Audience and purpose
This guide is intended for personnel who install, operate, and maintain the Waters
2432 Conductivity Detector.
Intended use of the detector
The Waters 2432 Conductivity Detector is intended to measure the ionic strength of
a solution with a pair of inert electrodes. The resulting chromatograms measure
concentrations of anions and cations. Typical applications are in water chemistry,
sugar and salt content in food, and water analysis for pollution. The Waters 2432
Conductivity Detector is not intended for clinical applications, but rather for use as a
general laboratory module.
Calibrating
To calibrate LC systems, follow acceptable calibration methods using at least five
standards to generate a standard curve. The concentration range for standards must
include the entire range of QC samples, typical specimens, and atypical specimens.
Quality control
Routinely run three QC samples that represent subnormal, normal, and above-
normal levels of a compound. If sample trays are the same or very similar, vary the
location of the QC samples in the trays. Ensure that QC sample results fall within an
acceptable range, and evaluate precision from day to day and run to run. Data
collected when QC samples are out of range might not be valid. Do not report these
data until you are certain that the instrument performs satisfactorily.
