1. In areas containing these highly volatile compounds the filter can quickly become saturated In such situations it is recommended that these gases be allowed to dissipate before sampling for the less volatile more persistent mercury vapor In addition a special filter designed to remove chlorine gas from the sample stream is available from Arizona Instrument and may be ordered as Chlorine Filter AZI P N Z2600 3940 Collection of air samples with Jerome gold coil dosimeters for analysis by the J erome mercury vapor analyzers will also eliminate interferences Ammonia in very high concentrations can cause an off gassing of accumulated acidic fumes from the internal acidic gas filter resulting in positive readings on the instrument In these cases the ammonia odors are very strong A special filter designed to remove ammonia gas from the sample stream is available from Arizona Instrument and may be ordered as Ammonia Filter AZI P N 990 0193 Again either allow the vapors to dissipate use the ammonia filter or use the dosimeters Filter replacement at regular intervals or when unexpectedly high readings are encountered in areas of these potential interferences may resolve these problems Visit the Tech Notes section at www azic com for more information concerning the chlorine and ammonia filters Volatile mercury compounds in general will cause the gold film to respond Alkyl organic mercuries such as methyl mercury and ot
