Water Soluble Oxygen Sensor

To the best of our knowledge this is the first practical water soluble oxygen sensor.

Water soluble oxygen sensor.

The optimum oxygen sensor film composition was 2 in 1 1 silamine mc which had an oxygen sensitivity of 0 502 over an atmospheric pressure range of 0 007 45 psi. 30 apera instruments optical dissolved oxygen meters 4 price 92. Because the sensor concentration would not be important the sensor could be added using a simple dropper bottle. We developed a water soluble luminescent probe for dissolved oxygen.

The absorption maximum near 480 nm long lifetime and large stokes shift allow this probe to be used with simple instrumentation based on a light emitting diode light source allowing low cost oxygen sensing in aqueous solutions. Use of water soluble oxygen sensors to study the oxygen consumption during photosensitization with hypericin in vitro and in vivo conference paper in biophysical journal 110 3 507a 508a. This probe is based on ru dpp so3na 2 3 cl2 which is a sulfonated analogue of the well known oxygen probe ru dpp 3 cl2. The do30g sensor for dissolved oxygen is designed for use in water treatment plants such as sewage treatment works effluent activated sludge process and potable water treatment.

39 hach 146900 dissolved oxygen test kit model ox 2p. A dissolved oxygen meter water quality sonde or data logging system can be used to record measurement data taken with a do sensor. Temperature sensitivity percentage loss of intensity per c of this film was determined to be 1 1 and 1 4 c 1 at vacuum and 1 bar atmospheric pressure respectively. For instance water samples could be mixed with small amounts of a water soluble sensor and the oxygen concentration determined from the intensity or preferably the decay time which would be insensitive to the probe concentration.

The compound dpp is 4 7 diphenyl 1 10 phenanthroline and dpp so3na 2 is a disulfonated derivative of the same ligand. Here we report on the pl properties of water soluble cdte ncs with 3 mercaptopropionic acid as the ligand showing that these ncs are capable of responding reversibly to an inter switching of the. It is also effective in river monitoring intake protection fish farming and other fields where water quality is important. The procedure of metalloporphyrins immobilization.
