Article Title: Can Air Quality Gas Sensors Be Used for Emission Monitoring of Small-Scale Local Air Pollution Sources? Pilot Test Evaluation
Article Snippet: The used Alphasense sensors with dimension scale. (a) Assembled PID sensor and its components (sensor body, gas discharge lamp, and ionization chamber with electrode stack).

Article Title: Low-cost photoionization sensors as detectors in GC × GC systems designed for ambient VOC measurements.
Article Snippet: PID sensor performance for toxic chemical measurementswith an 11.7 eV argon lamp (le detect four species including ethane (ethoxymethythiol) (RT at 7.3 min), 2‐chloroet diethylethyl‐phosponate (RT at 9.2 min) whilst the PID with a 10.6 eV Krypton lamp can d Overlaid in both cases is the MS response. desorption unit, a temperature controller for GC columns, GC column holders for primary and secondary GC columns, PID sensor (Alphasense, PID-AH), power supply, compact RIO computer (cRIO, National Instruments), respectively.

Article Title: Design and Experiment of Fumigant Gas Trace Detection System Based on Photoionization
Article Snippet: To meet the requirements, based on the provision of Administration of Quality Supervision, Inspection and Quarantine(AQSIQ), of gas leakage monitoring inside dosing room of fumigant warehouse at the inspection and quarantine port, a fumigant gas trace detection system(FGTDS) based on photoionization detector(PID) is developed.. The principle, structure and characteristic of the system design are especially demonstrated.. The test data under different temperature, relative humidity(RH) and methyl bromide concentration demonstrate that the FGTDS based on PID can measure methyl bromide under very low concentration.

Article Title: Gas Sensor Array for Reliable Fire Detection
Article Snippet: .. More specifically, the customized sensor platform was composed of an 8-MOX gas sensor array (two units of AS-MLK, AS-MLC, AS-MLX, AS-MLN; provided by AMS, working at two different temperatures each sensor type), a PID sensor (PID-A1; Alphasense), a NDIR CO2 sensor (IRC-AT; Alphasense), a CO electrochemical sensor (CO-BF; Alphasense), and a temperature and humidity sensor (SHT75; Sensirion). ..

Article Title: Three-Dimensionally Printed Mini Air Scrubbing Cartridges Based on Nano-Graphite for Air Pollution Monitoring.
Article Snippet: .. As depicted in the scheme of Figure 5, it consisted of the following main parts: (a) Gas tight syringe (25 μL syringe by Hamilton), (b) mini DC pump connected to an air zero filter, generating the main air flux (fixed to a 300 mL/min), (c) “T-shape connector” with a sealed needle orifice for gas injection, (d) a sealed 3D printed cartridge accommodation, (e) PID sensor (PID-AH by Alphasense) accommodated into a suitable chamber, (f) two-way electro valves (V1 and V2) and (g) an electronic board, that controls the syringe surging and injecting volume, acquire the sensor signal and transmit the data to PC unit. .. In particular, we have paid more attention to the 3D cartridge accommodation that was made using a Teflon tube with the inner diameter equal to the cartridge diameter and to avoid any kind of flow losses, a polyimide sealing resin (23817 suitable for gas chromatography, by Supelco) was used to seal all the interstices between the cartridge and the inner tube surfaces (on the front and the bottom of the cartridge).
