AIHce EXP 2020 - Virtual Conference

Nanozen is proud to be participating in this years AIHce Virtual Conference and Exposition. Join us on Wednesday June 3rd for two exciting presentations on dust monitoring from our industry experts. Also don’t forget to stop by our virtual booth, Hayley will be available online to answer any of your questions throughout the conference event!

Conference Presentation

OPC vs. Photometer in a Controlled Laboratory and in Wildfire Sampling

To improve protective measures for workers, a major push in aerosol monitoring with regards to industrial hygiene is the movement from gravimetric monitoring to real time monitoring. Real time monitoring measures and reports live aerosol concentration, alerting the user of dangerous exposure levels. It also allows professionals to visualize aerosol exposure over a whole shift, rather than having the average exposure provided by post sample analysis. With this information, analysis can be performed to identify problematic areas where the user was exposed to abnormally high or dangerous levels of aerosols. Currently on the market there are two dominant technologies when it comes to personal real time aerosol monitoring: optical particle counters (OPC) and photometers. Both technologies utilize laser as detection source; however, each has its own unique pros and cons. This study is designed to outline and test these differences as well as use real world wildfire sampling as an example.

Dr. Winnie Chu will be presenting in a session focused on Exposure Research along with experts from CDC, Enbridge and NW Natural.

Wednesday June 3, 1:00 pm – 2:00 pm EDT

Conference Presentation

Sampling and Interpretation Errors in Workplace Aerosol Monitoring

Today, a multitude of personal sampling devices, ranging from simple filter collection sampling pumps to sophisticated real-time particle spectrometers, are available to industrial hygienists for workplace aerosol exposure assessment. Regardless of the technology employed, aerosol exposure monitoring may introduce sampling errors and influence the interpretation of measurements. The aerosol measured by personal samplers may differ substantially from the original aerosol due to factors such as sampling efficiency, transport and internal losses, sensor response limitations, and inadequate sampling and data processing.

This study aims to investigate how different sources of sampling error (bias and variability) may affect the measurement of the original aerosol. Understanding the sources and significance of these potential errors enables the industrial hygienist to circumvent the sampling inaccuracies, and more accurately assess the health implications of aerosol exposure measurements.

Dr. Amin Engarnevis will be presenting in a session focused on Air Sampling Research Updates along with experts from Lawrence Livermore National Laboratory, Georgia Institute of Technology and Gulf Coast HSE Consulting Services. 

Wedneday June 3, 2:15 pm – 3:15 pm EDT

Virtual Exhibit

While we are disappointed not to be able to see everyone in Atlanta this year, we are committed to making sure you get all your questions answered about best practices in dust monitoring and state-of-the-art devices such as our DustCount 9000. Hayley Croteau, Nanozen’s Vice President of Sales will be available via Zoom and other communication tools throughout the conference to answer all your questions.
