What is the best sampling system for my analyzer?

Process sampling systems – the method by which you get reliable samples for your process analyzer – is just as important as analyzer selection. Unreliable or bad samples can cause major process line errors or false readings, leading to downtime and out-of-spec product.

There can  be several challenges to getting reliable samples, depending on your application. This video by Swaglok does a great job explaining some of the more common issues encountered:

As to which type of sampling system works best for your application, this is where Durkin’s half-a-century of experience working with process instrumentation can really help. Our specialists can help you select the right analyzer and setup a reliable sampling system complete with process controls, SCADA, and data collection.

To get oriented on the subject, you can check out Control Global’s “Introduction to Basic Sampling Systems“, or read about some of the more common types in this American Chemical Society article. An experienced analyzer technician is the recommended method for making sure you get the right sampling system and analyzer instrumentation.

Which analyzer is best for my application and where do I get pricing?

Every situation is unique and which analyzer you need, how much automation it should come with, and how much it will cost depends on many factors including your operating environment, flow rates, chemical composition and many other factors. Durkin’s process specialists can help you determine the specific analyzers and sampling systems that suit your application, budget, and expected life-span the best.

What are process analyzers?

Process analyzers are sensors and probes used to determine the chemical composition or physical properties of substances being manufactured. They provide real-time sampling and feedback to process controllers, so adjustments to the making process can be immediately effective in keeping products within specifications and the manufacturing process safe.

Most modern analyzers are auto-analyzers – a sample stream of flow from the process equipment is constantly going through the analyzer, which automatically makes process adjustments for pressure, temperature, flow rate, etc.

What are common types of process analyzers?

Process analyzers can be categorized several different ways.

The top level categories are:

Destructive analyzers vs non-destructive analyzers. Destructive analyzers modify the sample flowing to them so that it cannot be returned to the regular product stream. Non-destructive analyzers rely upon electromagnetic radiation, sound, and inherent material properties to measure samples so that they are not destroyed and can be returned to the regular product stream.

Online vs. Inline analysis – Online analyzers are connected to the process and conducts automatic sampling. Inline analyzers rely on sensors place in process vessels or stream to conduct the analysis.

Beyond these categories, more specific types of analyzers include:

  • Tunable diode lazer analyzers (TDLAS)
  • Oxygen analyzers
  • Paramagnetic oxygen analyzers
  • Infra-red gas analyzers
  • Dust monitoring systems
  • Mass flow meters
  • Gas chromotography detectors
  • Thermal conductivity detectors
  • Flame ionization detectors (FID)
  • pH analyzers
  • Conductivity analyzers
  • Temperature sensors
