This guide explains how Swagelok pressure regulators reduce delay in analytical systems for gas and liquid samples, covering configuration and application.
Analytical instruments often suffer from response delays caused by the time it takes fluid to travel from the sampling point to the analyzer. This document identifies the sampling port location, tubing volume, and probe size as primary sources of this delay. It emphasizes that pressure control is a key method for minimizing this lag. This manual is written in Chinese.
In flow-controlled gas systems, lower pressure results in shorter delay times.
The amount of delay reduction is proportional to the absolute reduction in pressure; halving the pressure halves the delay.
A heated regulator is required when the Joule-Thomson effect causes gas cooling and condensation near the dew point.
