liquiTOC II

TOC/TN_b analyzer based on high temperature oxidation with unique capability of additive TIC/TOC, respectively TIC/POC/NPOC or direct TOCdetermination from a single sample injection. The advanced reactor concept incorporates economical design with high analytical performance. The liquiTOC is suitable for applications ranging from high purity water, waste water to solids. The dynamic furnace with variable two-temperature-zones is distinctive for liquiTOC and enables a direct TIC/TOCdetermination in solids by a temperature ramp method without previous acidification - a unique and save method that has no comparison.

Specifications

Measuring method:
high temperature catalytic oxidation up to 1100°C and CO₂-measurement with NDIR for TOC, NPOC, TC, TIC, POC (VOC), DOC.TN_b simultaneously (option). Additive TIC/TOC,TIC/POC/NPOCdetermination or direct TOCdetermination. Optional low cost solids module is available

Large detection range:
0 to 100,000 mg/L C without modifications at the instrument or sample dilution with a detection sensitivity of 50 ppb. Variable sample volume between 0.04 and 4 mL allows also fast multipoint calibration with one standard solution

All parameters from one injection:
the unique design of the reactor combines a two-zone combustion for matrix separation and catalyst protection with the function of a sparger for TIC and POC (VOC). This allows the determination of all parameters from a single sample injection

Fully automatic:
with automatic sample feeder, PC control and evaluation through Windows^®, software according to 21 CFR Part 11. Integrated System Suitability Test

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 an especially favorable cost-performance ratio – with high flexibility and analytical performance

Consumables

Initial outfit:
for installation and training sufficient for approx. 1,000 analyses*

Set of consumables for liquids:
sufficient for approx. 1,500 analyses*

Set of consumables for solids:
sufficient for approx. 1,500 analyses*

Set of small wear parts:
complete collection of joints, couplings and filters for fast and easy changes

*depending on sample matrix

Accessories

Control and evaluation unit:
PC with hard disk, CD-ROM drive, Windows^® operating system (English), TFT flat screen monitor. Ink jet printer with connection cable (necessary for operating the analyzer)

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 TOCanalyzer. Comfortable sample change on permanently installed reactor.
Sample amount: up to 5 g Measuring range: 0.5 µg – 100 mg TIC absolute

Solids-module:
additional equipment for the measurement of carbon containing solids or suspensions according to the direct method. Enables direct TIC/TOCdetermination without external acidification by means of a temperature-ramp program. It is used instead of the module for liquids and thus does not require an additional separate furnace. Fast and easy exchangeable Sample weight: 0 - 1000 mg, depending on substance.Measuring range: 1 µg -100 mg C absolute, depending on substance
