WebNov 1, 2009 · Ammonium hydrogen carbonate has been described as an excellent buffer for the analysis of basic drugs by HPLC–MS (10). In fact, this mixed buffer presents a good buffer capacity in a relatively wide pH range, because the buffer capacity of ammonium–ammonia species is added up to the one corresponding to hydrogen … WebThis method measures bicarbonate (HCO 3- ), carbonate (CO 32-) and alkalinity levels in water. Quantitation is by titration with 0.025 N H 2 SO 4. The method has a routine detection limit of 0.1 meq/L but is capable of a method detection limit for alkalinity of 0.04 meq/L (2 mg CaCO 3 /L) if requested by client. Sample must be refrigerated.
