The aim of the International Measurement Evaluation Programme (IMEP) is to give an objective picture of state-of-the-practice analytical measurements by comparing them to a reference value obtained by a primary method of measurement. The referenceval

All analytical techniques depend on the use of calibration chemicals to relate analyte concentration to an instrumental parameter. A fundamental component in the preparation of calibration solutions is the weighing of a pure chemical or metal before

The sub-boiling method of acid purification for low trace element blank has now been in use for about 20 years. However, to achieve commercially useful yields, distillates must be produced at {approx} 25-100 L/day. Aspects of still design that includ
