Instructions on how to fill the calibrant bottle in Agilent 6100 Series LC/MS Instruments when calibrant levels are running low.
The ability to autotune your Agilent LC/MS system relies on providing the instrument with the correct composition and concentration of calibration solution.
The type of Calibrant used for autotune depends on the type of Ion Source installed on your instrument
Steps to Follow
Caution: Some force may be required to start the unscrewing of the calibrant bottle. As the bottle is glass, aviod using excess force during removal that may damge the bottle or the bottle cap fixed to the instrument or cause injury. If the bottle cannot be removed easily then double check the calibrant is turned off in MassHunter and then contact your local Agilent service representative for further advice.
Ensure that the calibrant bottle is clean and uncontaminated before refilling the bottle with fresh tuning solution. The bottle can be cleaned using Ultrapure LC/MS Grade Water and an ionic detergent, then rinsed thoroughly with Ultrapure LC/MS Grade Water. Rinse the bottle a minimum of two times with Ultrapure LC/MS Grade Acetonitrile before being used.
Confirm the tuning mix that you are using to refill the calibrant bottle is correct for your Ion Source type, application, and mass range. Using the wrong type of tuning mix may cause contamination or will cause autotune failures.
Warning: Wear appropriate Personal Protective Equipment including suitable gloves and safety goggles when handling calibration solutions. See the MSDS supplied with the tuning solution for further details.
Refill the calibrant bottle about one-third full with the appropriate tuning mix depending on the ion source installed on the instrument (see the Items Required section). The level of solution should be a minimum of 2 cm above the end of the CDS intake tube. The tuning mix is used neat without any dilution steps.
Place the intake tube into the refilled calibrant bottle as you lift the calibrant bottle into position, then tighten the bottle in a clockwise direction, see Figure 2.
Caution: The bottle only needs to be snug. Do not overtighten the bottle, or you can cause the bottle cap to crack and leak. A leaky bottle cap can prevent the bottle from pressurizing and can lead to the evaporation of the contents.
In the Manual Tune tab, check the Calibrant on check box to repressurize the calibrant bottle. See Figure 3
