摘要:Abstract(#br)A sequential injection (SI) system equipped with in-line solid phase extraction column and in-line soil mini-column is proposed for determination of zinc and copper in soil leachates. The spectrophotometric determination (560 nm) is based on the reaction of both...

摘要:Abstract(#br)A novel method for correction of unknown unspecific (additive) interferences was developed in sequential injection analysis (SIA) using a Lab on Valve module (LOV) with spectrophotometric detection. The method implements a novel idea to calibrate by the standard...

摘要:Abstract(#br)Generalized calibration strategy (GCS) is one of the innovative approaches aimed at verification and improvement of accuracy of analytical determinations. It combines in a single procedure the interpolative and the extrapolative calibration approaches along with step...

摘要:Abstract(#br)A novel automatic vigorous-injection assisted dispersive liquid–liquid microextraction procedure based on the use of a modified single-valve sequential injection manifold (SV-SIA) was developed and applied for determination of boron in water samples.(#br)The maj...

摘要:Abstract(#br)Novel simple and fully automated procedure – the stepwise injection analysis (SWIA) coupled with the generalized calibration method (GCM) – has been suggested for the automation of spectrophotometric analysis of complex sample matrices. The performance of the su...

摘要:Abstract(#br)Polypyrrole nanowires (PPyNWs) were fabricated and examined as a structural component of amperometric biosensor matrix. An enzyme, tyrosinase (TYR), was immobilized onto PPyNWs using glutaraldehyde (GA). Matrix composite morphology was investigated using scanning ele...

摘要:Abstract(#br)Novel approach to calibration by the complementary dilution method (CDM) is presented. The CDM integrates in a single procedure the set of standards and the standard addition calibration methods. The approach is implemented with the use of the fully automated monoseg...

摘要:Abstract(#br)An automatic sequential injection system, combining monosegmented flow analysis, sequential injection analysis and sequential injection titration is proposed for acidity determination. The system enables controllable sample dilution and generation of standards of req...
