Injection Mode
Injection Principle
A unique sequence of valve switching and syringe dispenser
controlled sample withdrawal enables the ProStar 430 to inject
sample volumes in a range from a few microliters to milliliters in
a simple and reproducible manner.
Therefore three different modes of injection can be selected :
- Full loop: The sample loop is completely (quantitatively)
filled with sample resulting in the maximum
reproducibility.
- Partial loopfill: The sample loop is partially filled with
sample; low sample loss and programmable injection
volumes.
- µL pick-up: After removal from the vial the sample
volume is transported into the loop with solvent from
another vial resulting in no sample loss.
