Sample Conditioning System Explained

It can include probes, heated lines, coolers to remove moisture, filters, pumps, pressure regulators and flow meters. A fast loop returns most flow to the process.

Most analyser problems come from the sample system, not the analyser itself.

Frequently Asked Questions

What is a Sample Conditioning System?

A sample conditioning system takes a process sample and makes it suitable for the analyser: filtered, cooled, pressure and flow controlled.

Why heat sample lines?

To stay above dew point so water and soluble gases do not condense.

What is a fast loop?

A high flow bypass that brings fresh sample close to the analyser.
