vario TOC cube

Measuring method
High temperature catalytic oxidation up to 1200 °C and CO₂-measurement with NDIR for TOC, NPOC, TC, TIC, POC (VOC), DOC. TN_b determination simultaneously with EC, NDIR or CLD (option).

Large detection range
From low ppb to percent. Variable sample volume allows also multipoint calibration from a single standard solution with auto-dilution-effect. Extraordinary linearity over the entire calibration range.

Modular concept for liquids and solids analysis
Large choice of automatic sample feeders for liquids and solids, alternatively cost-efficient solutions with manual sample change. Quick and easy exchangeable. With possibility to upgrade at any time.

Real matrix separation
The new reactor concept enables real matrix separation and offers maximum protection of the combustion tube. Excellent properties for analyses of saline solutions (e.g. brine) or other complicated sample matrices.

Software with high performance and maximum flexibility
Instrument control with a Windows standard PC, control and evaluation software with calibration wizard, system suitability test, statistics and advanced math operations, opt. according to 21 CFR part 11. Integrated maintenance software and comprehensive help menu.

Supports validation
Complete qualification documentation with Standard Operation Procedures (SOPs) and Certificates for IQ, OQ and PQ according to FDA regulations

Easy, compact, economical
The unique instrument concept is characterized by easy handling and optimized for low maintenance costs – with high flexibility and analytical performance.

Control and evaluation unit:
PC with hard disk, CD/DVD-ROM drive, Windows^® operating system (English), Control- and evaluation software vario TOC cube, TFT flat screen monitor, Ink jet printer with connection cable.

Sample injection modules for liquids
Large choice of automatic sample feeders for liquids, fully integrated into the instrument. All positions can be stirred and purged.

• 32 positions with 40 mL vials with septa
• 50 positions with 12 mL vials with screw taps
• 80 positions with 6 mL vials

Alternatively cost-efficient solution with manual sample change, with or without integrated stirrer available. Quick and easy exchangeable against solids sample feeder.

Sample insertion modules for solids 
Fully automation for solids analysis with sample feeder for up to 80 samples (max. weight 1 g*) or up to 120 samples (max. weight 300 mg*). Alternatively cost-efficient solution with manual sample change available. Quick and easy exchangeable against liquids sample feeder.

Attachment for TIC-determination in solids soliTIC
Attachment for safe acid digestion of ground solids. Release of the carbonate carbon (TIC) as CO₂ for the measurement with the detector of the attached TOC analyzer. Comfortable sample change on permanently installed reactor.
Sample amount: up to 5 g
Measuring range: 0.5 µg – 100 mg TIC absolute

TN_b determination
Choice of different detectors for the simultaneous determination of total bound nitrogen (TN_b).

• EC – TN_b detection with a cost-effective electrochemical cell

• NDIR – TN_b detection with infrared detector of high performance and extraordinary linearity.

• CLD – TN_b detection with chemiluminescence detector

Helpful tools
Choice of additional helpful tools is available, such as external flask holder for fast calibration from a single standard Teflon^® tray for easy handling and organization of solid samples and more.
