XPERT-TOC/TNb Elemental Analyzer

Product catalog summary

Introduction
TE Instruments provides TEIS Analytical SoftwareTM for elemental analyzers, facilitating control and application management with an intuitive interface. Key features include Auto-Cal for calibration, Method Manager for application settings, and management tools for samples, tasks, and databases.

Specifications
The XPERT-TOC/TNb analyzer is designed for Total Organic Carbon (TOC) and Total Nitrogen (TN) analysis using high-temperature catalytic combustion. It operates at destruction temperatures of 680 °C and 720 °C, with detection techniques including NDIR for TOC and Chemiluminescence for TN. Detection limits are 50 µg/L for TC, TOC, NPOC, and 20 µg/L for TN, with measuring ranges of 0 to 10,000 mg/L for TC, TIC, NPOC, and 0 to 1000 mg/L for TN. Repeatability is less than 5% up to 10 mg/L and less than 2% above 10 mg/L, with an analysis time of 3-4 minutes.

Design and Operation
The XPERT-TOC/TNb features an integrated auto sampler, allowing simultaneous TOC and TNb measurement from a single injection. It uses high-quality NDIR and TN-CLD detectors, with the ProCATTM combustion tube ensuring complete combustion and extended catalyst life.

Performance and Standards
The analyzer complies with international standards such as ASTM D7573, EN-1484, EPA 415.1, and ISO 8245. It includes smart operation features like embedded sensors for continuous monitoring and user notifications.

Company Background
TE Instruments, based in Delft, Netherlands, specializes in elemental combustion solutions, managing the entire production process to ensure high-quality and innovative products like the XPERT-TOC/TNb.

Procedures
The analyzers use direct injection into the furnace or IC-port with a sample injection volume of 10 to 500 µL, defaulting at 100 µL. IC removal is automated through acid addition and sparging, with catalytic combustion at 680 °C or 720 °C.

Standards and Compliance
The analyzers meet standards such as ASTM D7573, ASTM D8083, EN-1484, EPA 415.1, EPA 9060, ISO 8245, ISO 11905-2, and USP <643>.

Software and Features
TEIS Analytical SoftwareTM offers intuitive control and application handling, with features like Auto-Cal for calibration, Method Manager for application settings, and management tools for samples, tasks, and databases.

Physical and Operational Characteristics
The analyzers measure 38 x 44A x 70 cm and weigh between 29 kg and 32 kg. They operate on oxygen and synthetic air with a gas consumption of 150 to 200 mL/min, requiring a power supply of 100 – 240 V AC, 50 – 60 Hz, 16 A.

Complete Sample Combustion After sample introduction, the organic phase reaches the hot zone of the robust and long-lasting furnace, covered by a lifetime warranty. The furnace heats the ProCAT™ combustion tube towards 680 °C - 720 °C, ensuring the complete catalytic oxidation of all your samples into CO2 and NO. The ProCATTM combustion tube guarantees optimal temperature distribution and protects the catalyst at the same time. This results in an extended lifespan of the catalytic material and extremely accurate results. Decades of combustion experience were utilized to create this unique combustion...
