Capillary batch injection analysis (CBIA) is applied to the determination of ascorbic acid in nanolitre samples at neutral pH. It is demonstrated that pulsed amperometric detection is superior to constantpotential amperometric detection with respect to signal stability. The calibration plot is linea
After the mixed chlorides of potassium and sodium have been isolated, potassium is determined by the pcrchloratc or chloroplatinate method and sodium by diffcrencc. In their work on the analysis of silicates and of rcfrnctories, MILLEH AND TRAVI& and HASLAM ANI) BEELEY~ showed that the cumbersome se
