Preparing Solvent and Waste Bottles
The solvent bottles hold solvent for rinsing the syringe between injections. The
injector dispenses the solvent washes and sample washes into waste bottles.
The number of samples that can be analyzed may be limited by the wash or
waste bottle capacity shown in Figure 51 and Figure 52.
Selecting the bottles
Solvent and waste bottles can be closed with either diffusion caps (a plastic
cap with a hole; it retards evaporation while letting the needle enter freely) or
septa. Agilent Technologies recommends diffusion caps (See Figure 50) over
septa for two reasons:
• The diffusion cap allows multiple entrances into a bottle without
contaminating the liquid inside the bottle with small pieces of septum
material.
• For common solvents, the rate of diffusion out of the bottle is less with a
diffusion cap than with a septum that has been punctured with a standard
syringe needle.
