Needle-Type pH Microsensor
Needle-type pH Microsensors are the perfect tool for measuring in small volumes and for implementation into a variety of tissues. The protective housing enables a manifold of applications. The design is optimal for easy penetration of tissue, septum rubber or packaging materials. After penetration the sensor tip is extended for measurement.
Implantable pH Microsensor
Implantable probes are the miniaturized pH sensors designed for various customized applications. The tiny probe has a tip size of 150 µm while the outer diameter ranges from 140 µm to 900 µm.
The microsensor tip is not mounted in any additional housing. The bare glass fiber tip can be mounted to your own housings, steel tubes, catheters, etc. As the probe is free of metal, it can be used in the presence of high electromagnetical fields and even NMR environment.
Measurement Principle
The Patented Dual Lifetime Referenced (DLR) Method
The patented DLR method enables internally referenced measurements. A combination of different fluorescent dyes detects intensity changes in the time domain. It is essential for the pre-calibrated measurements and the easy parallelisation of measurement through the identical calibration of large numbers of sensor spots.
