LABORATORY AND PLANT: LABORATORY PROBLEMS IN INDUSTRIAL CHEMISTRY

Laboratory hemostasis: milestones in Clinical Chemistry and Laboratory Medicine.

Hemostasis is a delicate, dynamic and intricate system, in which pro- and anti-coagulant forces cooperate for either maintaining blood fluidity under normal conditions, or else will prompt blood clot generation to limit the bleeding when the integrity of blood vessels is jeopardized. Excessive prevalence of anticoagulant forces leads to hemorrhage, whereas excessive activation of procoagulant f...

Methodology in diagnostic laboratory test research in clinical chemistry and clinical chemistry and laboratory medicine.

BACKGROUND The application of epidemiologic principles to clinical diagnosis has been less developed than in other clinical areas. Knowledge of the main flaws affecting diagnostic laboratory test research is the first step for improving its quality. We assessed the methodologic aspects of articles on laboratory tests. METHODS We included articles that estimated indexes of diagnostic accuracy ...

Organic Chemistry I Laboratory

For many years the dehydration of 2-methylcyclohexanol to a mixture of alkenes has been carried out in college organic chemistry labs to demonstrate the application of Zaitzev’s rule and the occurrence of the E1 reaction mechanism in alcohol dehydration reactions. In 1994 David Todd, then a chemistry professor at Pomona College, was distilling the product alkenes out of the reaction mixture whe...

Organic Chemistry I Laboratory

The problem you need to solve is to determine the identity of the individual components from your mixture. You will use several different techniques today and compare your experimental results to those of known standards. From this data you should be able to identify all of the components of your original mixture. Keep careful records of your observations and your interpretation of spectra so t...
