Simple, automated SPE procedure combined with fast LC-MS/MS chromatographic separation resulted in obtaining high-throughput LC-MS/MS method for determination of indapamide in serum. The SPE procedure was performed on polymeric mixed-mode sorbent and the analytes were quantitated using electrospray ionization in positive mode. The recovery of indapamide and internal standard were 89.25- 90.36% and 79.10%, respectively. Experimentally it was confirmed that the matrix effect had a negligible effect of ionization efficiency. The validation data showed that the proposed method provides accurate and reproducible results in range of 0.50-50 ng/mL. In addition, a comparison was made between the method for determination of indapamide in serum and in blood (develop in our previously work) regarding the extraction procedure and matrix effect.

Extracting Solvent

The procedure for the determination of carbamate pesticides in soil was optimized. The following factors affecting the final results were investigated: extracting solvent, extraction procedure, extract purification procedure, and soil type. Triple extraction with acetone and purification of the extract on a two-stage purification column containing an activated carbon-silica gel 1+1 mixture were found optimal. The extracts after treatment were analyzed by RP-HPLC with UV detection. The method developed allows carbamate pesticides in soil to be determined at concentrations in excess of 30 μg kg-1.
