In the electronics industry, ionic contamination in the range of parts per trillion (ppt, ng/L) to parts per billion (ppb) concentrations is a major concern, causing corrosion-related failures in production and final product. The AutoPrep technique uses 1000-fold difference of sample loading with preconcentration to achieve trace ion determinations: large loop for samples and a small loop for standards. This is the AutoPrep template for ng/L (ppt) calibrations using individual ppb standards onto a 20 µL small loop as compared to the sample on a 20 mL large loop.

The AutoPrep technique uses 1000-fold difference of sample loading with preconcentration to achieve trace ion determinations: large loop for samples and a small loop for standards. This is the AutoPrep template for ug/L (ppb) to ng/L (ppt) calibrations using individual ppb standards onto a 10 µL small loop as compared to the sample on a 10 mL large loop.

The AutoPrep technique uses 1000-fold difference of sample loading with preconcentration to achieve trace ion determinations: large loop for samples and a small loop for standards. This is the AutoPrep template for ng/L (ppt) calibrations using incremental injections of a ppb standard onto a 20 µL small loop as compared to the sample on a 20 mL large loop.

In the electronics industry, ionic contamination, in the range of parts per trillion (ppt, ng/L) to parts per billion (ppb, μg/L) concentrations, is a major concern. This contamination can cause corrosion-related failures. Three techniques will be discussed: 1) Large volume direct injection, 2) Large volume with preconcentration, and 3) Thermo Scientific™ Dionex™ AutoPrep™ method using large volume preconcentration for samples, small volume preconcentration for standards, and an inline water purifier to create a closed loop system. General precautions and tips are thoroughly discussed.
