# Why Sampling Systems Haven't Improved

## Three Main Reasons

#### ![Sampling-WhyHaventImproved (1)](https://northerncal.swagelok.com/hs-fs/hubfs/2020%20-%20Resources%20thumbs%20(compressed)/Sampling-WhyHaventImproved%20(1).jpg?width=300&name=Sampling-WhyHaventImproved%20(1).jpg)Analyzers keep improving, but sampling systems have three strikes against them. Get this article to review why.

In the past 50 years, process analyzers of all kinds have gotten better and better, but sampling systems have not. This is a strange set of developments.

Many process analyzer sampling systems in today’s plants are not fulfilling their intended purpose, which is to deliver an uncontaminated, representative sample to the analyzer without excessive time delay.

The result is compromised or inaccurate analyzer readings and, by extension, chemical and petrochemical products that are not within specifications. There is also the potential for safety issues associated with improperly designed sampling...
