If left unopened and sealed in the package, PeCOD sensors have a shelf life of 12 months. Once opened and in use, sensors can be expected to last for approximately 1 month or 200 samples [...]

The PeCOD® measures COD through a rapid 10-minute photoelectrochemical oxidation, allowing for the accurate monitoring of a wide range of concentrations in real-time. These COD readings can be [...]

MANTECH utilizes rapid dipping of conductivity probes into sample tubes to mix samples and ensure a stable analysis of conductivity from the probe. This style of mixing is applicable to systems [...]

MANTECH recommends the use of turbidity standards made with suspensions of microspheres of styrene-divinylbenzene copolymer for all turbidity applications. Standard Methods dictate that [...]

Standard Method 2130B (Nephelometric Method) specifies that a laboratory or process nephelometer should have a detector system with a spectral peak response of 400 to 600 nm. MANTECH’s T10 [...]

For water soluble contaminants, rinse probe in deionized (DI) water.  If ineffective, soak probe in warm DI water with household detergent for 15 – 30 minutes. For oil-based contaminants, [...]

The timing for analysis of different parameters depends on a few different factors, like the concentration of the sample and the equipment used. Another factor is the total available sample [...]

A separate standard produced by Sigma Aldrich is used for quality control testing of PeCOD systems. This allows for verification of results and ensures that the system in use produces trusted [...]

Calibrations can be linear, logarithmic, single-line, and multi-line fit.  The calibration method used depends on the method required. pH and Color calibrations are linear, single-line fit [...]

IntelliRinse™ is beneficial because it uses real-time measurement to provide confirmation that your probes are 100% clean, eliminating chances of cross-contamination. Active IntelliRinse™ systems [...]
