摘要： A method includes acquiring a chemical sample and modulating the chemical sample at a frequency greater than a drift frequency of a sensor. The method also includes determining at least one of a presence and a concentration of the analyte within the modulated chemical sample using the sensor. Modulating the chemical sample could include alternately absorbing at least some of the analyte into a sorbent material and releasing at least some of the analyte from the sorbent material. Modulating the chemical sample could also include heating the sorbent material, absorbing part of the analyte into the sorbent material, and passing a remaining portion of the analyte into the sensor. Modulating the chemical sample could further include stopping the heating of the sorbent material, releasing the part of the analyte from the sorbent material, and passing the sample with the released part of the analyte into the sensor.

摘要： A micro discharge device (MDD) capable of low voltage discharges in a variety of carrier gases for detection and/or ionization includes a sample introduction capillary having a first open end connected to a gas system and a second open end connected to a cylinder comprising a high dielectric constant material. A high voltage electrode can be placed in close proximity to the outer diameter of the cylinder and at a close linear distance to the second open end of the sample introduction capillary. A region can be formed inside the cylinder between the second end of the sample introduction capillary and the high voltage electrode wherein discharge can be located. An optical emission collector can be located through the flow manifold to a receiving location near the high voltage electrode within a region from inside the cylinder between the high voltage electrode and the manifold.
