• New Test To Detect Triclosan in Water
  environmental monitoring of this widely used antibacterial agent in rivers, wells, and other bodies of water. Such is the hope of a team of Agricultural Research Service (ARS) and Abraxis, Inc., scientists who compared the new triclosan test, called "magnetic particle enzyme immunoassay," to the more...
• Understanding Variability, its Sources and its Impact on the Pharma Supply Chain
  By Fernando Portes, Principal Project Manager, Best Project Management The option to increase C through reduction in the observed variability is far more complicated, lengthy and expensive. Assay variability can be calculated from the assay validation reports. Observed variance can be calculated...
• A Review of Analytical Methodologies in PM Analysis
  An attempt has been made to review a broad range of methodology currently in use at labs providing services to the precious metals industry. Preference of a particular technique may vary from one lab to another. Very often this choice is based upon the range of equipment available for assay...
• Medical Device Link .
  Testing urine for drugs of abuse An overview of testing methods demonstrates opportunities for assay manufacturers in on-site workplace testing. In vitro testing for drugs of abuse has clinical and forensic applications. In clinical toxicology, drug testing is performed when individuals exhibit...
• A Probabilistic Approach to Modeling Microstructural Variability and Fatigue Behavior in ASTM F562 Medical Grade Wire (.pdf)
  Several previous studies have demonstrated the importance of constituent inclusion particle distributions on variability in observed fatigue lifetimes. Such models have often concentrated on crack growth behavior in standard test specimens such as single edge notch tension (SENT) geometries...
• Ending the Paper Chase
  , adoption of ELNs deeper into manufacturing requires that a few companies lead the way. AstraZeneca s Westborough, Mass. manufacturing site has assumed the role of test facility for the company s electronic data systems evaluations in analytical labs. Recently-installed products include a LIMS...
• Assure Batch Uniformity for Freeze-Dried Products
  lyophilization, most notably, the heat transfer required to freeze and then sublimate ice in the product. Temperature must be closely controlled from the time that product is loaded onto the lyophilizer shelves until it is removed after stoppering. A comprehensive OQ study must therefore test: Each...
• New Ways To Monitor Toxins
  for an existing enzyme-linked immunosorbent assay. Known as an ELISA test, it uses the new antibody to selectively bind to aflatoxin, thereby improving the accuracy in detecting the toxin. Maragos explains, "If there is no toxin for the antibody to bind with, we see a deep orange color in the test solution...
• New Detection Methods Improve Food Safety
  them out of complex mixtures of food. Once extracted, the bacteria can be more easily detected. Gehring is also developing a luminescence-based method coupled with an ELISA (enzyme-linked immunosorbent assay) to detect and confirm E. coli O157:H7. An ELISA is a sensitive laboratory test that uses...
