Nano Spray Source
Why Use This Source?
The NanoSpray source extends the versatility of the QSTAR ion source techniques to allow lower sample flow rates with high sensitivity for
automated capillary LC/MS/MS applications using the Continuons NanoSprayTM and MicroIonSpray") heads.
In nanospray applications, an electrical potential is applied to the sample as it passes through a stainless steel union and then into a fine-tipped emitter needle. The sample is ionized by ion evaporation, and the resulting ions enter the mass spectrometer for filtering and detection. To use the NanoSpray source, you raust replace the standard QSTAR curtain plate with a new curtain plate designed to bring the emitter tip into closer proximity to the orifice plate hole for improved transmission of ions. The NanoSpray source operates with a minimal curtain gas setting, and is not recommended for higher flow rates that require curtain gas to ensure betten declustering.
As a "soft" ionization technique, nanospray is particularly useful for analyzing biological samples such as proteins while using very small sample amounts. With the Continuous NanoSpray and MicrolonSpray heads, you can also Lake full advantage of capillary chromatography.
The Continuous NanoSpray head accommodates low sample flows from 10 to 500 nL/min of different solvent compositions, and is ideally suited for analysis of complex samples using capillary LC systems. The Continuous NanoSpray is also convertible to a Discrete NanoSprayTM with flow rates from 20 to 40 nL/min when analysis of a single sample over a period of time is required. The MicrolonSpray head accommodates samples from 10 to 1000 nL/min with very low sample consumption.
Features of the NanoSpray Source
The NanoSpray source has the following features:
- Near 100% sample utilization.
- Minimal sample requirement.
- High sensitivity, as the ionization technique results in fine droplets for ionization.
- Ease of installation and exchange for other ion sources with the QSTAR series of instruments.
- CCTV monitors for positioning the emitter accurately and for observing spray.
Continuous NanoSpray Head Features
Sorne of the features of the Continuous NanoSpray head include the following:
- Functions with flow rates from 10 to 500 nL/min.
- Interfaces to any liquid chromatography system.
Discrete NanoSpray Head Features
Some of the features of the Discrete NanoSpray head include the following:
- Functions with flow rates from 20 to 40 nL/min.
- Ahle to analyze a srnall sample over long periods of time.
- Low sample consumption.
MicrolonSpray Head Features
Some of the features of the MicrolonSpray head include the following:
-
Able to function with flow rates from 10 to 1000 nL/min depending on
the internal diameter (2 to 50 nm) of the fused silica tubing used. - Ahle to ionize 100% aqueous to 100% organic solvents.
- Positive and negative ion mode analyses.
- High sensitivity for biological compounds.
- Formation of molecular Ions with no thermal degradation.
- Allows ionization of compounds in the kilodalton mass range.
- Very low sample consumption.
- Interfaces to any liquid chromatography system.
NanoSpray Source Component
Overview
The main components of the NanoSpray source include the following:
- Source frame with cover and brackets.
- Three source heads.
- Two cameras for viewing the spray, with accompanying monitors.
- One illuminator.
- Rails on which the source moves forward and back.
- x-y-z positioning unit with knobs for adjustment of the emitter tip relative to the curtain plate.
The NanoSpray source frame includes brackets for the cameras and the illuininator attachment. The source frame also supports the rails and x-y-z positioning unit. For more information, see the following figure, NanoSpray source housingside view.
NanoSpray source housingfront view
For the Continuous NanoSpray head, the universal arm Nolds the source head into which you insert the union joining the fused silica or LC column and the emitter tip. Electrical connection for the spray voltalte is made from the instrument to the union holder on the spray arm and thus the union, placing a potential on the sample.
The Discrete NanoSpray is held in place by an adapter attached to the universal arm, while the MicrolonSpray head attaches directly to the universal arm. Electrical connection for the spray voltage is made from the instrument to the top of the source heads.
When the source head is pulled back from the instrument, the high voltage to the head is disconnected. To engage the high voltage, the positioning unit must slide completely into place against the source housing.
CAUTION: To avoid damaging the tip, when sliding the positioning unit toward the curtain plate with an emitter tip in place, ensure that you have first used the x-y-z knobs to slide the x-y-z positioning unit as far away from the Instrument as possible to avoid striking the tip an the curtain plate.
Flow Types and Emitter Tips
WARNING! Always wear safety glasses when working with emitter tips, and follow all safety precautions and procedures recommended in the manufacturer's documentation.
Selection of flow type and emitter tips is dependent upon your application.
Discrete NanoSpray results in betten quality data when scanning an a
particular ion or making extensive study of one protein in very small amounts. Continuous NanoSpray with LC pre-separation gives best results for complex samples, such as protein digests where you are interested in all peptides.
Emitter tips can be uncoated or either distaf- or proximal-coated with a conductive material that transmits the charge to the liquid passing through the tip, faciIitating ion evaporation.
Uncoated and Coated Fused Silica Emitter Tips
Emitter tips can be uncoated or coated with a conductive material to facilitate ionization of the sample passing through the Union and tip. If coated tips are used, distal-coated tips are suggested; the tips are coated on pari of the needle but not at the outlet end. (Proximal-coated tips are coated on the outlet end.)
The emitter tip is seated in a PEEK sleeve inside the conductive ferrule and Valco union supplied with the ion source. Electrical connection to the union is supplied to the source head from the mass spectrometer.
WARNING! The NanoSpray source needle is very sharp. Extra care should be used when handling the needle to avoid injury. Used needles shall be disposed of in an appropriate "sharps" or similar container that renders them inaccessible.
Cameras
Two cameras focused on the emitter tip and curtain plate hole allow you to view the NanoSpray operation. The cameras are inounted in brackets on the source housing, and can be adjusted for proximity, direction, and focus. Two monitors Show the camera outputs.
Illuminator
A single illuminator provides light for observing the orifice and tip.
Rails
The source head positioning unit can be pulled back along the rails to provide access to the heads. The unit raust be pushed completely into position against the source housing to properly engage the high voltage. Once the unit is in
place against the source housing, the location of the emitter tip can be adjusted using knobs on the x-y-z positioning unit.
CAUTION! To avoid damaging the tip, when sliding the positioning unit toward the curtain plate with an emitter tip in place, ensure that you have first used the x-y-z knobs to slide the
x-y-z positioning unit as far away from the Instrument as possible to avoid striking the tip on the curtain plate.
When the unit is pulled back along the rails from the source housing, the electrical high-voltage is disengaged, shutting off power to the source head.
X-Y-Z Positioning Unit with Adjustment Knobs
The source head moves in relation to the curtain plate hole through adjustments to the x-y-z positioning unit's adjustment knobs.
The adjustment knobs provide the following controls:
- Fine movement toward and away from the curtain plate.
- Coarse movement toward and away from the curtain plate.
- Vertical movement.
- Horizontal movement.
CAUTION! To avoid damaging the tip, when sliding the positioning unit toward the curtain plate with an emitter tip in place, ensure that you have first used the x-y-z knobs to slide the x-y-z positioning unit as far away from the instrument as possible to avoid striking the tip an the curtain plate.
