Sample transport systems present tremendous opportunities for improved analyzer accuracy. Chemical and petrochemical industries around the world have clearly identified that yield, scrap and compliance improvements can be directly attributed to the effectiveness of the sample transport system. Analyzers will function only as well as the transport system yet this same system is often the most overlooked and misunderstood component.

O’Brien Analytical™, a focus of O’Brien Corporation, is dedicated to all aspects of providing customers consistent sample streams. Maintaining acid dew points can present a myriad of process control challenges. O’Brien Analytical offers a wide variety of
engineered solutions and products to ensure consistent sample delivery to the analytical device. O’Brien’s heat transfer expertise with TRACEPAK® and STACKPAK™ tubing bundles and VIPAK® heated analyzer cabinets have made O’Brien Analytical the company of choice for the analytical industry.

From design to installation services, from expertise in heat tracing to tubing materials, O’Brien Analytical provides complete sample stream consistency.

It is our hope that becomes an effective resource for your own use and a place to share information with others. We have broken it down into specific high problem areas:

  • Sample collection and the connections to a preinsulated tubing bundle.
    Here we offer subsections for Stack Gas and Process Analyzers because each of these have different problem areas.
  • Preinsulated tubing bundles.
  • Sample conditioning cabinet and the connection with the tubing bundle.
  • Reference material and links to other sites you will find helpful.

We intend for this site to be continually updated and your feedback and suggestions will be instrumental in making it useful. In the future we will add discussion groups as well to facilitate sharing experiences between users.

Analyzer Applications

Analyzer Sample Line

Accurate, Reliable Samples
Temperature maintenance of your sample line is critical to your analyzer application. Over 80% of all analyzer problems reside in the sample conditioning or transport systems. For accuracy, you must control the temperature, pressure, and flow rate across the entire length of the sample line without changing the chemical makeup of the sample to be analyzed.
