Gas chromatography with flame ionization detection for determination of additives in an electrolytic Zn bath

Quantification of benzoic acid in beverages: the evaluation and validation of direct measurement techniques using mass spectrometry

“…It is useful in inhibiting the growth of fungi and pathogenic bacterial in food. 9 Most of the analytical methods reported for the determination of benzoic acid in orange juice employ high performance liquid chromatography (HPLC), [10][11][12] but it is also possible to nd methods, which use gas chromatography equipped with a ame ionization detector (GC-FID) 13,14 and gas chromatography coupled to mass spectrometry (GC-MS). 15 Modern analytical chemistry requires that analyses are performed with minimal sample preparation and that the instruments are in use for the shortest time possible to allow high throughput monitoring of a different number of analytes.…”

Complexing capacity of electroplating rinsing baths—a twist to the resolution of two ligand families of similar strength

“…Benzylideneacetone (BDA), benzoic acid (BA), and polyethylene glycol 400 (PEG400) are easily found among the additives used in zinc baths (Barriola et al 2012). Many of these additives can act as metal ligands affecting the efficiency of the recovery and/or wastewater treatment processes.…”
