Variable Pressure Sampler (VPS) en Fort Collins, Colorado, USA

In gas chromatography (GC), maintaining consistent sample injection pressure is critical to achieving precise, repeatable results. Variations in sample pressure or flow during injection can introduce error in calibration and measurement especially for trace-level and multi-component gas mixtures.
The Wasson-ECE Variable Pressure Sampler (VPS) solves this problem by actively controlling and equalizing sample and calibration gas pressures, ensuring that every sample is injected at a uniform, reproducible pressure. It also enables the creation of multi-point calibration curves from a single standard, reducing cost and improving method development efficiency.
Qualification
Developed by Wasson-ECE Instrumentation, a leader in custom analytical systems for Agilent Technologies GCs, the VPS builds on decades of expertise in chromatographic precision and process analysis.
