Page 6: Introduction
INTRODUCTION The ISO-H2S-100 is a hydrogen sulfide sensor with a 100µm diameter tip. It is a dry microsensors, however, it functions like a traditional ISO-H2S-2 sensor. The sensor can be ordered in a variety of lengths from 2–5mm. It incorporates WPI’s proprietary combination electrode technology in which the hydrogen sulfide-sensing element and separate reference electrode are encased within a single shielded sensor design. -

The Performance Evaluation included with your sensor shows the baseline current and the sensitivity of your sensor when it was quality tested at WPI. (In addition, it shows the polarization time of your sensor in the WPI labs.) The baseline value attainable in your lab may be slightly higher or lower, depending on the temperature* and composition of the test media. -
Page 9: Calibrating The Sensor
S stock solution should be maintained at the same temperature. NOTE: For additional information, refer to the free radical analyzer manual. Most WPI manuals can be downloaded directly from www.wpiinc.com. This information can also be e-mailed when you contact the WPI Technical Support team at 941.371.1003 or technicalsupport@wpiinc.com. - Page 10 Wait until the current on the display stabilizes again before continuing and record the value. This may take several minutes if the sensor has undergone a large temperature change. To the vial containing 20mL of PBS solution, sequentially inject four aliquots of the S solution (5µL, 10µL, 20µL and 40µL) into the glass vial.

If the sensor was used in a protein-rich solution, the tip should first be soaked in a protease solution for several minutes to remove protein build-up and then rinsed with distilled water. Enzymatic detergent (Enzol, WPI #7363-4) can also be used. The sensor can be sterilized chemically using an appropriate disinfectant (Cidex, WPI #7364). -
