SYSTEM FOR REMOTE COLLECTION AND ANALYSIS OF AIR SAMPLES FROM SURFACES AND FROM UNSEALED OBJECTS Russian patent published in 2010 - IPC G01N1/22 

FIELD: chemistry.

SUBSTANCE: system has a device for blowing an object with an air jet, which has a blown air stream activator and a device for sucking the air stream coming from the object which is fitted with a sucked air stream activator. The sucking device is made in form of a suction duct whose outlet is connected to the sucked air stream activator, and the inlet lies inside the device for blowing the object and is fitted in line with the device. The blowing device is fitted with an air stream swirler and channel carrying the blown air stream from the activator to the swirler. The swirler is made in form of a reflector and a fixed blade mounted near its base and in line with it, which forms an annular cavity with the suction duct, which is the outlet of the channel carrying the blown air stream. At least a reversible air pump is used as the sucked air stream activator. Between the sucked air stream activator and the suction duct there is a device for collecting and analysing a sample in the air stream coming from the object, which includes at least apparatus for heating the air stream coming from the object and which is connected by the inlet and outlet of the gas channels to the suction duct and the sucked air stream activator, respectively.

EFFECT: more efficient system and elimination of the memory effect during analysis.
