40 Agilent 1100 Series Valves

4 Valve Applications

Sample enrichment and Sample stripping

Figure 22 on page 39 illustrates how the Agilent 1100 Series 2 position/ 6 port

valve can be used for sample stripping. In valve position 1 Pump A transfers

the complete sample matrix onto the pre-column 1, where the matrix is

trapped while the analytes are eluted and flushed to column 2 for analysis.

Then the valve switches to position 2. Now pump B backflushes the matrix to

the waste, while pump A continues to deliver solvent to the analytical column,

where the analytes are separated and analyzed.

Agilent Technologies offers a capillary kit for sample enrichment and stripping

as displayed in Table 11 on page 40 and Table 12 on page 41.
