Process Control

Ef uent treatment process control
Processes
(Plating, etching, washing, water-based cutting)
Ultrapure water recycling and
re-puri cation processes

Example of TOC Measurement of Nickel Plating Solution
Analysis instrument: TOC-LCPH
Measurement method: TOC measurement of Nickel Plating Solution,
thousand fold dilution with pure water
(TOC measurement (NPOC measurement) with sample acidi cation and sparging)
Measurement results: TOC = 12.80 mg/L (C.V. = 0.22 %)
(before dilution TOC = 1.280 %)

Investigations and
Experimental Research
Example of TN Measurement of Ammonium Sulfate Aqueous Solution
Analysis instrument: TOC-LCPH + TNM-L
Measurement method: TN measurement of Ammonium Sulfate Aqueous Solution,
prepared nitrogen concentration = 10 mg/L Global environment and eutrophication
Measurement results: TN = 9.91 mg/L (C.V. = 0.30 %)
River water, lakes and marshes, underground water,
sea water, soil, sludge, sediments, etc.

Example of TC (Total Carbon) Measurement of Poultry Manure Compost
Analysis instrument: TOC-LcsH + SSM-5000A (980 °C electric furnace)
Measurement method: direct TC measurement of commercially available
poultry manure compost, pulverized with a mortar
Measurement results: TC = 27.26 %C (C.V. = 0.57 %)
