快速和通用的分析HPLC自动进样器

当配备有微量滴定板（高或低格式）或从高达108个标准1.5毫升样品瓶的自动进样器AS 6.1L最多可以从768个位置注入。该样品的交叉污染被最小化显著由于一个高度有效的内部和外部针头清洗过程。此自动进样器也是快速和灵活的：一个完整​​的样品注射周期需要小于一分钟，包括针头清洗。三种不同的喷射模式被支持;“full loop filling” (highest precision and reproducibility), “partial loop filling” (variable volumes, e.g. for dilution series) and “µl pickup” (loss-free injection of extremely small sample volumes), allowing the user to optimize sample usage. The headspace pressure function prevents bubbles from forming in the vial during sample uptake. Precolumn derivatization is supported. For high-pressure injections, the autosampler is equipped with a so-called ILD™ valve (Intermediate Loop Decompression). This valve consists of a rotor-stator combination and includes a central port for depressurizing. For high-pressure applications, the sample loop is depressurized prior to receiving the sample. This way, the sample is not diluted with a solvent. Because the valve is switched extremely fast, pressure spikes are reduced. Analyses are more precise and wear of the column is reduced.
