8.6 Analyze Electroplating Bath Solutions
Introduction
The 797 VA Computrace can perform electroplating bath analysis.
Two modes are especially designed for Electroplating Bath VA: CVS
(Cyclic Voltammetric Stripping) and CPVS (Cyclic Pulse Voltammet-
ric Stripping).
With these two modes, 8 different Calibration techniques can be
chosen:
For method optimization:
“Standard addition plating bath” (this Calibration
technique is used to develop and optimize methods)
For Brightener analyzing:
“MLAT Standard addition for brighteners” (Modi-
fied Linear Approximation Technique)
“LAT Standard addition for brighteners” (Linear
Approximation Technique)
"LAT Record intercept value” (is used to record the
"Intercept value")
For Suppressor analyzing ("Dilution Titration Technique"):
"Dilution Titration Technique"
“DT Record calibration curve“ (used to record the
calibration curve)
