SECTION 5 - EXAMPLE APPLICATIONS
Before attempting any of the following example applications, take the time to ensure that your system is properly configured.
Ensure that all of the eluents have been made from high purity reagents and deionized water. All water used in the preparation
of eluents should be degassed, deionized water. For chemical purity requirements, see Section 4.3, Chemical Purity Requirements.
After running synthetic standards to calibrate your system, you may find that real sample matrices foul your columns. For this
reason it is always advisable to use a guard column to protect the analytical column. If column performance deteriorates and it
is determined that the guard or the analytical column has been fouled, refer to the column cleanup protocols in, Column Care.
If your sample matrices are relatively low in ionic concentration, you may be able to increase the sensitivity of your system by
using sample concentration techniques (see Section 3.2, Sample Concentrator).
