Emitter Tip Troubleshooting Tips

Corrective Action

Possible Cause

Symptom

a. Supply zero air for Gas 1.

Note: 

Make sure to spin the samples

before placing them in the autosampler
vial, so that no particulate in the
sample vial can clog the system.

b. Use MS-grade solvent. Refer to 

Solvents

.

c. Flush thoroughly before and after using

[Glu1]-Fibrinopeptide B.

d. Examine the blunt end of the emitter tip

under a microscope. Recut the emitter
tip. Refer to 

Cleaving an Emitter Tip

.

e. Make sure that sample flow does not

stop for more than three minutes while
the tip is in the spraying position, and
the interface heater is on (50 °C to 100
°C). When the sample flow stops, move
the X-Y-Z positioning unit away from the
ion source interface, or set IHT to 0 °C.

f. Reduce IHT to 50 °C to 100 °C.

a. The incorrect gas is supplied for Gas 1.

b. Solvent quality is poor.

c. The emitter tip and infusion line were not

flushed before and after a
[Glu1]-Fibrinopeptide B infusion.

d. The emitter tip is poorly cut.

e. Sample flow has stopped for several

minutes while the interface heater is on,
resulting in melting or deforming of the
emitter tip.

f. IHT is too high.

Frequent clogging or
degrading of spray
with new tips
