Repeatability And Reproducibility

An analytical method for determination of the biogenic amines: tryptamine, putrescine  histamine, phenylethylamine, tyramine, cadaverine, spermidine and spermine in red and white wines using pre-column derivatization with dansyl chloride (DnsCl) and reversed phase-high performance liquid chromatography with diode array detector (RP-HPLC-DAD) was developed and optimized. Concentration of DnsCl, pH, time of reaction and evaporation under nitrogen were tested and optimized. Best recoveries, ranging from 72 to 102 % were obtained for all analyzed amines applying derivatization with 10 mg/mL of DnsCl for 1 h at 60 oC and pH 9. The developed method showed excellent linearity with R2>0.99 for all tested amines. The accuracy was checked with the standard addition method showing satisfactory recovery, good repeatability and reproducibility. The optimized and validated method was applied for analysis of white and red wines from Macedonian origin, observing higher total amounts of biogenic amines in red wines.

A simple , specific, accurate and precise RP-HPLC method was developed for determination of Irbesartan (IRB) in pharmaceutical dosage forms in tablets products and sachet using symmetry (L 1 ) column at 30°C . The signal was detected at 225 nm. A mobile phase dissolve 0.5 g of buffer potassium phosphate in 100 ml distilled water and adjust pH 2.7 , methanol and acetonitrile at ratio (40 :30 :30 ) . and flow rate 1.2ml/min -1 at pH=7.2 a mobile phase The percent recovery was detected 101 % and the linearity of concentration was 10-50 µg.ml -1 and supported this method by using (FT.I.R.) spectrum method for organic spectrophotometer to prove the chemical structure of this drug and some physical properties . we are obtained the result is identical of other literature . The proposed method was applied successfully for determination of the IRB in tablets products.
