FloPro-ChemStack Analyzer

FloPro flow-based analyzer with fully integrated monolithic fluidics manifold.


ChemStackGlobal FIA is developing the expertise to capture complex flow manifolds in a transparent monolithic block.  Channels as small as 0.7 mm (.030”) ID are comfortably accommodated and because these channels are printed rather than machined, new possibilities with regard to channel and manifold geometry are possible.

In the FloPro-ChemStack, we mounted our ChemStack manifold on a Valco multi position valve.  We equipped the ChemStack with a heated holding coil, pressure transducer and pressure relief valve.  Ports are provided to accommodate an external unit operation such as an enrichment column, digester or solid phase reactor.  The spectrophotometric absorbance flow cell has a 20 mm path length.  The sample port allows priming of the sample without drawing sample into the holding coil.  Provision is made for up to six reagents, standards, blanks or wash solution.  The 5mL reagent vials are directly coupled to the ChemStack.  Off Stack reagent reservoirs are also possible.

The following diagram describes the ChemStack flow manifold.


The ChemStack manifold is available as a standalone accesory

Global FIA Products


In the early days of FIA, the most fertile repository of manifold components was the Chromatographer's laboratory.  Since those early days, a whole suite of custom components have been developed for those practicing flow-based analysis.  These components are now available commercially as stocked items.  Global FIA provides a single source for many of the components needed to equip and maintain a flow-based analysis laboratory.

The range of components offered includes:

  • Pumps - milliGAT™, syringe, and others
  • Valves - selection, injection, and others
  • Tubing - PFA, PEEK, Tygon™, Pharmed™, and others
  • Fittings
  • Adapters
  • Heaters
  • Reservoirs and vials
  • Gas diffusion and permeation devices
  • Solvent extraction components
  • Mini-columns and separation cells
  • Bead handling devices
  • Flow meters, low dead-volume temperature and pressure meters
  • A wide range of flow cells (included heated flow cells) and detectors such as photometric (uv and vis), chemiluminescence, fluorescence, amperometric, and potentiometric devices.

In recent years we have added a number of sampling components as well.  These include:

  • the unique supported capillary membrane sampler (SCMS)
  • self-cleaning filters
  • sampling probes for sampling slurries, and other heterogeneous samples
  • sterile sample probes
  • inertia filters also called tangential flow filters

All of these devices are available in the Global FIA store.
