Stable Isotope Analysis Techniques: Powerful Analytical Tools for Various Fields
What Are Stable Isotope Techniques? A class of atoms with the same number of protons but different numbers of neutrons in the nucleus is called isotopes, which can be divided into stable isotopes and radioactive isotopes. The nucleus of a radioactive isotope is unstable, and it decays into another isotope by spontaneously emitting particles. Isotopes that are not radioactive are called stable ...

Fume Hood vs Flow Hood
Though hazardous vapors and gases are dangerous, many professionals handle hazardous these materials every day. Fume hoods and flow hoods exist to protect personnel from exposure to harmful substances. However, they are not the same device. In fact, depending on the type of work being performed, you will have to decide whether a fume hood or flow hood may be most appropriate.Although both of ...

Spectrally accurate quantitative analysis of isotope-labeled compounds
Abstract Calculated profile mode mass spectrometry (MS) data are fitted to lineshape-calibrated liquid chromatography LC/MS data using a Multiple Linear Regression (MLR) model to quantitate the relative concentrations of stable or radiolabeled compound mixtures. This alternative approach significantly improves the precision and accuracy over existing MS methods while providing the much-needed ...

Prj 9121 - Deactivation of radioactive water - Case Study
Although radioactive isotopes are engaged for many applications (i.e. medicine, metallurgy, etc.), the major sources of soil and water contamination with radioactive substances are connected to nuclear waste processing and to uranium mining operations. One of the principal carcinogens is plutonium and any soil or water contaminated by plutonium should be carefully removed and disposed in ...

Air Sampling During NPP Accident
There has been considerable interest recently generated regarding emergency air sampling protocols as a result of the Fukushima accident in Japan. A major concern involving air sampling requirements is the accurate determination of gaseous-radioactive iodine species emitted from the NPP to the environment as a result of an accident. During normal NPP operation gaseous radioactive iodine ...

Better tools for fast and convenient Patulin analysis
Analytical Standards and New SupelMIP SPE Cartridges The mycotoxin patulin is often found in rotten apples. It is mostly produced by Aspergillus, Penicillium and Byssochlamys and shows a variety of short-term and long-term effects in animal studies, ranging from gastrointestinal problems and neurotoxicity to genotoxicity and teratogenicity. Therefore, many countries set limits for patulin ...

Prediction of solid‐solution partitioning coefficients (Kd) for cationic metals in soils using mid‐infrared diffuse reflectance spectroscopy
Partial least squares regression (PLSR) models, using mid‐infrared (MIR) diffuse reflectance Fourier transformed (DRIFT) spectra, were used to predict distribution coefficient (Kd) values for selected added soluble metal cations (Ag+, Co2+, Cu2+, Mn2+, Ni2+, Pb2+, Sn4+, and Zn2+) in 4813 soils of the Geochemical Mapping of Agricultural Soils (GEMAS) program. For the development of the PLSR ...

Non–destructive radiotracer technique in characterisation of nuclear grade anion exchange resins Tulsion A–30 and Dowex 550A LC
The present study deals with the application of non–destructive radio isotopic tracer technique to evaluate the performance of nuclear grade resins Tulsion A–30 and Dowex 550A LC. The evaluation was made by testing the performance of the two resins during iodide and bromide ion–isotopic exchange reactions. It was observed that at a constant temperature of 30°C, as the concentration of labelled ...

Pb–210 irradiation dose estimation for inhabitants living in high natural background areas on Pernambuco/Brazil
This work was designed to: (a) determine 210Pb concentration in human urine samples of inhabitants of two regions with high natural radiation in the state of Pernambuco - Brazil; (b) estimate radiation dose in bones as a result of this radionuclide incorporation. For this, urine samples of healthy and non–smoker subjects were studied. Pb–210 was separated by ion–exchange resin technique followed ...

Establishment of a radioactive contamination index in seawater from the Gulf and Pacific coasts in Mexico
This paper intends to establish one radioactive contamination index in seawater based on the relation A1/A2, where A1 is the radioactivity due to the contaminant radioisotope 137Cs and A2 is the radioactivity due to the natural radioisotope 40K, both expressed either as Bq/l in seawater or Bq/g in sea salt. At a second step, the same volumes of marine sediments were detected, but in this case ...
