SIL-20A/20AC
SIL-20A - High-Throughput Analysis
A total-volume injection type autosampler, the SIL-20A enables high-speed injection and high-throughput sample processing without wasting sample. It is designed to ensure greater stability, with improved durability attained through modifications in valves and sample loops. Multiple vial and plate types are supported, and a control vial rack isolates standards from analytical samples.
SIL-20AC - Efficient Sample Cooling
The SIL-20AC is equipped with a sample cooler with a built-in dehumidifier to minimize condensation problems. Samples can be maintained at a fixed temperature from 4ºC to 40ºC. Temperature equilibration is rapid and uniform, so heat or cold sensitive sample constituents remain stable.

Features of SIL-20A/20AC
Near-Zero Carryover Adsorption of sample constituents has been reduced to an absolute minimum. Enhancements include:
- Special needle treatment (patent pending) - masks active sites and minimizes ionic interactions
- One piece injection port/needle seal at valve center - eliminates sample transfer tubing
- Redesigned needle seal to minimize surface area
- Low-adsorption valve materials
These advancements combine to eliminate cross contamination - even with difficult basic and hydrophobic compounds. For especially difficult samples, dual-solvent rinsing is available.
High Speed/Throughput - 10s for a 10 µL injection Ultra-high-speed sample processing - 10 seconds for a 10 µL injection - is now possible with the SIL-20A/20AC. Used together with a high-speed separation column makes an analysis cycle time of less than one minute a reality.
Precise Sample Injection Greater injection volume accuracy has been attained by incorporating a high-performance precision metering pump. Injection volumes of less than 1 µL are possible, and the direct injection method means valuable samples are never wasted.
Optional Rack Changer Significantly Increases Sample Capacity
With increased speed, capacity becomes a limiting factor for unattended operation. The optional rack changer automatically loads microplates into the SIL-20A/AC sample compartment. The 12-plate capacity ensures convenient processing of over 1000 samples. The "C" model changer has the same plate capacity and incorporates a 4ºC to 40ºC cooling function, matching that of the SIL-20AC.
