Before the test, the pump is flushed with solvent in order to remove air bubbles, as air bubbles are compressed during the test and therefore would appear as leaks. Using a degasser is highly recommended. 110 InfinityLab LC Series 1260 Infini ty II Binary Pump User Manual 7 Test Functions and Calibration Pump","chunk_index":272,"source_document_id":2}
