Quantitative Estimation of Efavirenz by High Performance Thin Layer Chromatography

A simple, accurate, and precise HPTLC method has been developed and validated for the estimation of efavirenz from bulk drug and capsule formulations. The separation was achieved on TLC plates using an appropriate solvent system. The spots so developed were densometrically scanned at 247 nm. The linearity of the method was found to be within the concentration range of 1-40 μg/ml. The validation...

Uncertainty in quantitative thin-layer chromatography.

Globalization forces analysts to demand extended control of variability in analytical measurements. A calculation procedure named the "error budget model" following recommendations proposed more than 20 years ago by the Bureau International des Poids et Mesures is established as a rule for evaluating and expressing the measurement uncertainty across a broad spectrum of measurements. This metrol...
