Zero-drift AP Series Products
We’ve developed a proprietary coating for oxygen sensing in biological environments that has zero drift from photo-bleaching in long-term exposure.
The AP Series of zero-drift oxygen sensors come in different probe and patch form factors.
Applications
- Process control
- Environmental monitoring
- In-line monitoring in the beverage industry
- Wastewater treatment
- Long-term measurements in soil
| AP (Zero Drift) | HCR Hydrocarbon Grade) | MR (Sol Gel) |
|---|---|---|
| Zero Drift, No moisture interference, highly stable | Hydrocarbon compatible (fuels, organic solvent, alcohols) | Sol gel matrix, moisture resistant, high temperature performance, medical applications |
| Optical Sensors | Commercial Electrodes |
|---|---|
| Low maintenance | High maintenance |
| Life span of at least 1 year | The general electrode's life span is around 3 months |
| O2 sensors do not consume oxygen, which makes continuous contact with samples possible | O2 electrodes consume oxygen at rates of ~0.1 micrograms/hour |
| Immune to salinity, pH, and ionic strength changes of environment | Salinity, pH change, and ionic strength all have the ability to affect the electrode |
| Simpler and less frequent calibration | Hourly recalibrations can be required for electrodes |
| Sensor coating formulations are offered for a wide range of environments | Electrodes are generally not compatible with various chemicals |
| Optical sensors are highly specific and are not affected by chemicals imposed by environment such as CO2, organics, moisture, etc.. | Interference from various chemicals and sampling conditions is commonly experienced |
| Ease of production enables manufacturing flexible sensor form factors such as probes, patches, cuvettes, etc.. | Generally, electrodes are solely offered in probe or cell membrane format |
| Sensor transducers can be applied on flexible patches and placed inside biological reactors for non-invasive optical measurements | Electrodes normally do not lend themselves to non-invasive measurements |
