| Abstract: | Trigonelline can be determined in green and roasted coffee extracts by a ion chromatographic method on a single column filled
with polybutadiene-maleic acid (PBDMA) coated on silicia, 2 mmol/L aqueous HCl (pH 3) as eluent and UV detection at 254 nm.
The merits of the new method are investigated.
