To clean the capillary
To clean the capillary
When required When you observe decreased sensitivity and decreased signal stability
Tools required • 5190-1401 Cleaning Powder, Dielectric Capillary
• 100mL polypropylene graduated cylinder, or glass-graduated cylinder with
two 1 mL pipette tip
Parts required Powdered Precision Cleaner (Alconox catalog number 1104)
1 Dissolve 1 g Alconox Powdered Precision Cleaner in 100 mL deionized
water.
This concentration is the recommended concentration for “manual or
ultrasonic cleaning”.
2 Place the ion transport capillary upright in a 100 mL polypropylene
graduated cylinder and fill with Alconox solution.
3 Sonicate the graduated cylinder with the ion transport capillary in an
ultrasonic cleaner for 10 to 15 minutes.
You may use a 1 mL pipette over the end of the ion transport capillary to
protect the metallized plating. Trim the pipette tip to approximately 4 cm so
that the capillary can be immersed in the cleaning solution.
