A simple and inexpensive method was developed with gas chromatographic method with FID detection for determination of telmisartan residual solvents (methanol, 1-Butanol, tetrahydrofuran and toluene). The chromatographic separations were achieved on J&W B-624 30m, 0.53mm, film thickness 3.0 μm column, helium as carrier gas with flow rate 4.2 mL/min, Injector Temperature is 220°C, detector temperature is 250°C, Head Space Bath Temperature is 90°C, transfer line temperature is 210°C were chosen. Three residual solvents were eluted within 20 minutes. The method was successfully validated by establishing System Suitability, Specificity, Linearity, Accuracy, limit of detection and Limit of quantification.
