Swagelok Tech Talk Series: Sampling System for On-line Analyzer
Episode 1 — Lag Time (Time Delay)
If your on-line analyzer reads "late," you're deciding on data that has already passed.
In an analyzer sampling system, the value your analyzer reports reflect the process condition from lag time (time delay). The longer the delay, the greater the impact on process control, product quality, and safety. In this focused 2-hour session, we break down where lag time comes from, how to calculate it, and how to design a system that delivers a timely, representative sample.
Scope — What You'll Learn
- What Lag Time / Time Delay is, and why it matters to on-line analyzer accuracy and process control
- Sources of time delay in a sampling system: transport line, sample conditioning components, dead volume / dead legs, and analyzer response time
- How to calculate time delay — the effect of tubing ID, length, flow rate, pressure, and sample phase (gas / liquid)
- Design techniques to reduce lag time: fast loop / bypass loop, tubing sizing, and minimizing dead volume
- A live demonstration and real-world case example
