What is sampling equipment used for in process systems?

Sampling equipment is used to take representative samples from process pipelines, reactors, or vessels without contamination. Accurate sampling is critical for ensuring correct test results and maintaining process performance.

What types of sampling systems does De Dietrich offer?

De Dietrich offers a range of sampling systems including inline samplers, surface-mounted samplers, vessel-mounted sampling systems, and sample dispensing solutions. These systems are designed to meet different process configurations and requirements.

How does De Dietrich ensure safe and accurate sampling?

De Dietrich sampling systems are designed with features to prevent contamination and ensure representative samples. They support safe handling of toxic, flammable, and corrosive media, with options for containment, material compatibility, and controlled dispensing.

Common Sampling Challenges

Safer, more representative sampling for difficult process conditions

The right sampling system depends on where the sample is taken, how representative it must be, what hazards are present, and how the operator will safely collect and transfer the sample. Here are some common sampling challenges that we can help solve for you:

Representative samples: Reduce contamination, carryover, and reduce contamination and carryover.
Reduced Operator exposure: Use contained dispensing, venting, cabinets, septum bottles, or syringe sampling.
Corrosive media: Configure wetted parts around chemical compatibility requirements.
Vacuum or pressure: Match the sampling system to actual process conditions.
Retrofit constraints: Adapt sampling points to existing vessels, nozzles, and large pipelines.

Selection Guide

Choose the right sampling starting point

Your application	Recommended starting point	Why it fits
Sampling from a process pipeline	Inline sampler	Designed for representative samples from horizontal or vertical process piping.
Sampling from a large pipeline or vessel wall	Surface mounted sampler	Bolts to a vessel pad flange or large pipeline connection when inline installation is difficult.
Sampling from a reactor	Vessel mounted sampling system	Uses a dip pipe, site vacuum, eductor, vessel pressure, or a recirculating pump.
Corrosive media	PFA-lined or corrosion-resistant wetted parts	Protects wetted surfaces in aggressive chemical service.
Toxic, fuming, or flammable media	Contained dispensing options	Reduces operator exposure and routes vapors away from the sampling point.
