4 ~ m Small particles which do not affect HPLC columns can affect UPLC columns Column lifetime can be reduced Pressure is higher and higher, column plugged Impurities (from solvent and sample) can be detected Bacterial growth can impact column lifetime 2012 Waters Corporation 7 ACQUITY UPLC Tips and Tricks Mobile Phase Preparation Always make sure that there are no insoluble particles in the eluents Nothing different from Use high quality solvents, buffers and additives. Organic solvents Usually High Grade organic solvents are filtered through a membrane (read the label on the bottle) JT Baker LC/MS Grade, Biosolve, Burdick & Jackson, Fisher Optima LC/MS Grade Water Milli-Q water is filtered through a m membrane (sterile) oBacterial contamination is a problem Milli-Q system, properly maintained Bottled water ?

5 2012 Waters Corporation 8 ACQUITY UPLC Tips and Tricks Mobile Phase Preparation Chemicals, reagents, powders Use high grade reagents Filter non volatile buffers ( m or m high quality membrane)! Use clean glassware (bottles and device for filtration) Who takes care of this ? How is it managed ? What is the quality of glass ? Is it compatible with the mobile phase (pH) ? Bottles must be capped, do not top-off the bottles Waters UPLC Media bottle kit (P/N EEE000394): High quality type 1 Class A borosilicate bottle kits One kit includes 7 bottles (4 x 1 l and 3 x 500 ml) All caps and pouring rings (colour coded)

10 Purge: pure water with 5% organic solvent (solvent in the sample syringe) Wash solvent (in the sample manager; SM-FTN): For washing the external part of the needle. Prevents carry-over Must dissolve samples and contaminants Sample diluent is appropriate Initial mobile phase strength is appropriate 2012 Waters Corporation 18 System Set Up What If You Would Like To Use A SM-FL ACQUITY UPLC and ACQUITY I-Class can be configured with a SM-FL FL: Fixed loop Same rules apply for solvents (eluents) lines and seal wash 2 Wash solvents (SM-FL): Strong wash (to prevent carry over.)
