with bioaccumulation of trace elements. We analyzed the ...

Microwave Digestion Method Applied to Alumina Samples
Aluminum oxide has high thermal and chemical stability, and can be used for high-temperature insulation, making heat shields or protective coatings. When making other materials, the purity of alumina should be very high, and the impurity elements of the material have a great influence on the performance of the final product. When analyzing trace elements in alumina, the most important step is ...

Continuous measurement of Process oxygen for Claus sulfur recovery unit (sru) start-ups and shut-downs case study
During start-up and shut-down, any time a sulfur recovery unit (SRU) transitions from ambient temperature through fuel gas warm up to the introduction of acid gas, measurement of 02 stoichiometry is critical. Historically, operators have manually taken samples using a portable electrochemical type Os analyzer. While giving more or less satisfactory results, the requirement for more stringent ...

Establishing wear particle limits using the theory of Dynamic Equilibrium Condition (DEC) to predict when abnormal wear modes are taking place in machinery
The basis of modern oil analysis programs is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants, and additives in oil samples. Whatever an oil lab may need to measure, multi-elemental analysis is the core of an in-service oil analysis program. This paper gives an overview of Rotating Disc Electrode Optical Emission ...

Analyzing sulfur in soil and sediment with handheld XRF
Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...
