HPLC Autosampler - SIL-40/SIL-40C

The most economical pair of Shimadzu’s autosamplers provide unattended sample injection and use a needle-in-flowpath design to minimize carryover. They offer sample pretreatment, loop injection, and optional inner and outer needle rinsing capability. Model SIL-40C is equipped with an air cooling mechanism for temperature control down to 4oC to protect thermally-sensitive samples. Both autosamplers support shallow- and deep-well MTP, as well as a wide ranges of vial volumes. For additional sample capacity, up to three plate changers (temperature controlled with the SIL-40C) can be added. SIL-40A/40C autosamplers have a pressure tolerance of 44 MPa (440 bar) and are recommended with the LC-40D pump.

• Features a needle in the flow path design to minimize carryover.
• Standard sample loop (100 µL), an optional sample loop (500 or 2000 µL) and a fixed-loop configuration (5 or 20 µL) are available.
• Total injection method: 0.1 to 100 µL in increments of 0.1 µL from 0.1 to 9.9 µL, and 1 µL from 10-50 µL.
• Performs sample pretreatment including dilution, reagent addition, co-injection of samples, stacked injection, and overlapped injection.
• Temperature control from 4 to 45°C (± 2°C accuracy,) with a forced air cooling mechanism to reduce condensation (SIL-40C only).
• Industry-leading cycle time of ≤ 7 seconds.
• Injection volume repeatability: RSD ≤1.0% for 0.5-0.9 µL, RSD ≤0.5% for 1.0-1.9 µL, RSD ≤0.25% for 2.0-4.9 µL, RSD ≤0.15% for injections ≥5.0 µL.
• Injection volume accuracy of ±1% for 5 μL injections (n=20).
• Carryover performance: 0.0025% (no needle rinsing) and 0.0005% (with rinse).
• Equipped with a static rinse port to rinse the outside of the needle before and/or after aspirating sample. An active external needle rinse pump can be added as an option.
• A 3-solvent internal rinse option is available to clean the inside of the needle and loop after sample injection to further reduce carryover.
• A dual injection mechanism can be installed for high throughput operation or complementary analysis.
• Maximum pressure rating of 44 MPa (440 bar).
