Performing Annual Maintenance Tasks
Before calibrating the Analyzer, perform annual maintenance tasks as appropriate,
such as replacing the sample pump heads, UV lamp, and resin cartridge. In particular,
if the calibration coincides with the Analyzer’s annual maintenance, first replace the
resin cartridge before proceeding; for more information, see
.
Handling Standards
Because of the prevalence of organic carbon contaminants, sample preparation and
control is extremely delicate. Special handling of the standard solutions is required.
Store standards at approximately 5 °C (±4 °), away from light, in a box or solid-door
refrigerator. Warm standards to ambient temperature prior to starting analysis. Avoid
touching the top of the vials to protect against introducing foreign particles, TOC, and
conductivity.
