Sensor lifetime depends on a number of factors including frequency of use, storage conditions, nuances of certain sample matrices, and time between uses. Sensors are expected to last for [...]

There is a strong correlation between the PeCOD COD results and the dichromate COD results. To determine this, the two methods were compared vs. the theoretical oxygen demand (ThOD) for 34 [...]

Both Calibrant and Standard Solutions are good for one year after they are made. Electrolyte has a shelf life of two years after it is produced. All labels have the expiry date in the box just [...]

Open the top plastic door by pushing down firmly on the front centre of the door until a “click” is heard, then release the door. Open the PeCOD analyzer module by pressing firmly [...]

Alkalinity is the buffering capacity of a solution. It is a valuable water quality parameter used for many applications, including, but not limited to: drinking water treatment, domestic and [...]

Calibrations are comprised of 6 different stages. The first stage is called the “Normalization Phase” and lasts 100 seconds. During this time, the LED strength is adjusted to maintain a baseline [...]

Gran analysis is an effective alternative method for endpoint and pKa detection. Using a series of mathematical manipulations, standard titration curves are transformed into linear data called [...]

KHP (Potassium Hydrogen Phthalate) has historically been a common reference standard used in a variety of chemistry applications including the traditional dichromate COD test, where it does [...]

On average, the cost per sample can range anywhere from $2.44-$3.00 per sample. The cost per sample varies depending on the COD/BOD range and the number of samples analyzed, as this affects [...]

The following tables summarize the impact of a range of common inorganic anions and cations on the determination of COD using the PeCOD® technique. You can download this FAQ as a pdf document at [...]
