Journal of chromatography. A, 1216(36), 6387-6393 (2009-08-01)

A new HPLC method for determining biogenic amines in wines is developed. This method is based on pre-column amine derivatization, further separation of derivatives and on-line hyphenation of HPLC to atmospheric pressure chemical ionization mass spectrometry (APCI-MS). Biogenic amines have

Spectrophotometric method for the determination of paracetamol and phenacetin.

P Nagaraja et al.

Journal of pharmaceutical and biomedical analysis, 17(3), 501-506 (1998-07-10)

A rapid, sensitive and simple spectrophotometric method is proposed for the determination of hydrolysis products of paracetamol (PRL) and phenacetin (PHN) with sodium 1,2-naphthoquinone-4-sulphonate and cetyltrimethyl ammonium bromide (CTA) in alkaline medium. The absorbances are measured at 570 and 500

A kinetic spectrophotometric method for simultaneous determination of glycine and lysine by artificial neural networks.

Masoumeh Hasani et al.

Analytical biochemistry, 365(1), 74-81 (2007-03-22)

A spectrophotometric method for simultaneous analysis of glycine and lysine is proposed by application of neural networks on the spectral kinetic data. The method is based on the reaction of glycine and lysine with 1,2-naphthoquinone-4-sulfonate (NQS) in slightly basic medium.
