Analytical methods for determination of neat and microencapsulated trichloroethylene in dosing vehicles and whole blood.

Gas chromatographic methodologies were developed for the analysis of microencapsulated trichloroethylene (TRI) in corn oil and feed dosage formulations as well as neat TRI in corn oil and whole blood. Recovery, precision, linearity, and the appropriateness of a linear regression model were evaluated for each method. In all cases recovery was greater than 96% and linearity of the standard curves was confirmed. Good precision and chromatographic resolution were obtained for all samples analyzed.
