A thermal-optical carbon analyzer that separates organic from elemental carbon in collected particulate, supporting both transmittance and reflectance charring correction. Which correction you use changes the split — so an instrument that does both lets a dataset stay comparable with whichever protocol it must be read against.
Key features
- Precise OC/EC measurement for source identification based on thermal-optical method.
- PID-controlled furnace for stable, long-lasting performance.
- Dual optical correction (TOT & TOR) for compliance.
- Integrated automation with easy-to-use software.
Applications
Built for aerosol chemistry, source apportionment and air-quality research groups.
- Photochemical Pollutants Monitoring System

What does this instrument measure, and who is it for?
It measures the split between organic and elemental carbon in collected particulate. It is built for aerosol chemistry, source apportionment and air-quality research groups. It is designed for continuous, unattended operation in a monitoring shelter or cabinet, with periodic zero and span calibration.
What measurement principle does it use?
Thermal-optical analysis of a collected deposit, supporting both transmittance and reflectance charring correction. The correction chosen changes the split, so an instrument that does both keeps a dataset comparable with whichever protocol it must be read against.
Which specifications are confirmed?
The manufacturer's published specification table lists nine parameters for this instrument, and every one of them is reproduced on this page. They include Detection Method at CO2, NDIR, Range at (0~1000) μg/m³ and Detection Limit at <0.6ug/m³. ConductScience transcribed them from the manufacturer's engineering documentation without alteration.
What should be confirmed before ordering?
Confirm siting and inlet configuration, zero and span gas supply, the calibration interval your reporting regime requires, and the data acquisition and reporting path. These are configured and quoted per installation, so raise anything unusual about the site during quote review rather than after delivery.
What else is needed to run it?
A zero air generator and a multi-point dilution calibrator. Every concentration this analyser reports is measured against its zero. A zero that is not actually zero is a systematic error in every number downstream of it, so the calibration gear is not an accessory — it is what makes the readings defensible.
How is it supplied?
This instrument is configured and quoted per installation rather than sold at a list price. Request a quote and we will confirm the configuration, the site requirements and the lead time before anything is ordered.
