Setting Up Sample Introduction Techniques
You can introduce samples into the MS using the external syringe pump, divert/inject valve,
and LC pumps to infuse or inject samples.
• Setting Up H-ESI or Low Flow H-ESI Direct Infusion
• Setting Up High-Flow Infusion Without an Autosampler
• Setting Up Loop Injections for Flow-Injection Analysis
• Setting Up Injections Using the Autosampler
Setting Up H-ESI or Low Flow H-ESI Direct Infusion
The sample is infused from the syringe pump into the API source. You use this technique to
calibrate the MS and infuse samples. Before you do this procedure, complete Appendix B,
“Setting Up the Syringe with the Syringe Pump.” and place your sample in the syringe.
This section describes how to set up:
• H-ESI direct infusion
• Low-flow H-ESI direct infusion
Setting Up H-ESI Direct Infusion
If you are going to do a calibration, follow these precautions.
CAUTION Do not wear nitrile gloves when you are working with EMRS. Nitrile gloves are
made with diphenylguanidine, which is soluble in EMRS. If diphenylguanidine
contaminates the EMRS, a peak at m/z 212 will be in the spectrum.
