主要规格及技术指标

1260 Infinity II Isocratic Pump, maximum pressure 600bar. Includes
isocratic pump, column, connecting capillaries, solvent cabinet,
solvent bottles and CAN cable.
Mobile Phase: The solvent should be of HPLC-grade purity and needs to be filtered before use.
Pump: It is a binary pump, the 1260 Pump with model G7111. The flow rate setting range is 0 - 10 ml/min, and the pressure limit is 0 - 200 bar.
Pressure Limit: The upper and lower pressure limits should be set reasonably. The upper pressure limit (Max) should not exceed the maximum pressure that the column and the instrument can withstand. Generally, it should be set about 20 bar higher than the normal analysis pressure. The lower pressure limit (Min) is usually set about 20 bar lower than the normal analysis pressure.
Autosampler: There are two sample trays, P1 and P2. The input format is, for example, P1-A1, which represents position A1 in the front sample tray of the first-layer drawer, and the rear sample tray of the first layer is P2. The model is G7129A 1260 Vialsampler, with an injection volume range of 0 - 100 microliters.
Column Oven: It is temperature-controllable within the range of 4 - 85℃. The model is G7116A 1260MCT.
Detector Parameters
There are two detectors. One is a UV detector with the model 1260VWD G7114A. The wavelength setting range is 190 - 600 nm.
The other is an RID (Refractive Index Detector) with the model 1260RID G7162A. This detector can only be used for isocratic elution. It is recommended to set the detector temperature at least 5°C higher than the room temperature.
流动相：
溶剂应达到 HPLC 级纯度，且在使用前需进行过滤。

泵：
该泵为二元泵，型号为 G7111 的 1260 泵。流量设定范围为 0 - 10 ml/min，压力限制为 0 - 200 bar。

压力限制：
应合理设置上下限压力。上限压力（Max）不应超过色谱柱和仪器所能承受的最大压力。通常，应将其设置为比正常分析压力高出约 20 bar。下限压力（Min）则通常设置为比正常分析压力低约 20 bar。

自动进样器：
配备两个样品托盘，分别为 P1 和 P2。输入格式示例为 P1-A1，表示第一层抽屉前部样品托盘的 A1 位置，第一层后部样品托盘则标记为 P2。自动进样器型号为 G7129A 1260 Vialsampler，进样体积范围为 0 - 100 微升。

柱温箱：
温度可在 4 - 85℃ 范围内进行控制。型号为 G7116A 1260MCT。

检测器参数：
系统配备两个检测器。

一个是紫外检测器，型号为 1260VWD G7114A。波长设定范围为 190 - 600 nm。
另一个是折射率检测器（RID），型号为 1260RID G7162A。该检测器仅适用于等度洗脱。建议将检测器温度设置为至少比室温高出 5°C。
