Key Benefits
- Low detection limit — 2 ppb instrument detection limit (IDL) suitable for drinking water and ultrapure water quality monitoring
- Wide dynamic range — single instrument covers 10 ppb to 30,000 ppm — drinking water through to industrial wastewater in one calibration range
- High throughput — up to 300 samples per 24-hour period; optional concurrent dual-chamber processing for increased productivity
- Regulatory compliance — supports USEPA, Standard Methods, ASTM, DIN/ISO/CEN, USP, and EU methods; 21 CFR Part 11 compliant ATOC software
Overview
The Aurora 1030W is a benchtop total organic carbon analyser from OI Analytical (Xylem), using the proven heated sodium persulfate oxidation method with non-dispersive infrared (NDIR) detection. The reaction chamber is thoroughly rinsed between analyses to eliminate carryover, maintaining the low system background essential for high-sensitivity TOC measurements.
With a 2 ppb instrument detection limit and a range extending to 30,000 ppm, the Aurora 1030W covers drinking water, pharmaceutical cleaning validation, environmental monitoring, and process water applications in a single instrument. Throughput of up to 300 samples per 24-hour period supports busy laboratory workflows.
The optional 88-position rotary autosampler mounts directly underneath the analyser to conserve bench space, and ATOC software provides 21 CFR Part 11 compliant data handling for pharmaceutical environments. Walker Scientific supplies and supports the Aurora 1030W across Australia, New Zealand, and Africa.

Frequently Asked Questions
What oxidation method does the Aurora 1030W use?
The Aurora 1030W uses heated sodium persulfate wet oxidation with non-dispersive infrared (NDIR) detection. This proven method ensures complete oxidation of organic carbon across a wide range of sample matrices.
What is the detection limit of the Aurora 1030W?
The instrument detection limit (IDL) is 2 ppb C. The analyser can be programmed and calibrated to measure samples from as low as 10 ppb up to 30,000 ppm.
What parameters can the Aurora 1030W measure?
The Aurora 1030W measures total organic carbon (TOC), total inorganic carbon (TIC), and non-purgeable organic carbon (NPOC).
Is the Aurora 1030W compliant with pharmaceutical TOC requirements?
Yes. The Aurora 1030W supports USP TOC testing methods and the ATOC software provides 21 CFR Part 11 compliant data handling, security, audit trails, and reporting.
What autosampler options are available?
An optional 88-position rotary autosampler is available. It mounts directly underneath the Aurora 1030W to conserve bench space while enabling unattended batch analysis.
What is the sample throughput?
The Aurora 1030W can process up to 300 samples per 24-hour period. An optional second oxidation chamber supports concurrent sample processing for increased productivity.
What regulatory methods does the Aurora 1030W support?
The Aurora 1030W supports USEPA-approved methods, Standard Methods, ASTM, DIN/ISO/CEN, USP, and EU Methods for TOC analysis.
