Abstract
A sampler for liquid chromatography is described. The sampler includes an injection valve and a sample loop. The injection valve includes one waste port, two sample loop ports, and two high-pressure ports. The sample loop port includes a first loop part and a second loop part. The injection valve can be configured to have LOAD position and INJECT position. The injection valve can also be configured to have one or more additional positions such as a FULL PURGE position, a PUMP PURGE position, and a NEGATIVE PRESSURE position.
