Modes
The acquray series is optimized for TOC analysis, but thanks to its flexible instrument concept, additional modules can be added. The following modes are available:Liquid mode
The liquid mode includes the TOC base module for the determination of TOC in liquid samples. It offers an autosampler with up to 111 sample positions. Optional, extra modules for total nitrogen (TN) and total phosphorous (TP) determination in liquid samples can be added.
Solid mode
For the solid mode the optional acquray solid module with manual sample feeding needs to be attached. It offers TOC and TOC400, residual oxidizable carbon (ROC), total inorganic carbon (TIC900), and total carbon (TC) determination in solid samples.
Analytical specifications
Analysis method
UV-/persulfate digestion for injection volumes up to 40 ml for the determination of NPOC, TOC, TIC and TC in liquids. Option for simultaneous colorimetric determination of total nitrogen (TN) und total phosphorus (TP) in liquids. Option for the determination of TOC, TOC400, TC, ROC and TIC900 in solids compliant with DIN 19539 (true temperature ramping) or EN 15936.
In accordance with official standards
The acquray series operates in full compliance with all relevant national and international standards such as ISO 8245, EPA 415.3, ASTM D4839, SM 5310 C, EN 1484 (all about TOC in liquids), DIN 19539, EN 15936 (both about TOC in solids), ISO 29441 (TN in liquids), and ISO 15681 (TP in liquids).

Large detection range
From low ppb up to percent carbon for liquids.
Fully automated operation
Automated and unattended operation is possible by the autosampler, automated acidification module and PC-control through Windows®*. Furthermore, optional 21 CFR Part 11 compliant software is available.
Accessories
Automated acidification
Automated acidification for NPOC determination in liquids.
TN and TP module
Free configurable options for total nitrogen (TN) and total phosphorus (TP) in liquids. TN and TP concentrations are determined by using flow injection analysis (FIA) and photometric detection compliant with ISO 29441 for nitrogen and ISO 15681-1 for phosphorus.
Control and evaluation unit
PC with hard disk, CD/DVD-ROM drive, Windows® operating system (English), control- and evaluation software acquray, TFT flat screen monitor, ink jet printer with connection cable.
Electronic analytical balance (solid mode)
Balance and elemental analyzer form a system. We offer convenient analytical balances from the leading manufacturers with our instruments. Automatic weight transfer from balance to software is possible.

Certified liquid TOC standards
Certified liquid TOC standards for instrument calibration, qualification procedures or troubleshooting.
Solid module
True temperature ramping for TOC400, ROC, TIC900 determination in solids compliant with DIN 19539. Alternative gas switching for combination of oxidizing and non-oxidizing carrier gases in one course to separate ROC and TIC. Isothermal catalytic combustion for the determination of TOC in solids compliant with EN 15936.
Gas generator
As an alternative to gas cylinders also compressors can be used for the carrier gas supply. We offer gas generators for purifying the generated gas according to the analytical requirements.
Unmatched analytical performance:
Limit of detection (LOD) of 10 ppm or < 15 μg C
- The soli TOC® cube is the most sensitive instrument in the market and offers an unmatched measurement range from 0.001 – 100 % carbon.
- Reproducible measurements due to precise adjustable temperature with fast heating rates. Temperature is measured where it matters, directly at the crucible.
- Consistent high measurement quality thanks to the use of a post-combustion catalyst. This ensures that even high carbon-content samples are quantitatively oxidized.
- Optimized separation of residual organic carbon (ROC) and total inorganic carbon (TIC) for special samples thanks to integrated carrier gas switching.
Fast & easy analyses: Autosampler for 24/7 operation & automated ash removal
- Autosampler with 89 positions, optimized for unattended 24/7 high-throughput operation.
- Minimized efforts for sample preparation due to the advanced temperature ramping and the crucible technology.
- Automated ash removal and clearly arranged, easily accessible system components minimize maintenance efforts.
Einfachste Probenvorbereitung: Minimierter Aufwand dank Tiegeltechnologie
- Einfache Analyse von Progeneinwaagen bis zu 3 g.
- Auch inhomogene Proben lassen sich zeitsparend einwiegen und präzise analysieren, da größere Probeneinwaagen den Aufwand für Homogenisierung deutlich reduzieren.
- Komfortable TOC-Messungen gemäß DIN EN 15936 mit direkter Ansäuerung der Probe im alternativen Keramiktiegel.
- Verringerte Kosten für Verbrauchsmaterialien durch wiederverwendbare Tiegel.

Unübertroffene Flexibilität: Anpassbar auf Ihre analytischen Anforderungen
- Optionale Bestimmung des Gesamtstickstoffs (TN) möglich.
- Die Analyse von Kohlenstoff in Flüssigkeiten ist für bestimmte Konzentrationen möglich.
- TOC400, ROC und TIC900 kann in nur einem Verfahrensschritt bestimmt werden. Hierzu werden die unterschiedlichen Bindungsformen des Kohlenstoffs mittels Temperaturrampe aus unterschiedlichen Zieltemperaturen unter oxidativen und pyrolytischen Bedingungen unterschieden.
- Alternativ kann auch das klassische Verfahren mittels Ansäuerung zur TIC Entfernung, Trocknung und anschließender TOC-Messung durchgeführt werden.
- DIN 19539 und DIN EN 15936/ISO 10694 konforme Analysen mit nur einem Gerät möglich.

Nutzerfreundliche Wartung: Komfortabel & werkzeuglos
- Wartung in Sekundenschnelle durch übersichtlich angeordnete, leicht zugängliche Systemkomponenten und ein werkzeugloses Klemmverbindungssystem.
- Die automatische Ascheentfernung sowie die herausragende Robustheit und Langlebigkeit des Gerätes reduzieren Wartungs- und Reparaturaufwände.
- Das werkzeuglose Klemmverbindungssystem sorgt jederzeit für ein dichtes, zuverlässiges Gerät ohne Leckage.
