Ion Max and Ion Max-S API Source Housings

This chapter describes the Ion Max and Ion Max-S atmospheric pressure ionization (API) source

housings (see Figure 1). The Ion Max and Ion Max-S API source housings provide the same

functionality with the following exceptions: the Ion Max has an adjustable probe mount and a

front door with a view window. The adjustable probe mount allows you to adjust the XY position

of the probe and the front door makes it easier to install additional options. If your system uses the

Ion Max-S API source housing, you can only adjust the probe depth.

Introduction

2Ion Max and Ion Max-S API Source Hardware Manual Thermo Scientific

Introduction

All mass spectrometers require an ionization source (ion source) to generate ions. The popularity of

LC/MS techniques in mass spectrometry has made atmospheric pressure ionization (API) sources

the industry standard. The specific process used to ionize the sample is referred to as the ionization

mode. The Ion Max™ and Ion Max-S™ API sources can be configured to operate in any of several

API modes, including electrospray ionization (ESI), heated-electrospray ionization (H-ESI),

atmospheric pressure chemical ionization (APCI), and atmospheric pressure photo-ionization

(APPI). The ion guides transmit the ions produced in the API source into the mass analyzer, where

they are separated according to their mass-to-charge ratios.

Tab le 1 lists which API source housing is provided with your mass spectrometer.

With both of the Ion Max API source housings, you can switch between ionization modes without

using specialized tools. Pressure in the ion source housing is kept at atmospheric levels, which

reduces the chemical noise that nebulized gases can cause when they are not properly evacuated

from the ion source. During operation, the external surface of the ion source housing can become

hot. The ventilation holes in the ion source housing aid cooling when the system is placed in

Standby mode. Allow the system to cool for a minimum of 20 minutes before touching the ion

source housing.

The probe mounting angle is fixed at the optimum angle for signal intensity and ion source

robustness. You can use the probe adjustment markers (A, B, C, and D depth markers) to record

the probe position used during ionization optimization. View ports on the ion source housing

allow you to view the probe while positioning it. These ports also help you add accessories.

Corrosion of the ion source caused by liquid leaks or poor drainage is prevented by these features:

• The drain size and angle allow eluants to flow directly from the probe into the drain when

auxiliary gases are off. For liquids that do not enter the drain directly, the floor of the ion

source interior is specially sloped to enable maximum drainage of collected eluants.

• The zero dead volume (ZDV) grounding unions that connect the solvent flow from the liquid

chromatograph or the syringe pump to the ESI or HESI-II probe sample inlets are offset to

prevent liquid leaks from dripping into the source housing.

Both of the API source housings incorporate a universal mounting platform and interface for use

with ESI, H-ESI, APCI, and APPI ionization sources. For information on the analysis of ions

produced by the API sources, refer to the hardware manual that comes with your mass

spectrometer.

hot enough to burn your skin.

Functional Description of the API Source Housing

Thermo Scientific Ion Max and Ion Max-S API Source Hardware Manual 3

Functional Description of the API Source Housing

The Ion Max and Ion Max-S API source housings include two nitrogen inlets, a drain port for

waste liquid, a vaporizer cable for the APCI or HESI-II probe heaters, and an 8 kV cable for the

electrospray needle (ESI) or corona discharge needle (APCI).

The Ion Max housing also includes a door to access the API probe and a movable probe port for

precise probe positioning. You use the micrometer in front of the probe port to move the probe

nozzle closer to or farther away from the ion source interface.

Figure 2 shows the vaporizer cable, 8 kV cable, and nitrogen lines on the top portion of the Ion

Max housing. In the H-ESI and APCI modes, the vaporizer cable provides power to the probe

heater. In the ESI mode, the vaporizer cable remains connected to the interlock socket. In the ESI

and H-ESI modes, the 8 kV cable supplies current to the ESI needle. In the APCI mode, the 8 kV

cable supplies current to the APCI corona needle attached to the source housing. For all three

ionization modes, the auxiliary and sheath gas lines supply nitrogen flow to the probes.

The API source housings have high voltage safety interlock switches that turn off the following

voltages:

• ESI needle voltage (or APCI corona discharge voltage)

• All API source and lens voltages, including the ion transfer capillary offset voltage

• The voltages on the ion guides

The following actions turn off these voltages:

• Removing the API source housing from the front of the mass spectrometer

• Removing the probe guide pin from the interlock block

• Disconnecting the vaporizer cable from the interlock socket on the API source housing (ESI

mode) or from the probe (H-ESI or APCI mode)

• Opening the Ion Max housing door

Adjusting the Probe Position on the Ion Max API Source Housing

Thermo Scientific Ion Max and Ion Max-S API Source Hardware Manual 5

Adjusting the Probe Position on the Ion Max API Source Housing

If you have the Ion Max API source housing, to maximize sensitivity, you can adjust the

side-to-side and front-to-back probe position by a few millimeters. Typically, you adjust the probe

position while optimizing the tune parameters for your analytes. For information on using the tune

software for your mass spectrometer, refer to the getting started guide for your mass spectrometer.

YTo adjust the probe position

• Using the micrometer on the front of the Ion Max source housing, adjust the front-to-back

probe position (see Figure 3).

• Using the knurled nut on the left side and the +1 to -1 markers on the top front of the Ion

Max source housing, adjust the side-to-side probe position (see Figure 3).

• Using the A, B, C, and D markers on the probe as a guide, adjust the probe depth.

Figure 3. Top view of the Ion Max source housing with a HESI-II probe

Note The position of the probe port on the Ion Max-S API source housing is not adjustable.

CAUTION Avoid burns. When the system is in operation, the surface of the source

housing can be hot enough to burn your skin. You can touch the micrometer and the

knurled nut while the system is in operation, but avoid touching other parts of the source

housing.

Removing the API Source Housing

You must remove the API source housing to access the APCI corona needle or the ion source

interface.

YTo remove the API source housing

1. Place the mass spectrometer in Standby mode.

2. If the mass spectrometer was recently in operation, allow time for the ion source housing to

cool to room temperature before you touch its external metal surface.

3. If a probe is connected to the source housing, disconnect the external liquid lines before

removing the source housing from the mass spectrometer.

4. Remove the drain tube from the ion source housing drain (see Figure 4).

Figure 4. View of the ion source housing locking levers and drain

5. Rotate the ion source housing locking levers 90 degrees to release the ion source housing from

the ion source mount assembly (see Figure 4).

6. Remove the ion source housing by pulling it straight off of the ion source mount assembly.

Place the housing in a safe location for temporary storage.

Note When the mass spectrometer is in Standby, the high voltage and nitrogen gas are off.

CAUTION Avoid burns. During operation, the external surface of the ion source housing

can become hot. Allow the ion source housing to cool to room temperature before

touching it from the mass spectrometer.

Figure 6 shows the ion sweep cone that has an offset orifice. The ion sweep cone on your ion

source mount assembly might look different from the one shown in Figure 6. Figure 7 shows

the two types of ion sweep cones available on Thermo Scientific mass spectrometers.

3. Reinstall the source drain assembly as follows:

a. Connect the source drain assembly to the ion source housing drain fitting (see “API Source

Housing Drain” on page 9).

b. Attach the free end of the hose to a waste container. Ideally, vent the waste container to a

fume exhaust system.

CAUTION Prevent solvent waste from backing up into the ion source and mass

spectrometer. Always ensure that liquid in the drain tube is able to drain to a waste

container and that the outlet of the drain tube is above the level of liquid in the waste

container.
