ultima posizione

posizione data evento Desrizione
in osservatorio

MPSS installed, the CPC used is now the TSI_3772, previously used as totCPC.

Sheathflow pump installed as compressed air, not in vacuum (as it was before), following WCCAP suggestion. Flow 4.8L/min (ambient)
HV voltage calibration:

  • 0.4mV:
    • from -0.0039 (1.8v)
    • to -0.0016 (5.2V)
  • 800mV:
    • 0.789 oscillating a bit between 996V to 1002V
  • 200mV:
    • 249V

PSL cal, sheath flow slope re-adjusted from 1.3 (peak 196nm) to 1.2 (peak 200nm)

Back to UTC time (UTC+2 used while at WCCAP)

Measurment mode ON

Next step: grounding DMA

removed for WCCAP calibration/intercomparison Marinoni Angela
Firnware update, APS connection, HV calibration Marinoni Angela

New version of scan software installed (Scan_80).

APS installed and communicate with SMPS laptop (settings: correlated --> summed, Scan single, Baud rate: 9600)
HV calibration solved the problem of the limitation of the first three channels)

 
PSL check Marinoni Angela

PSL 20onm in MIlliQ water, nebulized with pari compact.
Peak seen at 199 nm. Picture attached
