The SIL-20A is a total volume injection type (direct injection) autosampler that enables high-speed injection and multi-analyte processing. Materials used in needle, valve, and other flow lines were closely considered and a needle rinsing function is provided to carefully minimize cross-contamination (carryover), which is especially useful for high-precision LC-MSMS analysis.
Features/Applications: Outstanding reproducibility and accuracy for trace volume injection. A needle rinsing function is included standard to minimize cross-contamination (carryover). It also allows high speed injection. (direct injection, specialized needle coating, and PEEK rotor)
