2 Application Setup

2.1 General Recommendations for Applications

The experimental conditions for each application are presented together with related information such as schematics, installation tips and examples, results and interpretation.

2.1.1 Connections

All high-pressure fittings used in the applications on the UltiMate 3000 RSLCnano system are made with nanoViper. nanoViper is a fingertight high-pressure fitting that is dead volume free by design and back pressure resistant up to 1000 bar. The fittings are assembled in the factory to ensure consistent fittings and prevent experimental failure due to bad connections.
Figure 1: Example of a nanoViper fitting
1. Install nanoViper as any fingertight fitting.
2. Do not over-tighten connections (general guide line: finger-tight + maximum an additional one eighth-turn).
3. Remove the black knurled screw.
The outlet of the nano columns is fitted with a nano connector. This is a dedicated connection designed to offer maximum flexibility in connecting fused silica capillaries and offering pressure stability up to 300 bars. The nano connector uses a special sleeve to ensure pressure tightness. The assembly of a nano connector is described step by step below.
Figure 2: nano connector layout
Use a new nano connector sleeve (P/N 6720.0391) for each connection
Important: Do NOT use a PTFE sleeve. The size does not match the nano
connector and the pressure resistance is much lower.

PTFE (1.8 cm)
Figure 3: nano connector (top) and PTFE (bottom) sleeve comparison
1. Slide the golden nut and silver union onto one of the fused silica outlets; slide the second golden union on the other fused silica end. ( Figure 4a and Figure 4b)
2. Slide the nano connector sleeve onto the fused silica, slide the other end of the fused silica into the nano connector sleeve and make sure the connection is dead volume free. Figure 4c
3. Tighten the golden nuts equally fingertight to ensure the nano connector sleeve is centered in the silver union. Figure 4d

2.1.2 Sample Preparation

Follow the instructions provided with the test sample and use the solvents as indicated.
After re-dissolving the sample wait at least 15 min before further diluting it.
o Use water with a minimum of 2 % ACN and appropriate ion-pairing agent to
dissolve.
o Dilution can be done in the same solvent or with water with appropriate ion-pairing
agent.
Tip: To limit the risks of peptides or proteins adsorption on the walls of the vials,
Thermo Fischer Scientific recommends using glass inserts (Polypropylene vials for WPS with glass insert, 250 µL, set of 25, P/N 6820.0027).
Tip: When using IEX columns, make sure that the sample solvent contains a very
limited amount of salt and is at the right pH level (for example, adjust to pH 3 when using a SCX column to separate peptides).
7
UltiMate 3000 RSLCnano – Standard Applications

2.1.3 Mobile Phases

Always use fresh solvents.
When running online multidimensional approaches, make sure that the mobile phase of
the first dimension will allow for trapping the sample on the (trap) column used on the second dimension.
For example, do not use phosphate buffers from SCX separations as loading solvent in
RP separations.
Thermo Fischer Scientific recommends replacing (aqueous) solvents at least once every
two weeks.
Tip: Replace solvents completely; do not ’top up’ to avoid unwanted components
building up in the mobile phases.

2.4.3 Installation Tips

Follow the General Recommendations for Applications ( page 6).
The impact of dwell (dead) volumes on reproducibility is very important. Improper
connections of the different elements are the most likely cause of failure for this application.

2.4.4 Testing the Application

The direct injection can be tested using the following conditions:
Property Setting
Mobile phase A 100% water + 0.05% TFA
Mobile phase B 20%/80% (v/v) water/ACN + 0.04% TFA
Sample Cytochrome C digest 1 pmol/μL, prepared according to the instruction sheet
Injection volume 1 μL
UV detection 214 nm
Gradient 4% to 55% B in 30 min
90% B for 5 min
25 min equilibration
WPS temperature
Flow rate 300 nL/min (nano flow selector)
5°C (WPS-3000(B)T only)

For details on interpretation and troubleshooting of the Cytochrome C nano LC separation, see the FAQ section on page 50.

2.4.5 Large Volume Injections

Typically direct injections in nano LC are performed with 1 µL loop sizes to minimize the gradient delay. Larger volume injections are performed with a pre-concentration setup. The WPS-3000PL autosampler series allows for a custom injection program (UDP) to switch back the injection valve after sample loading to bypass the loop. This way a larger sample volume can be injected and pre-concentrated directly onto the nano column, without using a pre­concentration setup.
16
UltiMate 3000 RSLCnano – Standard Applications
The advantage of such a setup is the ease of use and a minimum loss of peptides, especially hydrophilic ones. The prerequisites of this setup are desalted samples, since all that is injected will enter the MS, and an investment of extra analysis time to accommodate the loading of sample with nano flow.
