ASPEC™ POSITIVE PRESSURE MANIFOLD
INTRODUCTION
Introduction
Description
The ASPEC® Positive Pressure Manifold provides uniform and consistent
flow rate control for the cleanup of low or high viscosity samples, improves
solid-phase extraction (SPE) reproducibility and recovery. The ASPEC® PPM
incorporates easily into laboratory workflows and provides a fast and simple
way to prepare several samples for later analysis by chromatography.
The ASPEC manifold offers a cost-effective approach to automation for
environmental, clinical, forensic, and food or beverage testing laboratories. It
is also an ideal choice for SPE cleanup prior to LCMS for bioanalyses.
