6 Electroplating Bath VA
6.1 Electroplating Bath VA – Introduction
The 797 VA Computrace has two special modes for electroplating
bath analysis: CVS (Cyclic Voltammetric Stripping) and CPVS (Cy-
clic Pulse Voltammetric Stripping). Working with these two modes,
you have to consider that some settings and options differ from
working with the other modes.
6.2 Calibration techniques with CVS and CPVS
With CVS and CPVS, 8 Calibration techniques are available:
• Standard addition plating bath
• LAT Record intercept value
• LAT Standard addition for brighteners
• MLAT Standard addition for brighteners
• DT Suppressors with calibration curve
• DT Record calibration curve
• RC Sample with response curve
• RC Record response curve
Standard addition plating bath
“Standard addition plating bath” is a Calibration technique for CVS
and CPVS. It is mainly used to develop methods:
• Optimize addition volumes and concentrations (e.g. to get
“Addition ratio” after 5 to 20 additions for “DT Record cali-
bration curve” and “DT Suppressors with calibration curve”)
• Optimize dilution with "Intercept solution" for “MLAT”
• Check linear range of standard addition (with “LAT” and
“MLAT”)
