2020 European Aerosol Conference

July 1, 2014 by justin

August 31 – September 4, 2020

We welcome you to join us at the first ever European Aerosol Conference. While the conference is virtual, you will be able to stop by our virtual booth chat with us and discuss the latest from Sunset Lab, and all things carbon aerosol.
The conference will be from August 31-September 4th, and aerosol scientists and engineers from all over the world will participate once again in this conference.  We hope to see you there.

38th Annual AAAR Conference

July 1, 2014 by justin

October 5-9, 2020

Come see us in our virtual booth during the 38th Annual AAAR Conference this October 5-9th.  Due to COVID-19 the AAAR Conference is being held virtually for the first time, but we will still be attending. Come have some live discussion/chats with us, as well as pick up brochures and watch videos of the latest and greatest from Sunset Lab.

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.

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.

Quartz Filters

July 1, 2014 by justin

filters

Our quartz filters are pre-fired  and then packaged in Petri dishes or cassettes, and are ready for sample collection. We offer 25mm, 37mm, or 47mm filters in Petri dishes. We also offer 37mm filters in three-piece plastic cassette samplers.

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.

Lab OC-EC Aerosol Analyzer

June 3, 2014 by justin

aerosol-analyzerThe 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

  • OC-EC measurements for integrated filters and bulk samples
  • Analysis profiles easily selectable to match NIOSH, IMPROVE A, EUSAAR2, STN or custom applications
  • Excellent sensitivity with low instrument background
  • FID detection with linearity over 4 orders of magnitude
  • Built-in FID igniter
  • New and improved microcontroller and data acquisition system for enhanced accuracy and precision
  • Standard transmittance-based pyrolysis correction, resulting in better signal-to-noise and throughput
  • Concurrent transmittance/reflectance option with superior temperature controlled laser system
  • New extended-life heating coils, with PID control algorithm for stable oven temperatures during analysis
  • Quality service and technical support by highly qualified personnel

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:

  • Ambient air quality and environmental exposure measurements
  • Indoor air exposure assessment monitoring
  • Long-term environmental research such as studying the effects of regulatory changes
  • NIOSH exposure assessments in the workplace

 

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.

Features

  • New smaller, lighter rack mountable design
  • Easy access panel for filter service and calibration
  • Analytical results comparable to NIOSH 5040
  • Analysis profiles easily selectable to match NIOSH, IMPROVE, STN or custom applications
  • Optimized photo detector and optical system
  • Minimum quantifiable levels of 0.5 μg C/m3 each of OC and EC
  • Improved NDIR detector with better temperature control and sensitivity
  • 16-Bit data acquisition system with embedded CPU control
  • Computerized flow controllers for all gasses
  • New inline pressure regulators for superior flow control
  • Precision tuned optical alignment for enhanced laser stability
  • Improved temperature control with superior cooling fan configuration to allow more online sampling time
  • New extended-life heating coils, with PID control algorithm for stable oven temperatures during analysis
