The SIL- 20AC autosamplers used with the Prominence UFLC system permit ultra-fast analysis while maintaining the injection accuracy and durability
requirements demanded of an HPLC system. The retention time reproducibility and injection volume reproducibility are within 0.3 % after endurance testing over 100,000 cycles, results similar to those achieved with standard HPLC.
Injection method Total-volume sample injection, variable injection volume
Maximum operating pressure 20 MPa
Injection-volume setting range 0.1 to 100 μL (standard), 0.1 to 2,000 μL (option)
Number of processed samples 175 (1 mL vials), 70 (1.5 mL vials), 50 (4 mL vials) 192 (two 96-well MTP/DWP), 768 (two 384-well MTP/DWP) Also, ten 1.5 mL vials in addition to each of the above.
Injection-volume accuracy 1% max (specified conditions)
Injection-volume precision RSD: 0.3% max. (specified conditions, typically 0.2% RSD max)

Number of repeated injections 30 max. per sample
Needle rinsing Set freely before and after sample injection
Sample cooler Block cooling/heating, used together with defumidifying function, 4 to 40°C
