nanoACQUITY UPLC Column Care and Use

2

I. PreParIng eluents

Do not filter solvents. Use MS grade solvents directly from the bottle

A solvent: 100% water with 0.1% formic acid

B solvent: 100% acetonitrile or methanol with 0.1% formic acid

Seal wash solvent: water, may contain small amount of

organic (no acid)

Weak needle wash for peptides: 3% acetonitrile with 0.1% formic acid

Note:

Good lab practices: no solvent bottles to go through the dishwasher!

Wear gloves when handling solvent lines and hardware

If system is contaminated with poor quality solvents,

flush with appropriate solvent

Many report successful use of solution containing 25% water,

25% acetonitrile, 25% methanol, 25% IPA and 0.1% formic acid

For PEG contaminated, try IPA

DO NOT USE strong bases, as they can strip fused silica

Where to source solvents:

In North America: Fisher Optima or Burdick & Jackson

In Europe: Biosolve (Netherlands) provide very good solvents.

They offer smaller bottles (0.5 L) as well as "UPLC" grade solvents.

II. PreParIng samPle

Samples for expression analysis must contain tryptic peptides derived

from proteins of interest at suitable concentrations

Samples may contain buffers and residual reagents from approved

digestion procedure

The sample must not contain other reagents, denaturants, detergents,

lipids, and must be free of particulates.

III. PreParIng and ConneCtIng 75, 100 or
150 µm nanoaCQuIt Y Columns

A: PREPARATION

Carefully remove your column from bag.

The gold ferrule on the inlet of the column is placed snugly on the

tubing at the factory. The ferrule is lightly secured to reduce the risk of
it being lost as the column is removed from the packaging. The ferrule
is purposely set high on the tubing but will properly seat itself in the
correct position upon tightening.

A small piece of Teflon

®

tubing is present on the outlet end of the

column for those who want to connect the device to a UV or PDA
detector rather than a mass spectrometer.

Note: The column is attached to a transfer tube with the use of a
zero dead volume union. This is hidden beneath the heat shrink
tubing. Care must be taken NOT to excerpt force on the ends of the
nano column (e.g., when removing teflon tubing at column outlet)
that could cause this joint to separate.
