TNPC-4110/4110C Online Total Nitrogen/Phosphorus/TOC Analyzers
Automatic Water Analyzers

The TNPC-4110 is an easy to handle and simple to maintain total nitrogen/phosphorous/carbon analyzer intended for use as an automatic water analyzer for the water quality regulations, governing total nitrogen and total phosphorous.
The TNPC-4110 has the optional capability of measuring Total Organic Carbon (TOC). This complete system is capable of pretreating, digesting, and analyzing the sample automatically; as a result, it saves time and labor, and eliminates errors associated with sample preparation.
The TNPC-4110 series utilizes the contact thermal decomposition/chemiluminescence method to measure total nitrogen, and measures phosphorous through the use of Ultraviolet oxidation decomposition/molybdenum blue absorptiometry.
