Collaborative Study of Clopidol in Chicken Tissues and Eggs, Using Gas-Liquid Chromatography

Determination of clopidol residues in chicken tissues by liquid chromatography: collaborative study.

Eighteen laboratories participated in a collaborative study on the determination of clopidol residues in chicken muscle tissues by liquid chromatography. Of these, results from 16 laboratories which rigorously followed the method were subjected to statistical analysis. The method performance was assessed by all participants using 14 samples of chicken muscle fortified at concentrations ranging ...

Determination of residual clopidol in chicken muscle by capillary gas chromatography-negative chemical ionization-mass spectrometry.

A selective, sensitive gas chromatography-mass spectrometry (GC-MS) method with negative chemical ionization (NCI) was developed for the detection and quantification of clopidol in chicken muscle. Chicken muscle samples were extracted with acetonitrile and concentrated to dryness; the residue was redissolved in ethyl acetate and applied to an Alumina B cartridge for cleanup. The residue was der...

hazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures

شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...

Determination of tilmicosin residues in chicken, cattle, swine, and sheep tissues by liquid chromatography.

A method was developed and validated for determination and quantitation of tilmicosin residues in swine, cattle, and sheep edible tissues, as well as chicken fat, skin, and muscle over a concentration range of 0.025 microg/g-20 microg/g. For chicken kidney and liver, the method was validated over a range of 0.060 microg/g-20 microg/g. The tissue sample was extracted with methanol and a C18 cart...
