Regulatory Compliance
Thermo Fisher Scientific performs complete testing and evaluation of its products to ensure full compliance with applicable domestic and international regulations. When the system is delivered to you, it meets all pertinent electromagnetic compatibility (EMC) and safety standards as described in the next section or sections by product name.
Changes that you make to your system may void compliance with one or more of these EMC and safety standards. Changes to your system include replacing a part or adding components, options, or peripherals not specifically authorized and qualified by Thermo Fisher Scientific. To ensure continued compliance with EMC and safety standards, replacement parts and additional components, options, and peripherals must be ordered from Thermo Fisher Scientific or one of its authorized representatives.

Introduction

The LTQ XL/ETD and LTQ Velos/ETD systems are members of the Thermo Scientific family of mass spectrometer (MS) detectors, and consist of an ETD module installed at the back of an LTQ XL or LTQ Velos MS detector. With the LTQ XL/ETD or LTQ Velos/ETD system you can perform electron transfer dissociation (ETD) mass spectroscopy on analytes.
The LTQ XL and LTQ Velos MS detectors are advanced analytical instruments that include an atmospheric pressure ionization (API) source, a divert/inject valve, a linear ion trap, a syringe pump, and the Xcalibur data system.
The MS/ETD System is a source of fluoranthene reagent ions that react with analyte molecules in the linear ion trap of the LTQ XL or LTQ Velos MS detector. The ETD module contains two reagent vials, chemical ionization (CI)/carrier gas (nitrogen) handling hardware and flow restrictors, ion volume and filament, ion optics, and heaters for these components. The flow restrictors keep the internal pressure of the reagent vials below atmospheric pressure which prevents the contents of the reagent vials from being expelled into the laboratory atmosphere.
The nitrogen gas serves two functions in the ETD process. It is both a carrier gas and a CI vehicle. As a carrier gas, the nitrogen sweeps the reagent from the vial to the ion source where reagent radical anions are formed.
As a CI vehicle, the nitrogen gas collides with 70eV electrons from the filament in the ion volume. These 70eV electrons from the filament knock electrons from the nitrogen molecules, creating nitrogen ions. The secondary electrons resulting from these collisions have near thermal kinetic energies. The fluoranthene captures these thermal electrons to form reagent radical anions. The ETD optics transport the reagent radical anions to the linear ion trap where they react with the analyte.

Introduction

Electron Transfer Dissociation

Electron Transfer Dissociation
ETD provides peptide dissociation by transferring electrons to positively charged peptides, leading to a rich ladder of sequence ions derived from cleavage at the amide groups along the peptide backbone. Amino acid side chains and important modifications such as phosphorylation are left intact.

Types of Experiments

The New Method page of the Instrument Setup window for the LTQ XL (Figure 1) or LTQ Velos MS detector has buttons for the various types of experiment templates. Open the template for a particular experiment type, enter the parameters for the experiment, and then save the entries as part of an Xcalibur instrument method.

ETD Experiment Types

With the addition of the ETD module to the LTQ XL or LTQ Velos MS detector, two other experiment templates are available:
• Nth Order Double Play (ETD)—This experiment is useful as a survey experiment when you cannot determine whether the CID or ETD mode of dissociation works best. For example, CID works best for dissociating doubly-charged ions while ETD works best for ions of a higher charge state.
• Data Dependent NL MS dissociation might make it easier to identify sites of the neutral loss (modification). ETD dissociation is also useful when there are multiple sites of modification.
For additional information, see Chapter 6, “Running an Xcalibur Experiment by Using
ETD.”

Tuning and Calibration

Tune parameters are instrument parameters (for example, ETD optics) whose values can vary with the type of experiment or analyte being mass analyzed. Tuning the instrument on an analyte ensures sensitivity and mass resolution.
Calibration parameters are instrument parameters whose values do not vary with the type of experiment. You calibrate the mass spectrometer to ensure mass accuracy.
IMPORTANT Thermo Fisher Scientific recommends that you calibrate the mass spectrometer at least once every three months and that you check the calibration about once a week.
To tune and calibrate the LTQ XL/ETD or LTQ Velos/ETD system, perform these basic steps:
• Tune and calibrate the LTQ XL or LTQ Velos MS detector as described in the LTQ S eri es Getting Started Guide.

Introduction
Tuning and Calibration

Diagnostics

• Tune the optics in the ETD module as described in Chapter 3, “Tuning.”
To learn more about some of the diagnostic tools and tests, refer to the LTQ Series Getting Started Guide and the LTQ Series Hardware Manual. (At this time, not all diagnostic tools or tests are discussed in the product guides.)

Specifying the Reagent Ion Source for the MS Detector

Adding the MS Detector to the Xcalibur Instrument Configuration

To control the ETD source and the LTQ XL or LTQ Velos MS detector from the Xcalibur data system, add these devices to the Xcalibur instrument configuration.
To add the MS detector to the list of configured devices
1. Close the Xcalibur data system and Tune Plus application.
2. On the Windows taskbar, choose Start > Programs > Thermo Foundation 1.0 > Instrument Configuration (Figure 2).
Note For Xcalibur data system version 2.0.7 or earlier, choose Start > Programs > Xcalibur > Instrument Configuration.
