“…To determine polar compounds various analytical methods exists specifically for INH in literature [6]. Various other methods also have been described for determination and quantification of INH, such as H-point standard addition method [7], selective adsorption using a piezoelectric sensor [8], voltammetric method [9], amperometric method [10], chromatographic methods [11][12][13][14] (HPLC, GC and HPTLC), titrimetric methods [15], and chemiluminescence [16]. In addition, several (HPLC) methods for the simultaneous determination of rifampicin (RIF), INH, and pyrazinamide (PZA) in a fixed-dose combination [17] simultaneous analysis of RIF, INH and PZA in 0.1 M hydrochloric acid dissolution medium and in simulated gastric fluid [18], quantitative determination of INH in plasma, brain, liver and kidney samples and in solid lipid nanoparticles [19].…”

“…By plotting the analytical signals versus added analytical concentration, two straight lines are obtained that have a common point H with coordinates (C H , A H ); C H is the unknown analyte concentration and the A H is the analytical signal due to the interferent species .The HPSAM has been used, eliminating blank bias error due to the use of an absorbent blank [15][16] . HPSAM has also been applied to liquid chromatography 17 , analysis kinetic data analysis [18][19][20][21] with an additional variant time and in metal speciation [22][23][24] .…”

“…Dentre eles podemos destacar os métodos cromatográficos [3,4] e espectrofotométricos [5,6], envolvendo a determinação indireta de hidrazina. Quimiluninescência (CL) acoplada à técnica de injeção de fluxo também foi descrita na literatura [7] para determinação de hidrazina em amostras de água com detecção limite de 2 x 10 -7 mol L -1 .…”
