Total nitrogen/total phosphorus online analysers

Shimadzu's TNPC-4110 series online analysers are capable of simultaneous measurement of total nitrogen (TN) and total phosphorus (TP) in water. Easy to handle and maintain, the analysers are intended for use as automatic water analysis systems. The device provides a complete system that is capable of pre-treating, digesting and analysing the sample automatically, saving time and labour and eliminating errors involved in sample preparation.

The series offers a number of capital as well as operational cost-reducing features. A single unit can analyse multiple streams without requiring transport of samples to the laboratory, and the optional 'Sample Thief' eliminates the need for expensive filters when analysing particulated sample streams.

Total organic carbon (TOC) can also be monitored in addition to the TN/TP on the optional TNPC-4110(C) Series. These models incorporate automatic calibration using standard onboard solutions as well as user-defined calibration checks and measurement conditions. Measurement ranges from ppb level to thousands of ppm for TN, TP and TOC.
