In this chapter the commonly used DBD measurement methods applied for the different material types, including

This group of techniques is traditionally referenced as Quality Assurance – Quality Control system and often called by acronym ‘QAQC’. In general, QAQC procedures consist of monitoring accuracy and precision of analytical results, controlling the s

Twinned holes can also be used for special tasks such as correcting earlier data that are recognized to be biased..Successful implementation of the twinned-holes technique requires thorough planning. Experience suggests that good
