3.1.4 Filling the Vials and Installing the Caps
NOTE To prevent contamination when doing trace-level
analyses, use forceps to handle the vials and caps.
Also, avoid touching any surface that will be wetted
with sample.
1. After rinsing, place the empty vials into a vial tray (for 0.5 mL vials,
P/N 068948; for 5.0 mL vials, P/N 068947).
2. Fill the vials with either sample or rinse solution until the liquid in the
vials reaches the top of the tray (see Figure 3-1 ). (Using a pipette
simplifies filling the 0.5 mL vials.) After filling, inspect the vials to
make sure no air bubbles are trapped at the bottom.
NOTE Do not underfill the vials. This may result in
insufficient sample being loaded for the first
injection.
A cap must be installed in each vial in order for the autosampler to
operate correctly. A vial without a cap will be sensed as an empty
position.
