Any biological agent that has died before the analysis has begun will not be detected. High flow rates are generally desirable because this allows higher sample volumes and increases the likelihood of detecting the suspect agents. They contain a series of tubes which can be used to detect airborne chemical agents, as well as toxic industrial chemicals. They can also be used in a dry or wet fashion.
This will include routine cleaning of the UV lamp using methanol and frequent replacement of the dust filter. Large, easy-to-read display Want to view data from across the room? Chapter 10 contains the discussion of noise monitoring equipment. Submicrometer particles are grown with alcohol or another liquid vapor as they pass through a heated saturator lined with alcohol-soaked felt.
Trypticase soy agar is normally used to collect bacteria, and malt extract agar is normally used to collect fungi. For example, benzene (IP 9.25 eV) can be detected with a 9.5 eV lamp, while methylene chloride (IP 11.35 eV) requires use of the 11.7 eV lamp. In general, higher energy lamps have a much shorter lifespan than lower energy lamps. Appendices B and C describe specialized tools used to evaluate chemical and biological warfare agents, respectively. The CTC serves as a source of technical information for instruments and measurement technology. Overcharging, by charging for too long a time period at a high charge rate, can damage the battery. Some interfering compounds can result in false positive readings. In other cases, the sensor can be damaged, or «poisoned» by exposure to certain compounds, in which case it will need to be returned to the CTC for sensor replacement.
