Determination of acrylonitrile in materials in contact with foodstuffs.
Monitoring of the content of free acrylonitrile in plastics used for the preparation of viands is necessary due to its negative effect on human health. A content of 20 ppb is the maximal value of free acrylonitrile in such samples. In this case, head-space gas chromatography is most favourable analytical method when combined with the standard addition method together with a mass-spectrometry de...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولMicrobiological determination of methionine in proteins and foodstuffs.
Kuiken and coworkers (1) reported that methionine is not essential for the growth of Lactobacillue arabinosus 17-5. Later, Hegsted (2), working with the same organism, found that growth failed when methionine was not present in the medium. He called att,ention to the apparent discrepancy in the results obtained in the two laboratories and stated that it was probably due to the use of different ...
متن کاملDetermination of 226Ra and 228Ra concentrations in foodstuffs consumed by inhabitants of Tehran city of Iran
ABSTRACTBackground : The presence of primordial radionuclide in human habitats has always been a source of prolonged exposure. Measurement of naturally occurring radionuclides in the environment can be used as baseline to evaluate the impact of non-nuclear activities and also routine releases from nuclear installations. Materials and methods: A total of 56 samples from 18 different foodstuf...
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
