Zone Fluidics Analysis

Zone Fluidics (ZF) is a powerful and flexible technology for automating sample preparation and analysis using microfluidic-based robotics. At the core of the system are the SmoothFlow Pump which provides pulseless bi-directional delivery of samples, standards and reagents and stream selection valves to direct the fluids to the appropriate Unit Operation. A Unit Operation is any device used to process samples in-line including heaters, UV digestors, micro-distillers, solvent extractors (liquid-liquid or solid phase), ion exchangers and detectors.

Microfluidica provides both application-based (see Products tab) and customized solutions using zone fluidics technology for both laboratory and process applications. In addition, experimental platforms are available for research and teaching labs.

MobiChem Mobile Chemistry Analyzer

MobiChem is specifically designed for small and properly equipped mobile laboratories for automating sample preparation and analysis of chemical species in waters.  Sample types include drinking water, waste water, ground water, surface waters and storm run-off waters.

Sample Preparation

MobiChem automates several complex in-line sample preparation procedures including:

• Digestion
• Dilution
• Distillation
• Extraction
• Gas diffusion
• Calibration standards preparation

Once prepared, MobiChem then processes standards and samples using the appropriate chemical analysis method for species including ammonia, chloride, total cyanide, nitrate, nitrite, total nitrogen, total phenol, ortho-phosphate, total phosphorus and surfactants.

Based on the technology of Zone Fluidics, MobiChem enables very flexible and complex sample processing to occur.  Each sample is treated discretely with complete inter-sample washout to prevent any carryover or cross-contamination to maximize accuracy and precision.

SmoothFlow Microfluidic Pumps

Whether you’re pumping liquids or gases, SmoothFlow Microfluidic Pumps provide positive displacement, self-priming and pulseless fluid delivery from nL to mL.  SmoothFlow has application in dosing, bi-directional pumping, continuous flow and stopped flow modes of operation.

Dosing (Metering)
Adding critical components to  mixtures requires both accuracy and precision.  SmoothFlow provides both consistently with automatic backlash compensation when starting and stopping.

Bi-Directional Pumping
Aspirating and dispensing are fundamental components of liquid handling.  Interfaced with the XYZ Autosampler/Fraction Collector, SmoothFlow can manipulate samples, diluents and reagents on the compact (~1 cubic foot) XYZ platform.  The combined XYZ/SmoothFlow devices can also prepare samples prior to introduction into an instrument such as a GC or LC or it can collect a prepared fraction for later processing.

Continuous and Stopped Flow
For analytical applications where continuous or stopped flow is required such as flow injection, segmented flow, sequential injection or zone fluidics analysis, SmoothFlow’s pulseless fluid delivery against a head pressure of up to 100 psi ensures accurate and precise analyte derivatization and measurement.
