WebPhosphate buffer (PB) pH 6.0 preparation method. By mixing solutions of Na 2 HPO 4 ·2H 2 O (6.2 ml, 0.2 M) and NaH 2 PO 4 ·2H 2 O (43.8 ml, 0.2 M) in deionized water, a stock solution of 0.1 M PB (pH 6.0) was created. The pH of the PB was adjusted at 6.0 using either concentrated HCl or KOH. 2.2. GSH sensing using UV–vis spectrophotometer WebMar 16, 2024 · The presence of phosphate ion decreases the sensitivity of measurements of calcium. Excess strontium or lanthanum ions will complex with the phosphate and improve the sensitivity of the calcium measurement. Another potential problem that can occur in flames and plasmas is to have too high a concentration of the analyte metal exist in an …
