Webinar: Air sampling without the spreadsheet headaches: improving accuracy, traceability, and reporting
Thursday, July 16, 2026,1:00pm Central
Managing air sampling data with spreadsheets can be time-consuming, error-prone, and difficult to validate during audits or reporting reviews. Manual calculations, disconnected calibration records, and inconsistent documentation can create unnecessary challenges.
Join us on June 10 with Dylan Staack of OHD to learn how modern software tools can improve data integrity, simplify documentation, and create audit-ready reports with traceable calibration and validated sampling data.
This webinar will cover:
- Traditional data management strategies for air sampling programs
- Understanding how to use pump data to validate a sampling period
- Using software tools to create traceable calibration records
- Creating reports using validated pump data with traceable calibration information
- How Gilian CONNECT Pro simplifies sampling event organization and reporting workflows
About the speaker: Dylan Staack is an industrial hygienist with years of experience in the industry as a consultant, instrumentation technical expert, and national sales manager. He works with universities and companies across the US to ensure their instrumentation needs are met for their exposure monitoring programs and currently serves as technical applications and partnership director for OHD. Dylan completed his MPH in environmental and occupations health and safety at the University of Arizona. While there, he was a project manager on multiple research projects, focusing on firefighter exposure and cancer rates.
