At SGS, quality isn’t just a checkpoint, it’s our foundation. When it comes to industrial hygiene (IH) sampling, even the smallest inconsistencies can lead to compromised data, incorrect exposure assessments, or regulatory challenges. That’s why we invest in rigorous quality control systems that work behind the scenes to ensure the data we deliver is accurate and defensible.

One of the ways we uphold this standard is through lot verification, a process that confirms every batch of sampling media meets strict performance criteria before it’s used in the field. This helps us detect background variability, contamination, or lot-specific defects that could otherwise go unnoticed.

A Quality-First Approach in Action

Hydrogen sulfide (H₂S) sampling offers a good example of how these quality safeguards benefit our clients. In reviewing current sorbent tube media, we evaluated the performance of multiple available options. Based on those assessments, and in keeping with our commitment to delivering the most consistent, high-quality results, we are currently recommending the Radiello 170 passive badge as a preferred sampling method.

This decision reflects both scientific consistency and client care: by selecting a sampling media with proven performance and strong manufacturer support, we’re ensuring clients continue to receive the reliable data they need to protect worker health and meet regulatory obligations.

Why Radiello?

The Radiello 170 sampler offers several advantages for hydrogen sulfide monitoring:

• Low reporting limit: 0.026 ppm for 8-hour samples
• Flexible sampling times: From 1 hour to 15 days (per manufacturer guidance)
• Radial design: Enhances diffusion rate for accurate collection
• Optional 90-degree adapter: Improves ease of use for personal sampling

These samplers are analyzed in-house by our experts, allowing for streamlined logistics and consistent turnaround times.

Additional Solutions

For clients seeking real-time monitoring, instruments such as the MultiRAE and ToxiRAE, available for rental, provide immediate data with a measuring range of 0–100 ppm and resolution of 0.1 ppm.

We are also continuing to evaluate additional active sampling methods for hydrogen sulfide as part of our ongoing commitment to offering best-in-class IH solutions.

Quality as a Commitment

Our approach is rooted in prevention, not reaction. By building robust quality assurance into our processes, including media verification, method evaluation, and equipment validation, we help clients avoid problems before they occur.
