    OVERVIEW WARNING Unisense MicroOptodes are neither intended This manual covers all the Unisense MicroOptodes . The nor approved for MicroOptode relies on the latest developments within optical fiber use on humans technology utilizing near infrared dyes for improved performance, high precision, high reliability, low cross-interference and fast response times .

  • Page 10: Getting Started

    Remember that a temperature sensor is required for correct oxygen measurements unless the measurement and calibration is completed at stable temperature . xygen Saturated Solution Place the MicroOptode in a well-aerated calibration solution (e .g . by bubbling with air in the Unisense calibration chamber) .

Zero reading ero reading An anoxic solution can be prepared in one of several ways; below we describe two methods recommended by Unisense: 1 . Prepare a solution of sodium ascorbate and NaOH, both to final concentrations of IMPORTANT 0 .1M (~2 g sodium ascorbate in 100 ml of...

    . ounting of the icro ptode When the optical fiber is exposed Unisense recommends mounting the MicroOptode in a stabilized setup using the Unisense lab stand (LS18) and micromanipulator (MM33, MM33-2) to avoid damages on the MicroOptode .

  • Page 14: I Nterference

    nterference The oxygen sensitive dye on the optic fiber shows excellent brightness and their red light excitation significantly reduces stress in biological systems and interferences caused by autofluores- cence . The MicroOptodes can be applied in gas phases, aqueous solutions, ethanol, methanol and isopropanol . Other organic solvents and gaseous chlorine (Cl ) induce interferences with the sensor reading .
