Sample manager features

Topic LCI-USG-0073, 最近更新 11/28/2023

The sample manager uses a direct injection mechanism to inject samples drawn from vials and plates onto a chromatographic column..

The Alliance iS Sample Manager maintains sample temperature, aspirates precise samples, and then injects them into the mobile phase using a flow-through-needle (FTN) design. The needle becomes part of the fluidics path when the sample is injected onto the column. The mobile phase cleanses the needle during the run, ensuring complete sample recovery and minimizing carryover. Additionally, the sample positioning mechanism controls the location of the sample plates relative to the sample needle, reducing extra system volume.

The standard configuration supports sample injection volumes of 0.1 to 100 μL. Optional extension loops can extend the injection volume up to 2000 μL. The sample temperature is regulated within a range of 4 °C (39.2 °F) to 40 °C (104 °F).

Note: A 100-µL extension loop is included in the standard configuration.

The sample manager features:

Three-plate sample capacity
Precise sample metering
Accurate sample temperature control
Exceptional carryover performance (0.002% maximum)
Consistent solvent consumption
Puncture robustness
