INTEGRATED RETENTION SPECTROPHOTOMETRIC DETECTION METHOD FOR THE DETERMINATION OF FORMALDEHYDE
(MARCEL DEKKER INC, 1992)
An integrated-sensor method for the determination of formaldehyde based on retention of the reaction product of the analyte with p-rosaniline and sulfite in a flow-cell packed with Dowex 1-X-8 anion exchange resin was ...
Integrated retention/spectrophotometric detection method for the determination of formaldehyde
(1992)
An integrated-sensor method for the determination of formaldehyde based on retention of the reaction product of the analyte with p-rosaniline and sulfite in a flow-cell packed with Dowex 1-X-8 anion exchange resin was ...
Electrochemical and spectrophotometric methods for polyphenol and ascorbic acid determination in fruit and vegetable extracts
(University of Zagreb, 2020-04)
Research background. Fresh-cut fruits and vegetables are considered sources of antioxidant compounds. However, their shelf life is limited due to nutritional, quality and safety deterioration. Therefore, in recent decades, ...
Spectrophotometric detection of arsenic using flow-injection hydride generation following sorbent extraction preconcentration
(Elsevier B.V., 1999-12-06)
An automated system with a C-18 bonded silica gel packed minicolumn is proposed for spectrophotometric detection of arsenic using flow-injection hydride generation following sorbent extraction preconcentration. Complexes ...
