  • Determination of micro and macro elements in waters with the ELAN DRC-e

    The ability of reaction cell technology to reduce the effects of spectral interferences is well-known, but another, lesser-known capability also exists: extending the dynamic range. This is accomplished by adjusting the bandpass parameters with no gas in the cell. Because the bandpass parameters can be adjusted on a per-mass basis, sensitivity can be reduced on selected isotopes without affecting ...

  • What is a Spectrometer?

    The characteristics of a white LED light differs greatly, when compared to a yellow CFL. Without any special tools, one can see that the LED emits a clear white color, while the CFL generates yellow light. Going one step further, using a spectrometer, one will be able to “dissect” the light sources and see that they are composed of other colors in the visible light spectrum, such as ...

  • New ways for Metal Recycling

    REWAVE XRF 3-way-sorting in innovative  “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

  • Determination of macro, micro nutrient and trace element concentrations in Indian medicinal plants using instrumental neutron activation analysis and atomic absorption spectroscopy techniques

    Specific parts (fruits and seeds) of different medicinal plants often used in Indian Ayurvedic system were analysed for 18 elements (K, Mn, Na, Fe, Zn, Cu, Co, Br, Sm, Cl, La, Al, Cr, Ca Cd, Ni, Pb and Hg) by employing instrumental neutron activation analysis (INAA) and atomic absorption spectroscopy (AAS) techniques. The samples were irradiated with thermal neutrons in a nuclear reactor and the ...

  • EDXRF Analysis of Sulfur and Other Elements in Oil

    The concentrations of sulfur substances in fuel oil, which greatly contribute to air pollution and acid rain, are regulated by law in many countries, and these regulations are becoming stricter with the growing concern about their impact on the environment and the consequences for society. Here, using the easy-to-operate EDX-720 energy dispersive X-ray fluorescence spectrometer, we determined the ...

  • ICP Analysis of Multiple Elements in Drinking Water

    The amount of water typically consumed by an adult is said to be about two liters per day, and nearly all of this is tap water or mineral water, generally referred to as "drinking water." Conducting safety inspections are the responsibility of each country according to their respective regulations. Typically, there are many target elements included in the test, such as sodium (Na), calcium ...

  • Content Analysis of Toxic Elements in Soil by Simultaneous ICP

    Contaminated soil not only leads to contamination of untreated drinking water through permeation into river water and rainwater, it adversely affects health when the soil itself is directly ingested as a child puts the ground into a stoma into a play etc. Therefore, assessment of soil toxicity using a defined method is required. I In Japan, the Soil ...

  • Thermal analysis of smart fins in a micro heat exchanger

    Micro heat exchangers using smart fins undergo variation of temperature along the passage of fluid flow. This requires analysis of these smart cantilevers under thermal load. In the present research, thermal analysis of bi-metallic smart, surface mounted, piezo patched cantilevers under thermal excitation, has been carried out. Electro-thermo-elastic governing equations and constitutive equations ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Determination of Trace Elements in Lead for Battery Applications using Atomic Absorption Analysis

    Sample and Standard Preparation procedures for Trace Elements in Lead [1] Preparation of Lead (Pb) Samples: Drill Pb metal to make small pieces. Weigh 2.0 grams of these pieces on a balance. Place the sample in a 400ml Pyrex breaker and add 10ml H2O, 2.5 grams of tartaric acid and 7ml HNO3. Warm on a hot-plate until the sample dissolves. Dilute to 100ml in a volumetric flask with water (H2O). ...

  • Optimal finite element modelling for modal analysis of liquid storage circular tanks

    Model analysis of liquid storage vertical tanks is a complex task due to fluid–structure–soil interaction. Analysis of tanks subjected to earthquake excitations using finite element modelling (FEM) has become a preferred technique. The FEM is validated by comparing its results with experimental and theoretical results in the literature. However, most finite element studies in literature do not ...

  • Theoretical analysis and finite element modelling of composite ferrocement–concrete beams

    Composite ferrocement–concrete beams have been introduced in the literature as a viable alternative for the conventional reinforced concrete beams. This paper presents a proposed theoretical and a three–dimensional non–linear finite element models for simulating and analysis of composite ferrocement–concrete system. The theoretical and the finite element models were used to analyse ten composite ...

  • Elemental composition analysis in lichens transplanted to the western region of Catamarca, Argentina

    Thalli of the lichen Parmotrema austrosinense were collected in their natural non-polluted habitat and transplanted to 18 monitoring sites within an area of the western region of Catamarca province (Argentina) where fruticose lichens are absent. This region is going through a reactivation phase, owing to large-scale mining development and agricultural expansion. The concentrations of 25 elements ...

  • Firmness evaluation of melon using its vibration characteristic and finite element analysis

    Analysis of the vibration responses of a fruit has been suggested as a non-destructive measure of its elastic properties (firmness). In this study, 'Huang gua' melons were excited using three types of balls (wooden, steel and rubber) and the vibration was detected by an accelerometer. The modulus of elasticity of the inner, middle and outer portions of melon flesh were determined using flat plate ...

  • Finite element analysis of buried continuous pipeline subjected to fault motion

    Pipeline generally extends over long distances traversing through wide variety of different soils, geological conditions and regions with different seismicity. Most analytical models developed in the past for pipeline fault crossing are of limited usage as models developed were useful only for strike slip fault. Incorporating the large geometric changes in analytical study is a tricky task; ...
