We welcome you to join us in Gothenburg, Sweden for the 2019 European Aerosol Conference. The conference will be held at Svenska Massan/The Swedish Exhibition & Congress Centre in the heart of Gothenburg. Find us at booth 6.
The conference will be from August 25-30th, and aerosol scientists and engineers from all over the world will participate in this conference. We hope to see you there. #GoEAC2019
Come see us at the 38th Annual AAAR Conference this October 5-9 in wonderful Raleigh, North Carolina. The conference is being held at the Raleigh Convention Center in downtown Raleigh.
The AAAR Conference is an outstanding venue to present your latest findings to an intellectually engaged, diverse and professionally-dedicated community and to immerse yourself into the latest advances and the state-of-the-art technology across the full spectrum of aerosol research. The AAAR Conference provides an excellent opportunity to renew old acquaintances and to meet new colleagues from industry, government and academia.
Required fields are indicated in red.
We use careful system control and continuous monitoring of the optical absorbance of the sample during analysis. This prevents any undesired oxidation of original elemental carbon and corrects for the inevitable generation of carbon char produced by the pyrolitic conversion of organics into elemental carbon.
For any size of filter in the petri dishes, the cost is $6.00 per filter and there is a minimum quantity of 10 filters per order. For the 37mm filters in the plastic three-piece cassettes, we accept minimal orders of 5 and charge $10.00 each. Filter orders can usually be sent out the day after the order is placed. For ordering or information please contact us.
Our Parallel-plate Carbon Filter Denuders remove semi-volatile organic carbon vapors. Without Denuders, absorption artifacts will be present on a following quartz filter.
The Lab OC-EC Aerosol Analyzer is the industry standard for environmental and workplace monitoring. This instrument uses a proven thermal-optical method to analyze for OC-EC aerosols collected on quartz filters.It is the basis for NIOSH Method 5040 and is fully compliant with the IMPROVE protocol. It features a new and improved microcontroller and data acquisition system for enhanced accuracy and precision. There is no comparable instrument on the market today.
In the Lab OC-EC Aerosol Analyzer, samples are thermally desorbed from the filter medium under an inert helium atmosphere followed by an oxidizing atmosphere using carefully controlled heating ramps. A flame ionization detector (FID) is used to monitor the analysis. Our proven low dead volume carrier gas control system and proprietary quartz oven design provide high sensitivity with ultra low carbon background and no oxygen contamination.
Features
The Model-4 Semi-Continuous OC-EC Field Analyzer features the latest advances in electronic and optical technology, and is rack mountable!This rugged and compact instrument offers sensitive and reliable field operation with an optimized oven and detector design. Its access panel allows for easy filter service and calibration. New safety mechanisms and inline pressure regulators offer superior flow control.
This analyzer is perfect for:
This instrument is the only commercially available field deployable OC-EC analyzer with true laser-based pyrolysis correction and compatibility with accepted NIOSH 5040 and IMPROVE methods. It has a computer controlled flow system for enhanced sensitivity and fast analysis times. It also has a reduced need for support gases. The Model-4 Semi-Continuous OC-EC Field Analyzer has been extensively tested at several EPA super-sites and demonstrated excellent sensitivity, compared with other co-located integrated filter sampling systems.
