    Pulp and paper

    Laboratory and online instruments for pulp, paper and wood pellet mills.

    We deliver three complementary workflows for the pulp and pellets industry: halogen, sulphur, and nitrogen analysis in the lab (Nittoseiko), mercury analysis (NIC), and on-line moisture measurement (KPM), well established also in wood pellet production. Configuration, commissioning, and calibration are included.

    Three workflows for the mill and pellet industry.

    We cover three complementary areas for pulp, paper, and wood pellet mills: laboratory-based halogen, sulphur, and nitrogen analysis, dedicated mercury analysis, and on-line moisture measurement in process, including moisture in pellets and raw material.

    Halogens, sulphur and nitrogen in the lab (Nittoseiko)

    Determination of total halogens, organic chlorine and fluorine, total sulphur and total nitrogen in the sample preparation laboratory. Includes titration equipment. Laboratory-based analysis, not online process measurement.

    Mercury analysis in various forms (NIC)

    Dedicated instruments for mercury determination in solid, liquid, and gaseous samples. Low detection limits and traceable calibration for process and emission monitoring in industrial environments.

    On-line moisture content measurement (KPM)

    Continuous moisture measurement directly on the line for reliable feedback to process control. Stable operation over long cycles in industrial environments.

    Manufacturer for the industry.

    For pulp and paper, we work with three manufacturers who together cover three workflows: lab analysis of halogens, sulfur, and nitrogen; dedicated mercury analysis; and on-line moisture content measurement. All three have an installed base in the Nordic region.

    Nittoseiko

    Japanese manufacturer of lab instruments for the analysis of halogens (including organic chlorine and fluorine), sulfur, and nitrogen, as well as titration equipment. We distribute the Nittoseiko portfolio in the Nordics for the quality labs of the mill industry.

    See the Nittoseiko portfolio

    NIC

    Nippon Instruments Corporation manufactures dedicated instruments for the analysis of mercury in various forms. Used in process and emission monitoring in industrial environments where low detection levels and traceable calibration are required.

    See the NIC portfolio

    KPM Analytics

    US manufacturer of on-line process instruments. We distribute the KPM portfolio in the Nordics for continuous moisture content measurement directly on the line in pulp and paper mills.

    Nittoseiko products for pulp & paper.

    Nittoseiko laboratory instruments are used in mill and pellet quality laboratories for the determination of total halogens, AOX/TOX in bleachery and process water, total sulphur and total nitrogen, as well as moisture by Karl Fischer titration. Configured to the mill's matrices and reference methods.

    AQF-5000, halogens and sulphur

    Combustion with ion chromatography for determination of total halogens (F, Cl, Br, I) and sulphur in solid samples, liquids and sludge; suitable for recovered fibre, bleached pulp and process samples with complex matrices.

    NSX-5000, sulphur and nitrogen

    Determination of total sulphur (UV fluorescence) and total nitrogen (chemiluminescence) in the same instrument. Used for routine control of pulp, bleaching chemicals and process water in the mill laboratory.

    AOX-400 / TOX-300, organic halogens

    Dedicated instruments for AOX (adsorbable organic halogens) in bleaching and wastewater as well as TOX in solid samples, established key parameters for the mill industry's environmental reporting in accordance with EN ISO 9562.

    Standards and reference methods.

    Measurements must be traceable to established standards. For halogen, sulfur, nitrogen, and mercury analysis, we work with reference methods that your QA organization and your clients' auditors already recognize.

    • ISO 17025 for traceability in calibration, documentation and reporting.
    • ASTM D7359 for determination of total halogens via combustion and ion chromatography.
    • ASTM D5453 for total sulphur via UV fluorescence.
    • EN 1483 and related methods for mercury analysis.

    Initial calibration is performed against certified reference material and the mill's own laboratory method. Re-calibration is scheduled according to the service contract.
