快速和多功能分析高效液相色谱自动进样器

当配备有微量滴定板（高或低格式）或高达108标准1.5mL样品瓶时，自动进样器可以从多达768个位置注入。由于高效的内部和外部针刷手术，样品携带显着最小化。该自动进样器也快速灵活：一个完整​​的样品喷射循环需要不到一分钟，包括针状洗涤。支持三种不同的喷射模式;“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.
