Info

LCQ Recommended Maintenance Schedule Monthly: Every Month: ◗ Check the helium gas tank pressure. Replace as needed. ◗ Check the nitrogen gas tank (Dewer) pressure. Replace as needed. ◗ Nitrogen gas consumption: – Typical: 3-6 L/min – Worse case scenario associated with choice of Nitrogen Generator: 15L/min (28SCFH at 100psi and 99% purity) for LCQ Classic 30L/min (56SCFH at 100psi and 99% purity) for Duo / Deca ◗ Check the LCQ calibration. ◗ Check the air filter. Clean if necessary. ◗ Possibly, change the mech. pump oil.
LCQ Recommended Maintenance Schedule Every 3 months: Change the mech. pump oil. 6 months to a year: Change the turbo pump oil. Notes - The API stack and analyzer should be clean as needed. - If the sensitivity starts to drop off and can not be restored, clean the API stack (and analyzer) as needed.
