Q: How do I install the silica gel (dessicant) or charcoal filter?
A: Remove the rubber boot. Open the back case on the Cyranose® by pushing the blue tab up on the backing. Notice the round, yellow filter bypass with 2 screws. Remove the screws with a Phillips screwdriver. Replace ONLY the plastic filter bypass with the filter of your choice. Make sure that the black o-ring is left in place. Replace the 2 screws. Ensure a tight fit but do not overtighten. After installing the filter, perform a leak test by measuring the flow rate at the purge inlet and exhaust. The 2 flow rates should be similar although they may not be identical.

Q: How long do the charcoal filters last before they need to be replaced?
A: As with using a dessicant filter, the lifetime of a charcoal filter varies with ambient conditions. For example, the dessicant filter will last longer in a dry room, like a lab, than in a very humid room, like a greenhouse. Likewise, the charcoal filter will last longer in a room with little odor, than in a warehouse where diesel trucks are constantly driving in and out. Unfortunately the charcoal filter doesn't have a color indicator like the dessicant. In a room with "normal" odor, a charcoal filter can last up to 3 months. (or longer depending on how often the device is used). In very smelly rooms, we have customers that decide to change the filter every week or every day. For a more analytical way of determining filter lifetime in a specific situation: 1) Sniff air several times without the filter. There should be little or no response. 2) Use clean charcoal filter. Sniff air several times. If the filter is working you should see a response. 3) Normalize the air sniffs done with the filter by summing the 32 responses for one sample. Then divide each of the 32 responses by the sum. (Easiest to do in Excel) 3) Repeat 2 and 3 regularly (daily, every other day, or weekly) and compare the NORMALIZED results. As the filter begins to function less effectively, you should see the responses decrease consistently. Be cautious in analysis because one day may be less smelly so your responses will be smaller as a result of ambient conditions not filter efficiency. Still have questions? Call us at .

Q: Can the Cyranose® 320 be used to detect chemical or biological warfare agents?
A: Testing is currently underway to confirm the Cyranose® 320's ability to detect chemical warfare agents and anthrax. The estimated detection limits of the Cyranose® 320 fall within JCAD specifications for various blood, blister and nerve agents. Previous work with bacteria indicates that the Cyranose® 320's has the ability to discriminate between different bacteria. For further information, please contact Cyrano Sciences at or .

Q: How should I determine the setting for the sensor temperature?
A: The sensor temperature should be set 7C above ambient temperature if you are using the Cyranose® 320 intermittently. However, if you are using the Cyranose® 320 continuously, set the sensor temperature to 12C above ambient temperature.
