Trace anion detection in liquid samples

摘要: The present invention provides a method of detecting trace anions in solutions at parts per billion (ppb) concentration level or less using existing anion detection technology, by employing novel sample preparation conducted prior to injection into unit. includes the steps of: adding precipitant least portion solution; evaporating solution, whereby anion-rich solution is formed; and ppb level. As such, any unit designed for measuring anions, known those skilled art, can be used without modification. This results cost time effective also system effectuating invention.
