The probe is best prepared with these steps:
- Make sure the liquid has been filtered through maximum 0.2µm pores size.
Use the a 1µl pipette to slowly aspirate 0.2 to 1µl of the solution to be used and wipe the tip to avoid contamination outside the reservoir.
Insert the pipette tip until the bottom of the reservoir is reached and slowly eject the liquid there.
- Place the probe into the probeholder and pick up probe a.s.a.p. to avoid evaporation of the liquid.
Be careful to keep the upper border of the reservoir clean. Any presence of liquid may be deposited on the sealing screw. This could lead to cross contamination and air tightness failure. In case of head nose contamination, please refer to the maintenance section for head nose cleaning instructions.
