The SIL-20AC XR is a total volume injection type (direct injection) autosampler that, in addition to a high-speed injection function and high-precision function for injecting trace quantities, features an improved high-pressure valve that increases the pressure resistance (max. allowable pressure: 66 MPa). The internal volume of the high-pressure valve was reduced to suppress sample diffusion, which is especially suited to high separation analysis. The 20ACXR includes a sample cooler that allows samples in sample racks to be stored at a constant temperature between 4 °C and 40 °C.
