Prepare the Test Sample
You are now ready to prepare your sample. For preparation of samples for
automated injection, please refer to the CP-8400 AutoSampler section on page
121.
You may inject your sample neat or diluted in a solvent. The Varian PFPD test
sample should be diluted 1:30 in iso-octane if you intend to use it for a splitless
injection. The choice of solvents depends on a number of factors, including
component solubility, type of detector and polarity of the analytical column.
Select solvents that match the polarity of your column.
