Sampling System
Sampling System
We rely on analyzer results to confirm product quality, but when those results are off, the problem often lies in the sampling system. In fact, around 80% of analyzer issues are caused by poor sampling system design or performance.
6 main goals of process analysis ensure accurate, efficient, and safe sampling:
- Compatible: Ensuring the sample is chemically suited for the analyzer prevents errors and guarantees valid data.
- Timely: Fast results allow operators to react effectively.
- Representative: The sample must mirror actual process conditions.
- Reliable: Consistently available results strengthen decision-making and process control.
- Cost-Effective: Efficiency and reduced operating costs.
- Safe: Protecting personnel, equipment, and the environment.
Sampling Conditioning System
Accurate analysis starts with the right sample. Since process analyzers cannot always accept samples directly from the process tap, a sample conditioning system is essential. It ensures the sample truly represents the process, is delivered in a timely manner, and is fully compatible with the analyzer. By controlling pressure, temperature, and flow, the system protects your analyzer from process anomalies—helping you achieve reliable performance and consistent results.
Sample Probe Module (SPM)
Sample Probe Module Application Guide
Using sample probe modules in conjunction with sample probe valves (SPV) can improve safety as well as sample purity and timeliness. A probe provides a faster analyzer response by reducing the volume of the sample system. The nozzle volume can be significant, increasing the required purge volume of the entire sample system. Also, the probe allows the sample to be extracted from the centre of the process pipe, which eliminates the extraction of sludge along the pipe walls.
Fast Loop Module (FLM)
Fast Loop Module Application Guide
Fast loop modules are designed to handle high flows in sample transport lines to reduce time delays for online analyzer systems. Located at the analyzer shelter and offering a bypass, the FLM can isolate the sample system and introduce a purge gas for system cleaning. The FLM from Swagelok extracts a sample through a filter while using the high flow rate of the bypass to keep the filter element clean.
Calibration Switching Module (CSM)
Calibration Switching Module Application Guide
Swagelok® Calibration and Switching Module, also known as the Sampling Conditioning System, is available in a modular design. The CSM allows the user to select the configuration required for a specific system, and this pre-engineered sub-system gives the user freedom in terms of room since it has a compact footprint and can save about 50% space compared to a conventional Sampling Conditioning System.
The main function of the CSM is to condition and select process streams or to select a calibration stream for analysis. At a minimum, each system must have two inlets: two process stream inlets or one process stream inlet and one calibration stream inlet. The signal opens one of the Stream Selector System (SSV series) double block-and-bleed valve modules corresponding to the stream containing the fluid to be analyzed, which is usually installed in the Modular Platform Component (MPC). The selected fluid flows through the CSM to the process analyzer.
- Modular Platform Component (MPC)
The MPC system is a system for use within process analyzer, sample-handling, and fluid distribution systems. Swagelok MPC system includes a complete selection of MPC series components, and a complementary configuration tool called the MPC System Configurator.
An MPC series assembly provides a compact fluid-distribution system with a reduced footprint for efficient use of component space. Modular technology allows the user to customize each system for a specific application and reduces installation and maintenance time. Surface-mount components include valves, filters, flowmeters, regulators, pressure gauges, and digital pressure-temperature transducers. It can be serviced easily from the top of the assembly without disturbing any other components.
- Stream Selector Valve (SSV)
Stream Selector System (SSV series) is a modular assembly designed for process analyzer sampling systems. SSV series system can accommodate multiple process streams with each stream controlled by a DBB module. Each DBB module features a double block-and-bleed design to eliminate cross-contamination of sample streams.
The SSV will help reduce the number of analyzers used if a few streams can be analyzed using only one analyzer instead of using a few analyzers for few streams. It will help to minimize the overall cost for sampling system since one sampling conditioning system only costs approximately 30% smaller than the analyzer’s price. This pre-engineered sub-system gives you freedom in terms of room since this is a compact footprint and can save about 50% space compared to a conventional sampling conditioning system.
