The Ultra-Fine Metal Ion Analysis Chip (50 μm) is a microfluidic electrochemical sensor designed for trace metal detection and quantification in environmental and analytical applications. The chip features 50 x 40 μm microchannels optimized for high-sensitivity analysis of metal ions at ultra-low concentrations. Electrochemical detection provides direct, real-time measurement capabilities without requiring sample preconcentration or complex optical systems.
This microfluidic platform enables researchers to perform quantitative metal ion analysis with minimal sample volumes and reduced analysis time compared to traditional methods. The ultra-fine channel dimensions enhance mass transport efficiency and increase surface-to-volume ratios, improving detection sensitivity for trace-level measurements. The chip design accommodates standard microfluidic connectors and is compatible with common electrochemical measurement systems.
How It Works
The Ultra-Fine Metal Ion Analysis Chip operates on electrochemical detection principles, utilizing controlled potential techniques to selectively detect and quantify metal ions. Sample solution is introduced into the 50 x 40 μm microchannel where target metal ions interact with working electrodes integrated into the chip design. The electrochemical cell configuration enables voltammetric or amperometric measurements depending on the analytical protocol.
The ultra-fine channel dimensions create high surface-to-volume ratios that enhance mass transport of analytes to the electrode surface. This microfluidic environment promotes efficient mixing and reduces diffusion distances, resulting in improved signal-to-noise ratios and faster equilibration times. Metal ions undergo oxidation or reduction reactions at characteristic potentials, generating measurable current responses proportional to concentration.
Electrochemical stripping techniques can be employed for enhanced sensitivity, where metal ions are first preconcentrated at the electrode surface through controlled potential deposition, then stripped using potential scanning to generate amplified analytical signals.

Practical Tips
Use degassed electrolyte solutions to prevent bubble formation in the microchannels during analysis.
Why: Air bubbles can disrupt fluid flow and interfere with electrochemical measurements.
Perform calibration with standard solutions covering the expected concentration range of your samples.
Why: Electrochemical response may be non-linear at trace concentrations, requiring appropriate calibration curves.
Flush channels with clean electrolyte between analyses to prevent carryover and electrode fouling.
Why: Residual metal ions from previous samples can interfere with subsequent measurements and affect accuracy.
Allow sufficient equilibration time after sample introduction before recording measurements.
Why: The microfluidic environment requires time for complete sample exchange and electrode response stabilization.
If baseline drift occurs, perform electrode cleaning cycles in supporting electrolyte.
Why: Electrode surface contamination can cause unstable baselines and poor analytical precision.
Handle the chip carefully to avoid damage to the delicate microchannel structure.
Why: Ultra-fine channels are susceptible to blockage or structural damage from excessive pressure or mechanical stress.
