Autosampler and analysis system and method including same

An automatic sampler includes a carrier for receiving a plurality of sample containers, each sample container having a tip and a visible indicia. The visible indicia are located below a top plane defined by the top end. The autosampler includes: an optical sensor configured to read a visible marker and generate a corresponding output signal, and having a line of sight; a controller configured to receive an output signal; and a sampling system that draws a sample from the sample container. The autosampler is operable to relatively move the optical sensor and/or carrier such that a line of sight intersects the visible indicia of a selected one of the sample containers, where the line of sight extends downwardly from a height higher than the top plane height; an oblique angle is formed between the top plane; and extends through a gap between a selected sample container and an adjacent sample container. 一种自动取样器，包括用于接收多个样本容器的载体，每个样本容器具有顶端和可见标记。可见标记位于由顶端限定的顶平面下方。该自动取样器包括：光学传感器，其被配置成读取可见标记并产生对应的输出信号，并且具有视线；控制器，被配置成接
