Eject the sample carefully, forceful ejection can damage the plunger seal.
Do not dose volumes smaller than 10% of the total syringe volume (no less than 10µl with an 100µl syringe).
Perform cleaning procedures often. However, some of the substances will always remain in the needle.
Ease of movement
Reduce the force necessary for movement by heating or cooling, as shown in the video tutorial on our website.
Do not draw up the syringe too quickly. Draw the syringe slowly or use a needle with bigger I.D.
Adjust the autosampler cycle for best results.
Releasing air bubbles
Quick injection moves the air bubbles. Overfill the syringe, turn it upside down (needle up), allow the bubbles to move upwards and then eject.
