Webwas detected by eight ionisation probes situated along the tube. Probe No. 1 was approximately 50 cm from the ignition end, probes 2 to 8 were situated from 120 cm to 520 cm from the ignition end, the spacing between the probes increasing from probe 2 onwards. They were supplied via 1 MΩ. resistors with 170 V from a stabilised supply. WebThe HESI-II probe is already standard on many Thermo Scientific mass spectrometers. Efficiently handles flow rates higher than 1 mL/min while maintaining superior flow rate characteristics with optimal use of gas-assisted thermal desolvation. Cleaner nozzle profile improves electrostatic fields; a single probe position works for most flow rates.
