The document is about the analysis method of electroless plating bath, using capillary electrophoresis technology, can detect metal ions and inorganic anions
This document details a method for monitoring electroless plating baths, specifically for non-metals like ceramics and plastics. It explains how capillary electrophoresis (CE) with indirect UV detection can effectively monitor metal cations, reducing agents, organic acids, and inorganic anions present in these bath solutions. The text highlights the advantages of CE over ion chromatography for analyzing complex bath compositions with minor sample preparation.
| Detection limit | 1-2 ppm |
|---|---|
| Linearity range | 10-100 ppm |
| Repeatability (migration times) | < 0.1 % RSD |
| Repeatability (peak area) | < 4.5 % RSD |
| Capillary length | 80.5 cm total |
| Operating voltage | -25 kV |
| Operating temperature | 20°C |
The analysis uses the Agilent Plating Bath Analysis Kit (Agilent part number 5064-8228).
Buffer vials should be replaced after 10 runs when using 2 mL-vials and after 5 runs when using 1 mL-vials.
Sample preparation consisted simply of dilution with water.
