The Reference Inlet System
This section introduces the reference inlet system. Information on how to set
up the system is provided in the chapter
Reference Inlet System
.
Introduction
The recommended way to introduce a sample for tuning and mass
calibration in electrospray is to use the reference inlet system.
Functional Description
As shown in Figure 1-20, the reference inlet system consists of a pressurized
reservoir containing the reference sample and a PEEK delivery tube. One
end of the PEEK delivery tube is inserted into the reference inlet reservoir,
while the other end is attached to the switching valve. When the pressure in
the reservoir is increased, the sample is forced through the PEEK tube and
infused directly into the 100 µL sample loop.
