Shimadzu On-l ine Total Ni t rogen/ Phosphorus/TOC Analyzer

Product Introduction

Nitrogen and phosphorus are substances considered factors in the over-proliferation of organisms in rivers, lakes, coastal waters, and other public waters, particularly enclosed bodies of water. For this reason, there is a strong need to monitor wastewater and public bodies of water. The Shimadzu On-line Total Nitrogen/Phosphorus Analyzer TNPC-4110 Series addresses this need. With a simple design, only small quantities of chemical solutions and waste liquids are required,and maintenance operations are simple. Chemiluminescence, a method that is resistant to interference from compounds,for example, when measuring seawater, is used for total nitrogen measurement. In addition, we offer the TNPC-4110C,a model capable of measuring the organic pollutant index, TOC. This is the optimal on-line water analyzer for comprehensive assessment of water quality, including organic pollutants.

FeaturesA simple design with a proprietary metered distribution system. Only a few parts require periodic replacement, and maintenance is easy.Only small quantities of chemical solutions are used, and waste liquids are also minimal.Reagent replacement is once per month, and waste liquid management is every two months(assuming a 1-hour measurement cycle).A chemiluminescence system is adopted for TN measurement.Suitable even for samples containing seawater, metallic ions and other compounds that interfere with the UV method.

ApplicationsWastewater monitoringMonitoring of influent and effluent from wastewater treatmentMonitoring of public waters including rivers, lakes, and dams

Shimadzu Proprietary Metered Distribution System: 8-Port Valve Syringe Pump

Measurement Procedure

All operations, from water sampling to dilution, reactant distribution, mixing, and solvent delivery, are performed by the syringepump and 8-port valves

This unit will reduce maintenance frequency and flow blockages, the biggest problems for on-line analysis.The design is suited to measuring samples of suspended particles.

It has a unique sampling mechanism that does not use solenoid valves.By obtaining only the minimum sample quantity necessary, not only are problems with suspended particles reduced, but problems with slime and algae are reduced as well.A strainer-equipped homogenizer is included.All sample contact components are rinsed and the strainer is backwashed immediately after samples are obtained.

Compatible with multi-stream measurement. Contamination between streams is minimized with this pretreatment unit.

Simple and effective sample pretreatment unit.

Air* pushes the sample material out of the sampler to

prevent adhesion of contaminants, slime, and algae, and

acts to backwash the strainer to prevent clogging.

A sterilizer is installed along the air flow path, preventing blockage of

the strainer from the growth of micro-organisms, and controlling the

production of slime and algae within the chamber.

When collecting water samples, the sample enters the

sampler through the strainer.

*Compressed air and rinse water (tap water) are required.

Backwash Strainer Sample Pretreatment Unit

This unit will reduce trouble with flow blockages,the biggest problem for on-line analysis.The design is suited to measuring samples of suspended particles.

The electrically operated suspended solids pretreatment unit does not require a compressed air source.Stable measurement values are obtained by means of a 2-stage pretreatment process. This consists of removing foreign matter with the strainer, and then pulverizing the suspended particles and ensuring homogeneity with the homogenizer.Samples are sent via the strainer to the pretreatment section only when obtaining samples. Furthermore, all sample contact components are rinsed with rinse water immediately after samples are obtained. By introducing only as much sample as is necessary and then promptly washing, problems with slime and algae are also reduced. In addition, a built-in sterilizer provides even more effective control over slime and algae production.
