13.2.2 Loading the Vials
WARNING
Wear appropriate Personal Protection Equipment (PPE)
as advised by the MSDS of the compound(s) being used.
Loading of vials is accomplished in a manner which best preserves the integrity of
the sample. The HSS works on the basis of heating a sample to partition the
volatiles between the sample and the headspace within the vial. Just as heat drives
off volatiles, aeration also removes volatiles from a sample.
NOTE: Use Volatile Organic Compound (VOC) free water to rinse a syringe (either
25 or 50 mL size Luer-Lock tip syringe is suggested). No needle is required
for this syringe.
To load a water sample into the vial:
1 Rinse a small clean vessel (such as a beaker) with VOC-free water and discard
the water.
2 Pour some VOC-free water in the rinsed vessel for rinsing of the sample
syringe.
3 Rinse the sample syringe with VOC-free water by drawing the water up into the
syringe through the tip. Push the syringe plunger to discard the water. Repeat
three times.
4 Remove the plunger from the sample syringe. Hold the sample syringe at an
angle with the large open end up, and the small end (where a needle would be)
stopped against a gloved finger. See
Figure 13-4 . Carefully transfer the sample
into the sample syringe.
