Area
Peak area between peak curve and calculated
baseline.
Derivative
Difference between positive an negative maximum
of the first derivative of the voltammogram.
Coulometric
Charge transmitted during the peak.
Smooth factor [ 1...6 ; 4 ]
Smoothing power of the Savitzky/Golay smooth-
ing of the baseline (1 = minimum smoothing, 6 =
maximum smoothing) (see Smoothing and differ-
entiation, section 5.8).
Eliminate spikes
Eliminates spikes to smooth the signal.
Reverse sweep [ on, off ; off ]
Enable peak evaluation of the reverse sweep of
cyclic sweeps (not available with CPVS).
LAT Standard addition for brighteners
Linear Approximation Technique (“LAT Standard addition for
brighteners”) is a Calibration technique for CVS and CPVS. It is
mainly used to analyze Brighteners in electroplating baths. It is cho-
sen, if the difference between Q(“Intercept solution” + “Bath solu-
tion”) and Q(only “Intercept solution”) is too small to use “MLAT
Standard addition for brighteners”.
The "Intercept value" needed for the calculation can be recorded
and adopted automatically with the Calibration technique "LAT Re-
cord intercept value".
Note: If possible, “MLAT” should be the preferred
Calibration tech-
nique for Brightener determination. With “MLAT”, “Intercept solu-
tion” and “Bath solution” are measured successively in the same
method run, what minimizes fluctuations caused by solution ex-
change and time displacement of the measurements.
Note: A determined "Intercept value" is only adopted automati-
cally if the checkbox Save calibration curves additionally without
date and time
on the General tab of the GENERAL SETTINGS win-
dow is checked.
Determination tab with Calibration technique “LAT”
The Determination tab of the EDIT WORKING METHOD PARAME-
TERS
window contains general specifications for performing the
determination. The parameters displayed depend on the selected
Calibration technique and measurement Technique. With “LAT
