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 chip-scale ion-trap mass spectrometer driven by a monolithic photodiode array and a method of fabricating the same. A high-voltage photovoltaic source is located in proximity to the ion-trap mass spectrometer structure. The high-voltage photovoltaic source includes monolithically fabricated and serially connected photodiodes. An external light source illuminates the photodiodes to generate a high voltage across the photodiode array. An RF voltage modulation is attained by modulating the light source at a desired RF frequency. The high-voltage photodiode array may be monolithically fabricated in association with the ion-trap mass spectrometer. The photodiode array requires a small area compared to the ion-trap mass spectrometer size as the spectrometer typically possess a very small capacitance and a low power consumption.
