USA VIROLOGY LABORATORY NEEDED FOR VIRUCIDAL EFFICACY TESTING AGAINST PEDV (Porcine epidemic diarrhea vírus) AND DILUTION TEST AGAINST APP ( Actinobacillus Pleuronemoniae). PLEASE LET ME KNOW THE COST AS WELL AS THE TIME REQUIRED FROM SUBMISSION TO FINAL REPORT.
Small chemical company that imports research chemicals needs laboratory to have incoming shipments tested for purity and to validate that it is the correct compound. Proton NMR may be sufficient in most cases. Since H-NMR is not the best for determining purity then it may also require quantification by NMR or LCMS
Australia analytical chemistry laboratory needed for agrochemical analysis of five batches of an active used in agrochemicals. The active technical grade constituent is Linuron, and the tests to be performed would be as follows:
1) Assay: this would include assay method development and validation.
- Validation parameters: specificity, precision, linearity, accuracy and range.
2) Impurities: This would include:
- Identification of any impurities above 1.0% levels (by area normalization) through PDA-LC/MS, GC/MS or any other suitable technique.
- Validation for all specified impurities and active at low levels (surrogate for unknown/unspecified impurities) . Validation parameters: specificity, precision, linearity, accuracy, range, LOD and LOQ.
3) Sulphated Ash
4) Water Content: by Karl Fischer
5) Residual solvents: by Headspace GC, using appropriate validated methodology.
For the assay and impurities, I would suggest HPLC as the substance is not very volatile, and may decompose upon heating. The water content and residual solvent test may be substituted by loss on drying.
Analytical Chemistry Laboratory needed for organic salt compound testing of organic compound is presented in the form of a hydrochloride salt.

assess the androgenic activity, in a quantitative fashion, of a single steriod with the trivial name tetrahydrogestrinone(THG) in a pilot scale study. Either an aquatic organism model or rodent model would appear adequate to provide the information desired but other potential testing types will be considered such as in-vitro receptor binding studies. The study should compare the relative androgenicity of THG to a reference compound such as testosterone
