TOC & Conductivity Analyzers

TOC analyzers use methods such as high-temperature combustion or UV and persulfate oxidation, each suited to different sample types. Combustion handles higher carbon loads while oxidation methods suit clean pharmaceutical water. Confirm the method matches your samples and limits. Choosing the right approach is central to accurate TOC measurement.

Online analyzers give continuous monitoring of a water loop, while laboratory instruments test discrete samples at the bench. Choose based on whether you need real-time assurance or periodic grab-sample testing. Some facilities use both together. Matching format to your monitoring strategy keeps the instrument useful.

Match the analyzer's range to your water type, as pharmaceutical water needs low-level detection while waste water carries higher loads. Confirm the instrument reaches the sensitivity your limits require. Ask the seller about the specified range and detection limit. Aligning range with application ensures reliable results.

Ask when the instrument was last calibrated and whether calibration standards remain available for the model. Regulated water testing usually requires periodic recalibration. Factor a fresh calibration into commissioning if records are older. A documented calibration record shows how close the analyzer is to being usable.

You agree condition, price and delivery directly with the seller once the instrument suits your system. Qualifying listings may be financed, which spreads the cost over an agreed term. Look at the specific analyzer listing to see if finance is available. Dealing with the owner keeps the process transparent.
