Flow sensor NTH-PSt1

oxygenlaboratoryminiature

This sensor is a miniaturized optical oxygen sensor designed for all research and packaging applications where a small tip size (< 50 µm tapered sensor tip TS, < 140 μm flat-broken sensor tip TF) and fast response time (t90 < 3 s) are necessary. It is mounted inside a stainless steel needle, which protects the optical fiber and oxygen-sensitive sensor tip. This design is optimal for easy penetration of tissue, septum rubber or packaging materials. After penetration the sensor tip is extended for measurements. High spatial resolution (down to < 50 μm) High temporal resolution (t90 < 3 sec.) No consumption of oxygen Signal independent of flow velocity Measures in liquids as well as in gas phase APPLICATIONS Packaging & Quality Control Oxygen inside packaging can lead to oxidative deterioration of certain products. Therefore, determination of the oxygen content within packages or pharmaceutical vials is of essential importance to ensure both the filling quality and the long-term storage stability. With our micro-invasive needle-type oxygen microsensors we offer a simple tool to determine residual oxygen both in the headspace and in liquids. The septum of the vial or package is pierced with the needle and the sensor is extended for measurement. As the measurement is made inside the package no error-prone and time consuming sampling is necessary. These oxygen microsensors are ideal tools for quality control in the food & beverage, packaging, and pharmaceutical industries.
