| Significance and Use | ||
|
It is important to monitor the anion concentrations and anion contaminants in electrocoat baths. Wet chemical methods are long, tedious, and of questionable accuracy in the ppm range. Ion chromatography offers a fast, convenient and accurate alternative. Since IC analysis of electrocoat bath samples is difficult, the permeates are often analyzed for contaminants. This guide addresses some important considerations for such analyses. |
||
| 1. Scope | ||
|
1.1 This guide is used for the determination of nitrate anion in electrocoat bath permeate by use of chemically suppressed and non-suppressed ion chromatography (IC). 1.2 Other anions, with the exception of phosphate, may be determined in electrocoat bath permeates by use of this guide. 1.3 It is the responsibility of the user of this guide to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
