There is a solution to sequences with a very long number of samples that require many washes. This is called solvent saver. Depending on the syringe volume configured, Mass Hunter enables selection of wash volumes at 50, 40, 30, 20 and 10 percent of the syringe volume. For a 10 micro liter syringe, we can choose a wash volume between 1 and 5 micro liters. When using solvent saver mode, a PTFE tipped syringe must be used, using this mode for a fitted syringe would drastically reduce it's lifetime. This is because washing in solvent saver mode is a little different then in maximum mode.
Insuring solvent vials are clean and not contaminated is essential in preserving longer syringe lifetime. If you observe particulates in the bottom of wash vials, you can try to use a cotton swab to remove it. Or if you see a wash vial like one on the right side, don't bother to clean it out, just replace it. Trying to save on small items such as wash vials is More....
