If you are using the programmable Custom Assistant, and your data quality is
not ideal, try switching to the Classic Capture mode instead. Classic Capture
allows you to optimise each parameter yourself, so you can get the best
possible data out of every pore.
MITIGATING CONTRIBUTING FACTORS TO RMS NOISE
External/environmental noise
50/60 kHz noise from nearby laboratory equipment and ungrounded power
supplies can interfere with the baseline current signal.
To reduce influence from external noise, do not operate the qNano in close
proximity to large laboratory appliances that draw a lot of power, and ensure
the fluid cell cap is used during data recording to minimise noise on the
baseline current and obtain better blockade resolution.
Short-circuits
Electrolyte can creep in between metal connection points inside or around the
fluid cell, causing significant noise fluctuations.
Remove the upper fluid cell, then wash and dry it, making sure all the
metal parts of the fluid cell and fluid cell cap are dry. Then re-establish the
baseline current.
Always ensure that you are using the reverse-pipetting technique when
introducing fluid to the upper or lower fluid cells, and do not pipette more
than 35 µL into the upper fluid cell, or more than 75 µL into the lower fluid
cell, or the fluid may leak between connection points and cause the noise to
gradually increase.
