Karl Fischer Coulometric Trace Moisture Analysis with Model CA-310

Japanese manufacturer Nittoseiko Analytech Co., Ltd. (formerly Mitsubishi Chemical Analytech) develops automated Karl Fischer moisture titrators for analytical laboratories.

Coulometric Karl Fischer titration relies on electrolytic iodine generation at the platinum anode. High detection sensitivity enables precise moisture determination down to 1 microgram in insulating oils, fuels, and organic solvents without manual reagent factor calibration.

Multi-Channel Station Configuration and VA-300 Vaporizer Ovens

The modular CA-310 titration platform operates up to four independent titration cells simultaneously across coulometric and volumetric modes.

To measure insoluble solids, polymers, and battery materials, the system connects VA-300 series thermal vaporizers. Carrier nitrogen gas conveys liberated water vapor directly into the titration cell, protecting electrodes from sample matrix contamination.

High-Temperature Combustion and Trace Detection in NSX-5000 Analyzers

The NSX-5000 elemental analyzers quantify trace sulfur, nitrogen, and halides in petrochemical feedstocks according to ASTM D5453 and D4629 standards.

Inside dual-zone quartz combustion furnaces, samples pyrolyze under controlled oxygen and argon flows. UV-fluorescence and chemiluminescence detectors measure ultra-trace element contents down to 20 parts per billion.

Four-Pin Probe Surface and Volume Resistivity Testing by Loresta

Loresta-GX II and Hiresta-UX resistivity meters employ precision four-pin probe configurations for sheet resistance and resistivity characterization of conductive films and wafers.

Separating excitation current and voltage measurement pins eliminates contact resistance artifacts. Microprocessors apply automated geometric correction coefficients to compute volume resistivity across broad conductivity ranges.

Automated Potentiometric Titrations and Precision Burette Dosing GT-310

Model GT-310 automatic potentiometric titrators automate acid-base, redox, precipitation, and complexometric titrations in chemical quality control.

A stepper motor drive dispenses reagents with a 1/20000 burette resolution. Advanced titration curve inflection recognition algorithms identify true equivalence endpoints across complex multi-component matrices.

Automated Combustion Pretreatment for Ion Chromatography AQF-5000

AQF-5000 automated quick furnaces pyrolyze solid and liquid samples for direct halogen and sulfur quantification via combustion ion chromatography.

Thermal decomposition off-gases are absorbed into aqueous solutions within the GA-211 absorption unit before automated injection into an ion chromatograph. The automated closed combustion path prevents volatile halogen loss and sample cross-contamination.
