i need to determine low ppm levels of some small acid (very low pka) in commercial sugar. Sorry, I can't give more info.
at that ppm level i need to use ELS or MS/MS for detection, which i don't have. So, the alternative is derivatization but the sugar is interfering.
do you know how can I remove the matrix (sugar) from the solution?
i appreciate your advice
thanks
